The company produces and markets non-proprietary medicinal products – injection preparations, tablets, capsules, eye drops. It was acquired by Valeant Pharmaceuticals International, Inc. (NYSE: VRX) (TSX: VRX) in 2011. Sanitas was established in 1922. As a public limited liability company Sanitas was registered in

292-560: A compound annual growth rate (CAGR) of 1.8% given the results of recent events (which includes the COVID-19 pandemic ). In historical terms, a pharmaceutical industry as an intellectual concept arose within the middle to late 1800s inside of certain nation-states with developed economies such as Germany , Switzerland , and the United States given that multiple businesses engaging in synthetic organic chemistry , such as

438-492: A 20% drop in those for which antibiotics were not effective. The report concluded that "it appears that the use of antibiotics, early diagnosis, and other factors have limited the epidemic spread and thus the number of these diseases which have occurred". The study further examined mortality rates for eight common diseases for which antibiotics offered effective therapy (syphilis, tuberculosis, dysentery, scarlet fever, whooping cough, meningococcal infections, and pneumonia), and found

584-517: A 56% decline over the same period. Notable among these was a 75% decline in deaths due to tuberculosis. During the years 1940–1955, the rate of decline in the U.S. death rate accelerated from 2% per year to 8% per year, then returned to the historical rate of 2% per year. The dramatic decline in the immediate post-war years has been attributed to the rapid development of new treatments and vaccines for infectious disease that occurred during these years. Vaccine development continued to accelerate, with

730-411: A Japanese biochemist working for the pharmaceutical company Sankyo, identified mevastatin (ML-236B), a molecule produced by the fungus Penicillium citrinum , as an inhibitor of HMG-CoA reductase, a critical enzyme used by the body to produce cholesterol. Animal trials showed very good inhibitory effect as in clinical trials , however a long-term study in dogs found toxic effects at higher doses and as

876-408: A biopsy of nervous tissue is taken from the brain or spinal cord to aid in diagnosis. Biopsy is usually requested after a mass is detected by medical imaging . With autopsies, the principal work of the neuropathologist is to help in the post-mortem diagnosis of various conditions that affect the central nervous system. Biopsies can also consist of the skin. Epidermal nerve fiber density testing (ENFD)

1022-446: A combination known as general pathology. Cytopathology (sometimes referred to as "cytology") is a branch of pathology that studies and diagnoses diseases on the cellular level. It is usually used to aid in the diagnosis of cancer, but also helps in the diagnosis of certain infectious diseases and other inflammatory conditions as well as thyroid lesions, diseases involving sterile body cavities (peritoneal, pleural, and cerebrospinal), and

1168-414: A compound is identified as a potential drug in order to establish its suitability as a medication. Objectives of drug development are to determine appropriate formulation and dosing , as well as to establish safety . Research in these areas generally includes a combination of in vitro studies, in vivo studies, and clinical trials . The cost of late stage development has meant it is usually done by

1314-438: A conclusive diagnosis, and a skin biopsy is taken to be examined under the microscope using usual histological tests. In some cases, additional specialized testing needs to be performed on biopsies, including immunofluorescence , immunohistochemistry , electron microscopy , flow cytometry , and molecular-pathologic analysis. One of the greatest challenges of dermatopathology is its scope. More than 1500 different disorders of

1460-472: A drug could be sold, and explicitly prohibited false therapeutic claims. The aftermath of World War II saw an explosion in the discovery of new classes of antibacterial drugs including the cephalosporins (developed by Eli Lilly based on the seminal work of Giuseppe Brotzu and Edward Abraham ), streptomycin (discovered during a Merck-funded research program in Selman Waksman's laboratory ),

1606-525: A fixative that stabilizes the tissues to prevent decay. The most common fixative is formalin , although frozen section fixing is also common. To see the tissue under a microscope, the sections are stained with one or more pigments. The aim of staining is to reveal cellular components; counterstains are used to provide contrast. Histochemistry refers to the science of using chemical reactions between laboratory chemicals and components within tissue. The histological slides are then interpreted diagnostically and

1752-549: A formal area of specialty was not fully developed until the late 19th and early 20th centuries, with the advent of detailed study of microbiology . In the 19th century, physicians had begun to understand that disease-causing pathogens, or "germs" (a catch-all for disease-causing, or pathogenic, microbes, such as bacteria , viruses , fungi , amoebae , molds , protists , and prions ) existed and were capable of reproduction and multiplication, replacing earlier beliefs in humors or even spiritual agents, that had dominated for much of

1898-471: A general examination or an autopsy ). Anatomical pathology is itself divided into subfields, the main divisions being surgical pathology , cytopathology , and forensic pathology . Anatomical pathology is one of two main divisions of the medical practice of pathology, the other being clinical pathology, the diagnosis of disease through the laboratory analysis of bodily fluids and tissues. Sometimes, pathologists practice both anatomical and clinical pathology,

2044-558: A heart attack were reduced by 42%. In 1995, Zocor and Mevacor both made Merck over US$ 1 billion. Endo was awarded the 2006 Japan Prize , and the Lasker-DeBakey Clinical Medical Research Award in 2008. For his "pioneering research into a new class of molecules" for "lowering cholesterol," Since several decades, biologics have been rising in importance in comparison with small molecules treatments. The biotech subsector, animal health and

2190-507: A highly toxic solvent that is now widely used as antifreeze. Under the laws extant at that time, prosecution of the manufacturer was possible only under the technicality that the product had been called an "elixir", which literally implied a solution in ethanol. In response to this episode, the U.S. Congress passed the Federal Food, Drug, and Cosmetic Act of 1938 , which for the first time required pre-market demonstration of safety before

2336-469: A number of companies developed products based on adrenal extracts containing varying purities of the active substance. In 1897, John Abel of Johns Hopkins University identified the active principle as epinephrine , which he isolated in an impure state as the sulfate salt. Industrial chemist Jōkichi Takamine later developed a method for obtaining epinephrine in a pure state, and licensed the technology to Parke-Davis . Parke-Davis marketed epinephrine under

2482-479: A number of firms generating dyestuffs derived from coal tar on a large scale, sought out new applications of their artificial materials in terms of human health . This trend to increased capital investment occurred in tandem with the scholarly study of pathology as a field advancing significantly, and a variety of businesses set up cooperative relationships with academic laboratories evaluating human injury and disease. Examples of industrial companies with

2628-437: A number of visual and microscopic tests and an especially large variety of tests of the biophysical properties of tissue samples involving automated analysers and cultures . Sometimes the general term "laboratory medicine specialist" is used to refer to those working in clinical pathology, including medical doctors, Ph.D.s and doctors of pharmacology. Immunopathology , the study of an organism's immune response to infection,

2774-543: A pathologist generally requires specialty -training after medical school , but individual nations vary some in the medical licensing required of pathologists. In the United States, pathologists are physicians ( D.O. or M.D. ) who have completed a four-year undergraduate program, four years of medical school training, and three to four years of postgraduate training in the form of a pathology residency . Training may be within two primary specialties, as recognized by

2920-493: A pharmaceutical focus that have endured to this day after such distant beginnings include Bayer (based out of Germany) and Pfizer (based out of the U.S.). The modern era of pharmaceutical industry began with local apothecaries that expanded for their traditional role of distributing botanical drug s such as morphine and quinine to wholesale manufacture in the mid-1800s, and from discoveries resulting from applied research. Intentional drug discovery from plants began with

3066-499: A protocol to discontinue their use. A series of experiments performed from the late 1800s to the early 1900s revealed that diabetes is caused by the absence of a substance normally produced by the pancreas. In 1869, Oskar Minkowski and Joseph von Mering found that diabetes could be induced in dogs by surgical removal of the pancreas. In 1921, Canadian professor Frederick Banting and his student Charles Best repeated this study and found that injections of pancreatic extract reversed

3212-467: A push for revisions of the FD&;C Act emerged from Congressional hearings led by Senator Estes Kefauver of Tennessee in 1959. The hearings covered a wide range of policy issues, including advertising abuses, questionable efficacy of drugs, and the need for greater regulation of the industry. While momentum for new legislation temporarily flagged under extended debate, a new tragedy emerged that underscored

3358-504: A reduction in initial public offerings being floated. A 2022 article articulated this notion succinctly by saying "In the business of drug development, deals can be just as important as scientific breakthroughs", typically referred to as pharmaceutical M&A (for mergers and acquisitions). It highlighted that some of the most impactful of the remedies of the early 21st Century were only made possible through M&A activities, specifically noting Keytruda and Humira . Drug discovery

3504-400: A result mevastatin was believed to be too toxic for human use. Mevastatin was never marketed, because of its adverse effects of tumors, muscle deterioration, and sometimes death in laboratory dogs. P. Roy Vagelos , chief scientist and later CEO of Merck & Co , was interested, and made several trips to Japan starting in 1975. By 1978, Merck had isolated lovastatin (mevinolin, MK803) from

3650-431: A series of such compounds, and was found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis , a disease untl then had been incurable and led inexorably to severe skin ulceration, neurological damage, and death. Ehrlich's approach of systematically varying the chemical structure of synthetic compounds and measuring the effects of these changes on biological activity

3796-416: A significant portion of all general pathology practice is concerned with cancer , the practice of oncology makes extensive use of both anatomical and clinical pathology in diagnosis and treatment. In particular, biopsy, resection , and blood tests are all examples of pathology work that is essential for the diagnoses of many kinds of cancer and for the staging of cancerous masses . In a similar fashion,

3942-568: A sleep aid beginning in 1904. Systematic investigations of the effect of structural changes on potency and duration of action led to the discovery of phenobarbital at Bayer in 1911 and the discovery of its potent anti-epileptic activity in 1912. Phenobarbital was among the most widely used drugs for the treatment of epilepsy through the 1970s, and as of 2014, remains on the World Health Organizations list of essential medications. The 1950s and 1960s saw increased awareness of

4088-492: A small fraction are eventually approved in most nations by government-appointed medical institutions or boards, who have to approve new drugs before they can be marketed in those countries. In 2010 18 NMEs (New Molecular Entities) were approved and three biologics by the FDA, or 21 in total, which is down from 26 in 2009 and 24 in 2008. On the other hand, there were only 18 approvals in total in 2007 and 22 back in 2006. Since 2001,

4234-425: A suspicious lesion , whereas excisional biopsies remove the entire lesion, and are similar to therapeutic surgical resections. Excisional biopsies of skin lesions and gastrointestinal polyps are very common. The pathologist's interpretation of a biopsy is critical to establishing the diagnosis of a benign or malignant tumor, and can differentiate between different types and grades of cancer, as well as determining

4380-561: A third of the global pharmaceutical market, with $ 340 billion in annual sales followed by the EU and Japan. Emerging markets such as China, Russia, South Korea and Mexico outpaced that market, growing a huge 81 percent. The top ten best-selling drugs of 2013 totaled $ 75.6 billion in sales, with the anti-inflammatory drug Humira being the best-selling drug worldwide at $ 10.7 billion in sales. The second and third best selling were Enbrel and Remicade, respectively. The top three best-selling drugs in

4526-459: A vast array of species, but with a significantly smaller number of practitioners, so understanding of disease in non-human animals, especially as regards veterinary practice , varies considerably by species. Nevertheless, significant amounts of pathology research are conducted on animals, for two primary reasons: 1) The origins of diseases are typically zoonotic in nature, and many infectious pathogens have animal vectors and, as such, understanding

4672-459: A wide range of other body sites. Cytopathology is generally used on samples of free cells or tissue fragments (in contrast to histopathology, which studies whole tissues) and cytopathologic tests are sometimes called smear tests because the samples may be smeared across a glass microscope slide for subsequent staining and microscopic examination. However, cytology samples may be prepared in other ways, including cytocentrifugation . Dermatopathology

4818-418: A wide variety of diseases, including those caused by fungi , oomycetes , bacteria , viruses , viroids , virus-like organisms, phytoplasmas , protozoa , nematodes and parasitic plants . Damage caused by insects , mites , vertebrate , and other small herbivores is not considered a part of the domain of plant pathology. The field is connected to plant disease epidemiology and especially concerned with

4964-496: Is a more recently developed neuropathology test in which a punch skin biopsy is taken to identify small fiber neuropathies by analyzing the nerve fibers of the skin. This test is becoming available in select labs as well as many universities; it replaces the traditional nerve biopsy test as less invasive . Pulmonary pathology is a subspecialty of anatomic (and especially surgical) pathology that deals with diagnosis and characterization of neoplastic and non-neoplastic diseases of

5110-478: Is a significant field in modern medical diagnosis and medical research . The Latin term pathology derives from the Ancient Greek roots pathos ( πάθος ), meaning "experience" or "suffering", and -logia ( -λογία ), meaning "study of". The term is of early 16th-century origin, and became increasingly popularized after the 1530s. The study of pathology, including the detailed examination of

5256-445: Is a small piece of tissue removed primarily for surgical pathology analysis, most often in order to render a definitive diagnosis. Types of biopsies include core biopsies, which are obtained through the use of large-bore needles, sometimes under the guidance of radiological techniques such as ultrasound , CT scan , or magnetic resonance imaging . Incisional biopsies are obtained through diagnostic surgical procedures that remove part of

5402-428: Is a subspecialty of anatomic pathology that focuses on the skin and the rest of the integumentary system as an organ. It is unique, in that there are two paths a physician can take to obtain the specialization. All general pathologists and general dermatologists train in the pathology of the skin, so the term dermatopathologist denotes either of these who has reached a certain level of accreditation and experience; in

5548-454: Is a very large study of efficacy in the intended patient population. Following the successful completion of phase III testing, a New Drug Application is submitted to the FDA. The FDA reviews the data and if the product is seen as having a positive benefit-risk assessment, approval to market the product in the US is granted. A fourth phase of post-approval surveillance is also often required due to

5694-404: Is also heavily, and increasingly, informed upon by neuroscience and other of the biological cognitive sciences . Mental or social disorders or behaviours seen as generally unhealthy or excessive in a given individual, to the point where they cause harm or severe disruption to the person's lifestyle, are often called "pathological" (e.g., pathological gambling or pathological liar ). Although

5840-534: Is also possible to take a Royal College of Pathologists diploma in forensic pathology, dermatopathology, or cytopathology, recognising additional specialist training and expertise and to get specialist accreditation in forensic pathology, pediatric pathology , and neuropathology. All postgraduate medical training and education in the UK is overseen by the General Medical Council. In France, pathology

6132-411: Is considered a subfield of anatomical pathology. A physician who specializes in neuropathology, usually by completing a fellowship after a residency in anatomical or general pathology, is called a neuropathologist. In day-to-day clinical practice, a neuropathologist generates diagnoses for patients. If a disease of the nervous system is suspected, and the diagnosis cannot be made by less invasive methods,

6278-439: Is divided into a number of subdisciplines within the distinct but deeply interconnected aims of biological research and medical practice . Biomedical research into disease incorporates the work of a vast variety of life science specialists, whereas, in most parts of the world, to be licensed to practice pathology as a medical specialty, one has to complete medical school and secure a license to practice medicine. Structurally,

Other notable new vaccines of the period include those for measles (1962, John Franklin Enders of Children's Medical Center Boston, later refined by Maurice Hilleman at Merck), Rubella (1969, Hilleman, Merck) and mumps (1967, Hilleman, Merck) The United States incidences of rubella, congenital rubella syndrome, measles, and mumps all fell by >95% in

6570-456: Is often applied in a context that is as much scientific as directly medical and encompasses the development of molecular and genetic approaches to the diagnosis and classification of human diseases, the design and validation of predictive biomarkers for treatment response and disease progression, and the susceptibility of individuals of different genetic constitution to particular disorders. The crossover between molecular pathology and epidemiology

6716-715: Is represented by a related field " molecular pathological epidemiology ". Molecular pathology is commonly used in diagnosis of cancer and infectious diseases. Molecular Pathology is primarily used to detect cancers such as melanoma, brainstem glioma, brain tumors as well as many other types of cancer and infectious diseases. Techniques are numerous but include quantitative polymerase chain reaction (qPCR), multiplex PCR , DNA microarray , in situ hybridization , DNA sequencing , antibody-based immunofluorescence tissue assays, molecular profiling of pathogens, and analysis of bacterial genes for antimicrobial resistance . Techniques used are based on analyzing samples of DNA and RNA. Pathology

6862-411: Is separated into two distinct specialties, anatomical pathology, and clinical pathology. Residencies for both lasts four years. Residency in anatomical pathology is open to physicians only, while clinical pathology is open to both physicians and pharmacists . At the end of the second year of clinical pathology residency, residents can choose between general clinical pathology and a specialization in one of

7008-427: Is sometimes considered to fall within the domain of clinical pathology. Hematopathology is the study of diseases of blood cells (including constituents such as white blood cells , red blood cells , and platelets ) and the tissues, and organs comprising the hematopoietic system. The term hematopoietic system refers to tissues and organs that produce and/or primarily host hematopoietic cells and includes bone marrow ,

7154-530: Is the best and most definitive evidence of disease (or lack thereof) in cases where tissue is surgically removed from a patient. These determinations are usually accomplished by a combination of gross (i.e., macroscopic) and histologic (i.e., microscopic) examination of the tissue, and may involve evaluations of molecular properties of the tissue by immunohistochemistry or other laboratory tests. There are two major types of specimens submitted for surgical pathology analysis: biopsies and surgical resections. A biopsy

7300-430: Is the core guide for pharmacists and clinicians. In many non-US western countries, a 'fourth hurdle' of cost effectiveness analysis has developed before new technologies can be provided. This focuses on the 'efficacy price tag' (in terms of, for example, the cost per QALY ) of the technologies in question. In England and Wales NICE decides whether and in what circumstances drugs and technologies will be made available by

7446-423: Is the generating of visual representations of the interior of a body for clinical analysis and medical intervention. Medical imaging reveals details of internal physiology that help medical professionals plan appropriate treatments for tissue infection and trauma. Medical imaging is also central in supplying the biometric data necessary to establish baseline features of anatomy and physiology so as to increase

7592-498: Is the most important risk factor for cardiovascular morbidity and mortality , in industrialized countries . Prior to 1940 approximately 23% of all deaths among persons over age 50 were attributed to hypertension. Severe cases of hypertension were treated by surgery. Early developments in the field of treating hypertension included quaternary ammonium ion sympathetic nervous system blocking agents, but these compounds were never widely used due to their severe side effects, because

7738-595: Is the process by which potential drugs are discovered or designed. In the past, most drugs have been discovered either by isolating the active ingredient from traditional remedies or by serendipitous discovery. Modern biotechnology often focuses on understanding the metabolic pathways related to a disease state or pathogen , and manipulating these pathways using molecular biology or biochemistry . A great deal of early-stage drug discovery has traditionally been carried out by universities and research institutions. Drug development refers to activities undertaken after

7884-415: Is the value of the publicly traded companies. Small Molecules modality had 58.2% of the valuation share down from 84.6% in 2003. Biologics was up at 30.5% from 14.5%. The valuation share of Chinese Pharma grew from 2003 to 2021 from 1% to 12% overtaking Switzerland who is now ranked number 3 with 7.7%. The United States had still by far the most valued pharmaceutical industry with 40% of global valuation. 2023

Although diagnosis and classification of mental norms and disorders is largely the purview of psychiatry—the results of which are guidelines such as the Diagnostic and Statistical Manual of Mental Disorders , which attempt to classify mental disease mostly on behavioural evidence, though not without controversy —the field

8176-615: Is widely used for gene therapy and disease diagnosis. Oral and Maxillofacial Pathology is one of nine dental specialties recognized by the American Dental Association , and is sometimes considered a specialty of both dentistry and pathology. Oral Pathologists must complete three years of post doctoral training in an accredited program and subsequently obtain diplomate status from the American Board of Oral and Maxillofacial Pathology. The specialty focuses on

8322-519: The Nobel Prize in Medicine for this discovery. Nonetheless, the dramatic decrease in deaths from infectious diseases that occurred prior to World War II was primarily the result of improved public health measures such as clean water and less crowded housing, and the impact of anti-infective drugs and vaccines was significant mainly after World War II. In 1928, Alexander Fleming discovered

Based on fundamental research performed by Gregory Pincus and synthetic methods for progesterone developed by Carl Djerassi at Syntex and by Frank Colton at G.D. Searle & Co. , the first oral contraceptive, Enovid , was developed by G.D. Searle & Co. and approved by the FDA in 1960. The original formulation incorporated vastly excessive doses of hormones, and caused severe side effects. Nonetheless, by 1962, 1.2 million American women were on

8614-409: The kidneys . In a medical setting, renal pathologists work closely with nephrologists and transplant surgeons , who typically obtain diagnostic specimens via percutaneous renal biopsy. The renal pathologist must synthesize findings from traditional microscope histology, electron microscopy , and immunofluorescence to obtain a definitive diagnosis. Medical renal diseases may affect the glomerulus ,

8760-416: The lungs and thoracic pleura . Diagnostic specimens are often obtained via bronchoscopic transbronchial biopsy, CT -guided percutaneous biopsy, or video-assisted thoracic surgery .

11388-429: The accuracy with which early or fine-detail abnormalities are detected. These diagnostic techniques are often performed in combination with general pathology procedures and are themselves often essential to developing new understanding of the pathogenesis of a given disease and tracking the progress of disease in specific medical cases. Examples of important subdivisions in medical imaging include radiology (which uses

11534-429: The activity of specific molecular pathways in the tumor. Surgical resection specimens are obtained by the therapeutic surgical removal of an entire diseased area or organ (and occasionally multiple organs). These procedures are often intended as definitive surgical treatment of a disease in which the diagnosis is already known or strongly suspected, but pathological analysis of these specimens remains important in confirming

11680-495: The addictive properties and abuse potential of barbiturates and amphetamines and led to increasing restrictions on their use and growing government oversight of prescribers. Today, amphetamine is largely restricted to use in the treatment of attention deficit disorder and phenobarbital in the treatment of epilepsy . In 1958, Leo Sternbach discovered the first benzodiazepine , chlordiazepoxide (Librium). Dozens of other benzodiazepines have been developed and are in use, some of

11826-401: The antibacterial effects of penicillin , but its exploitation for the treatment of human disease awaited the development of methods for its large scale production and purification. These were developed by a U.S. and British government-led consortium of pharmaceutical companies during the world war. There was early progress toward the development of vaccines throughout this period, primarily in

11972-476: The biological effects of these structural changes. By the 1890s, the profound effect of adrenal extracts on many different tissue types had been discovered, setting off a search both for the mechanism of chemical signalling and efforts to exploit these observations for the development of new drugs. The blood pressure raising and vasoconstrictive effects of adrenal extracts were of particular interest to surgeons as hemostatic agents and as treatment for shock, and

12118-621: The body, including dissection and inquiry into specific maladies, dates back to antiquity. Rudimentary understanding of many conditions was present in most early societies and is attested to in the records of the earliest historical societies , including those of the Middle East , India , and China . By the Hellenic period of ancient Greece , a concerted causal study of disease was underway (see Medicine in ancient Greece ), with many notable early physicians (such as Hippocrates , for whom

12264-404: The cost of developing a successful new drug ( new chemical entity , or NCE), has been estimated at US$ 1.3 billion (not including marketing expenses ). Professors Light and Lexchin reported in 2012, however, that the rate of approval for new drugs has been a relatively stable average rate of 15 to 25 for decades. Industry-wide research and investment reached a record $ 65.3 billion in 2009. While

12410-590: The cost of research in the U.S. was about $ 34.2 billion between 1995 and 2010, revenues rose faster (revenues rose by $ 200.4 billion in that time). A study by the consulting firm Bain & Company reported that the cost for discovering, developing and launching (which factored in marketing and other business expenses) a new drug (along with the prospective drugs that fail) rose over a five-year period to nearly $ 1.7 billion in 2003. According to Forbes, by 2010 development costs were between $ 4 billion to $ 11 billion per drug. Some of these estimates also take into account

12556-455: The data supporting the safety of thalidomide was incomplete. The firm continued to pressure Kelsey and the FDA to approve the application until November 1961, when the drug was pulled off the German market because of its association with grave congenital abnormalities. Several thousand newborns in Europe and elsewhere suffered the teratogenic effects of thalidomide. Without approval from the FDA,

12702-409: The development of tricyclic antidepressants in the 1960s. In 1903, Hermann Emil Fischer and Joseph von Mering disclosed their discovery that diethylbarbituric acid, formed from the reaction of diethylmalonic acid, phosphorus oxychloride and urea, induces sleep in dogs. The discovery was patented and licensed to Bayer pharmaceuticals , which marketed the compound under the trade name Veronal as

12848-525: The diagnosis, clinical management and investigation of diseases that affect the oral cavity and surrounding maxillofacial structures including but not limited to odontogenic , infectious, epithelial , salivary gland , bone and soft tissue pathologies. It also significantly intersects with the field of dental pathology . Although concerned with a broad variety of diseases of the oral cavity, they have roles distinct from otorhinolaryngologists ("ear, nose, and throat" specialists), and speech pathologists ,

12994-442: The disciplines, but they can not practice anatomical pathology, nor can anatomical pathology residents practice clinical pathology. Though separate fields in terms of medical practice, a number of areas of inquiry in medicine and medical science either overlap greatly with general pathology, work in tandem with it, or contribute significantly to the understanding of the pathology of a given disease or its course in an individual. As

13140-420: The examination of a biopsy or surgical specimen by a pathologist, after the specimen has been processed and histological sections have been placed onto glass slides. This contrasts with the methods of cytopathology, which uses free cells or tissue fragments. Histopathological examination of tissues starts with surgery , biopsy , or autopsy. The tissue is removed from the body of an organism and then placed in

13286-448: The extent that such laws did exist, enforcement was lax. In the United States, increased regulation of vaccines and other biological drugs was spurred by tetanus outbreaks and deaths caused by the distribution of contaminated smallpox vaccine and diphtheria antitoxin. The Biologics Control Act of 1902 required that federal government grant premarket approval for every biological drug and for the process and facility producing such drugs. This

13432-425: The fact that even the largest clinical trials cannot effectively predict the prevalence of rare side-effects. Postmarketing surveillance ensures that after marketing the safety of a drug is monitored closely. In certain instances, its indication may need to be limited to particular patient groups, and in others the substance is withdrawn from the market completely. The FDA provides information about approved drugs at

13578-686: The firm distributed Kevadon to over 1,000 physicians there under the guise of investigational use. Over 20,000 Americans received thalidomide in this "study," including 624 pregnant patients, and about 17 known newborns suffered the effects of the drug. The thalidomide tragedy resurrected Kefauver's bill to enhance drug regulation that had stalled in Congress, and the Kefauver-Harris Amendment became law on 10 October 1962. Manufacturers henceforth had to prove to FDA that their drugs were effective as well as safe before they could go on

13724-418: The first vaccine against Japanese Encephalitis . Hilleman later moved to Merck , where he played a key role in the development of vaccines against measles , mumps , chickenpox , rubella , hepatitis A , hepatitis B , and meningitis . Prior to the 20th century, drugs were generally produced by small scale manufacturers with little regulatory control over manufacturing or claims of safety and efficacy. To

13870-407: The form of academic and government-funded basic research directed toward the identification of the pathogens responsible for common communicable diseases. In 1885, Louis Pasteur and Pierre Paul Émile Roux created the first rabies vaccine . The first diphtheria vaccines were produced in 1914 from a mixture of diphtheria toxin and antitoxin (produced from the serum of an inoculated animal), but

14016-535: The fungus Aspergillus terreus , first marketed in 1987 as Mevacor. In April 1994, the results of a Merck-sponsored study, the Scandinavian Simvastatin Survival Study , were announced. Researchers tested simvastatin , later sold by Merck as Zocor, on 4,444 patients with high cholesterol and heart disease. After five years, the study concluded the patients saw a 35% reduction in their cholesterol, and their chances of dying of

14162-504: The hematopoietic system. In addition, the hematopathologist may be in charge of flow cytometric and/or molecular hematopathology studies. Molecular pathology is focused upon the study and diagnosis of disease through the examination of molecules within organs, tissues or bodily fluids . Molecular pathology is multidisciplinary by nature and shares some aspects of practice with both anatomic pathology and clinical pathology, molecular biology , biochemistry , proteomics and genetics . It

14308-485: The horizon. Pathology As a field of general inquiry and research, pathology addresses components of disease: cause, mechanisms of development ( pathogenesis ), structural alterations of cells (morphologic changes), and the consequences of changes (clinical manifestations). In common medical practice, general pathology is mostly concerned with analyzing known clinical abnormalities that are markers or precursors for both infectious and non-infectious disease, and

14454-425: The human host. To determine causes of diseases, medical experts used the most common and widely accepted assumptions or symptoms of their times, a general principle of approach that persists in modern medicine. Modern medicine was particularly advanced by further developments of the microscope to analyze tissues, to which Rudolf Virchow gave a significant contribution, leading to a slew of research developments. By

14600-431: The identity of a corpse. The requirements for becoming a licensed practitioner of forensic pathology varies from country to country (and even within a given nation ) but typically a minimal requirement is a medical doctorate with a specialty in general or anatomical pathology with subsequent study in forensic medicine. The methods forensic scientists use to determine death include examination of tissue specimens to identify

14746-490: The imaging technologies of X-ray radiography ) magnetic resonance imaging , medical ultrasonography (or ultrasound), endoscopy , elastography , tactile imaging , thermography , medical photography , nuclear medicine and functional imaging techniques such as positron emission tomography . Though they do not strictly relay images, readings from diagnostics tests involving electroencephalography , magnetoencephalography , and electrocardiography often give hints as to

14892-401: The immediate aftermath of widespread vaccination. The first 20 years of licensed measles vaccination in the U.S. prevented an estimated 52 million cases of the disease, 17,400 cases of mental retardation , and 5,200 deaths. Hypertension is a risk factor for atherosclerosis, heart failure , coronary artery disease , stroke , renal disease , and peripheral arterial disease , and

15038-911: The industry ecosystem with biotechnology companies playing an increasingly important role, and overall strategies being redefined accordingly. Some approved drugs, such as those based on re-formulation of an existing active ingredient (also referred to as Line-extensions) are much less expensive to develop. In the United States, new pharmaceutical products must be approved by the Food and Drug Administration (FDA) as being both safe and effective. This process generally involves submission of an Investigational New Drug filing with sufficient pre-clinical data to support proceeding with human trials. Following IND approval, three phases of progressively larger human clinical trials may be conducted. Phase I generally studies toxicity using healthy volunteers. Phase II can include pharmacokinetics and dosing in patients, and Phase III

15184-565: The involvement of intellectual property , in " brand " materials is specifically tied to a given company's history, or in both within different contexts. The industry's has various subdivisions (which include distinct areas such as manufacturing biologics ) are all subject to a variety of laws and regulations that govern entire financial processes including the patenting , efficacy testing, safety evaluation , and marketing of these drugs. The global pharmaceuticals market produced treatments worth $ 1,228.45 billion in 2020, in total, and this showed

15330-509: The isolation between 1803 and 1805 of morphine – an analgesic and sleep-inducing agent – from opium by the German apothecary assistant Friedrich Sertürner , who named this compound after the Greek god of dreams, Morpheus . Multinational corporations including Merck , Hoffman-La Roche , Burroughs-Wellcome (now part of Glaxo Smith Kline ), Abbott Laboratories , Eli Lilly and Upjohn (now part of Pfizer ) began as local apothecary shops in

15476-436: The isolation of tuberculosis-infected people were an ubiquitous feature of cities in developed countries, with 50% dying within 5 years of admission. A Federal Trade Commission report issued in 1958 attempted to quantify the effect of antibiotic development on American public health. The report found that over the period 1946–1955, there was a 42% drop in the incidence of diseases for which antibiotics were effective and only

15622-462: The larger pharmaceutical companies. The pharmaceuticals and biotechnology industry spends more than 15% of its net sales for Research & Development which is in comparison with other industries by far the highest share. Often, large multinational corporations exhibit vertical integration , participating in a broad range of drug discovery and development, manufacturing and quality control, marketing, sales, and distribution. Smaller organizations, on

15768-435: The largest body of research in veterinary pathology. Animal testing remains a controversial practice, even in cases where it is used to research treatment for human disease. As in human medical pathology, the practice of veterinary pathology is customarily divided into the two main fields of anatomical and clinical pathology. Although the pathogens and their mechanics differ greatly from those of animals, plants are subject to

15914-431: The late 1920s to early 1930s pathology was deemed a medical specialty. Combined with developments in the understanding of general physiology , by the beginning of the 20th century, the study of pathology had begun to split into a number of distinct fields, resulting in the development of a large number of modern specialties within pathology and related disciplines of diagnostic medicine . The modern practice of pathology

16060-435: The latter of which helps diagnose many neurological or neuromuscular conditions relevant to speech phonology or swallowing . Owing to the availability of the oral cavity to non-invasive examination, many conditions in the study of oral disease can be diagnosed, or at least suspected, from gross examination, but biopsies, cell smears, and other tissue analysis remain important diagnostic tools in oral pathology. Becoming

16206-413: The law to prosecute manufacturers for making unsupported claims of efficacy were undercut by a Supreme Court ruling restricting the federal government's enforcement powers to cases of incorrect specification of the drug's ingredients. In 1937 over 100 people died after ingesting " Elixir Sulfanilamide " manufactured by S.E. Massengill Company of Tennessee. The product was formulated in diethylene glycol ,

16352-513: The long-term health consequences of high blood pressure had not yet been established, and because they had to be administered by injection. In 1952 researchers at Ciba discovered the first orally available vasodilator, hydralazine . A major shortcoming of hydralazine monotherapy was that it lost its effectiveness over time ( tachyphylaxis ). In the mid-1950s Karl H. Beyer, James M. Sprague, John E. Baer, and Frederick C. Novello of Merck and Co. discovered and developed chlorothiazide , which remains

16498-448: The mechanisms of action for these pathogens in non-human hosts is essential to the understanding and application of epidemiology and 2) those animals that share physiological and genetic traits with humans can be used as surrogates for the study of the disease and potential treatments as well as the effects of various synthetic products. For this reason, as well as their roles as livestock and companion animals , mammals generally have

16644-499: The medieval era of Islam (see Medicine in medieval Islam ), during which numerous texts of complex pathologies were developed, also based on the Greek tradition. Even so, growth in complex understanding of disease mostly languished until knowledge and experimentation again began to proliferate in the Renaissance , Enlightenment , and Baroque eras, following the resurgence of the empirical method at new centers of scholarship. By

16790-453: The mid-1800s. By the late 1880s, German dye manufacturers had perfected the purification of individual organic compounds from tar and other mineral sources and had also established rudimentary methods in organic chemical synthesis . The development of synthetic chemical methods allowed scientists to systematically vary the structure of chemical substances, and growth in the emerging science of pharmacology expanded their ability to evaluate

16936-625: The modern Hippocratic Oath is named) having developed methods of diagnosis and prognosis for a number of diseases. The medical practices of the Romans and those of the Byzantines continued from these Greek roots, but, as with many areas of scientific inquiry, growth in understanding of medicine stagnated somewhat after the Classical Era , but continued to slowly develop throughout numerous cultures. Notably, many advances were made in

17082-524: The more popular drugs being diazepam (Valium), alprazolam (Xanax), clonazepam (Klonopin), and lorazepam (Ativan). Due to their far superior safety and therapeutic properties, benzodiazepines have largely replaced the use of barbiturates in medicine, except in certain special cases. When it was later discovered that benzodiazepines, like barbiturates, significantly lose their effectiveness and can have serious side effects when taken long-term, Heather Ashton researched benzodiazepine dependence and developed

17228-452: The most notable achievement of the period being Jonas Salk 's 1954 development of the polio vaccine under the funding of the non-profit National Foundation for Infantile Paralysis . The vaccine process was never patented but was instead given to pharmaceutical companies to manufacture as a low-cost generic . In 1960 Maurice Hilleman of Merck Sharp & Dohme identified the SV40 virus, which

17374-439: The most widely used antihypertensive drug today. This development was associated with a substantial decline in the mortality rate among people with hypertension. The inventors were recognized by a Public Health Lasker Award in 1975 for "the saving of untold thousands of lives and the alleviation of the suffering of millions of victims of hypertension". A 2009 Cochrane review concluded that thiazide antihypertensive drugs reduce

17520-462: The need for more comprehensive regulation and provided the driving force for the passage of new laws. On 12 September 1960, an American licensee, the William S. Merrell Company of Cincinnati, submitted a new drug application for Kevadon ( thalidomide ), a sedative that had been marketed in Europe since 1956. The FDA medical officer in charge of reviewing the compound, Frances Kelsey , believed that

17666-500: The other hand, often focus on a specific aspect such as discovering drug candidates or developing formulations. Often, collaborative agreements between research organizations and large pharmaceutical companies are formed to explore the potential of new drug substances. More recently, multi-nationals are increasingly relying on contract research organizations to manage drug development. Drug discovery and development are very expensive; of all compounds investigated for use in humans only

17812-429: The pH of the extract allowed a relatively pure grade of insulin to be produced. Under pressure from Toronto University and a potential patent challenge by academic scientists who had independently developed a similar purification method, an agreement was reached for non-exclusive production of insulin by multiple companies. Prior to the discovery and widespread availability of insulin therapy the life expectancy of diabetics

17958-401: The pill, and by 1965 the number had increased to 6.5 million. The availability of a convenient form of temporary contraceptive led to dramatic changes in social mores including expanding the range of lifestyle options available to women, reducing the reliance of women on men for contraceptive practice, encouraging the delay of marriage, and increasing pre-marital co-habitation. In the U.S.,

18104-518: The presence or absence of natural disease and other microscopic findings, interpretations of toxicology on body tissues and fluids to determine the chemical cause of overdoses, poisonings or other cases involving toxic agents, and examinations of physical trauma . Forensic pathology is a major component in the trans-disciplinary field of forensic science . Histopathology refers to the microscopic examination of various forms of human tissue . Specifically, in clinical medicine, histopathology refers to

18250-477: The previous 1,500 years in European medicine. With the new understanding of causative agents, physicians began to compare the characteristics of one germ's symptoms as they developed within an affected individual to another germ's characteristics and symptoms. This approach led to the foundational understanding that diseases are able to replicate themselves, and that they can have many profound and varied effects on

18396-485: The previous diagnosis. Clinical pathology is a medical specialty that is concerned with the diagnosis of disease based on the laboratory analysis of bodily fluids such as blood and urine , as well as tissues, using the tools of chemistry , clinical microbiology , hematology and molecular pathology. Clinical pathologists work in close collaboration with medical technologists , hospital administrations, and referring physicians. Clinical pathologists learn to administer

18542-645: The products of the Sanitas group are divided according to therapeutic areas: Pharmaceutical industry The pharmaceutical industry is an industry involved in medicine that discovers, develops, produces, and markets pharmaceutical goods for use as drugs that function by being administered to (or self-administered by) patients using such medications with the goal of curing or preventing disease (as well as possibly alleviating symptoms of illness or injury ). Pharmaceutical companies may deal in " generic " medications and medical devices without

18688-508: The resulting pathology report describes the histological findings and the opinion of the pathologist. In the case of cancer, this represents the tissue diagnosis required for most treatment protocols. Neuropathology is the study of disease of nervous system tissue, usually in the form of either surgical biopsies or sometimes whole brains in the case of autopsy. Neuropathology is a subspecialty of anatomic pathology, neurology , and neurosurgery . In many English-speaking countries, neuropathology

18834-486: The risk of death ( RR 0.89), stroke (RR 0.63), coronary heart disease (RR 0.84), and cardiovascular events (RR 0.70) in people with high blood pressure. In the ensuring years other classes of antihypertensive drug were developed and found wide acceptance in combination therapy, including loop diuretics (Lasix/ furosemide , Hoechst Pharmaceuticals , 1963), beta blockers ( ICI Pharmaceuticals , 1964) ACE inhibitors , and angiotensin receptor blockers . ACE inhibitors reduce

18980-479: The risk of new onset kidney disease [RR 0.71] and death [RR 0.84] in diabetic patients, irrespective of whether they have hypertension. Prior to the Second World war, birth control was prohibited in many countries, and in the United States even the discussion of contraceptive methods sometimes led to prosecution under Comstock laws . The history of the development of oral contraceptives is thus closely tied to

19126-654: The safety of the inoculation was marginal and it was not widely used. The United States recorded 206,000 cases of diphtheria in 1921, resulting in 15,520 deaths. In 1923, parallel efforts by Gaston Ramon at the Pasteur Institute and Alexander Glenny at the Wellcome Research Laboratories (later part of GlaxoSmithKline ) led to the discovery that a safer vaccine could be produced by treating diphtheria toxin with formaldehyde . In 1944, Maurice Hilleman of Squibb Pharmaceuticals developed

19272-551: The skin exist, including cutaneous eruptions (" rashes ") and neoplasms . Therefore, dermatopathologists must maintain a broad base of knowledge in clinical dermatology, and be familiar with several other specialty areas in Medicine. Forensic pathology focuses on determining the cause of death by post-mortem examination of a corpse or partial remains. An autopsy is typically performed by a coroner or medical examiner, often during criminal investigations; in this role, coroners and medical examiners are also frequently asked to confirm

19418-517: The state and function of certain tissues in the brain and heart respectively. Pathology informatics is a subfield of health informatics . It is the use of information technology in pathology. It encompasses pathology laboratory operations, data analysis, and the interpretation of pathology-related information. Key aspects of pathology informatics include: Psychopathology is the study of mental illness , particularly of severe disorders. Informed heavily by both psychology and neurology , its purpose

19564-474: The study of disease is divided into many different fields that study or diagnose markers for disease using methods and technologies particular to specific scales, organs , and tissue types. Anatomical pathology ( Commonwealth ) or anatomic pathology ( United States ) is a medical specialty that is concerned with the diagnosis of disease based on the gross , microscopic , chemical, immunologic and molecular examination of organs, tissues, and whole bodies (as in

19710-528: The symptoms produced by pancreas removal. Soon, the extract was demonstrated to work in people, but development of insulin therapy as a routine medical procedure was delayed by difficulties in producing the material in sufficient quantity and with reproducible purity. The researchers sought assistance from industrial collaborators at Eli Lilly and Co. based on the company's experience with large scale purification of biological materials. Chemist George B. Walden of Eli Lilly and Company found that careful adjustment of

19856-418: The tetracyclines (discovered at Lederle Laboratories, now a part of Pfizer ), erythromycin (discovered at Eli Lilly and Co.) and their extension to an increasingly wide range of bacterial pathogens. Streptomycin, discovered during a Merck-funded research program in Selman Waksman's laboratory at Rutgers in 1943, became the first effective treatment for tuberculosis. At the time of its discovery, sanitoriums for

20002-452: The tissue and blood analysis techniques of general pathology are of central significance to the investigation of serious infectious disease and as such inform significantly upon the fields of epidemiology , etiology , immunology , and parasitology . General pathology methods are of great importance to biomedical research into disease, wherein they are sometimes referred to as "experimental" or "investigative" pathology . Medical imaging

20148-494: The trade name Adrenalin . Injected epinephrine proved to be especially efficacious for the acute treatment of asthma attacks, and an inhaled version was sold in the United States until 2011 ( Primatene Mist ). By 1929 epinephrine had been formulated into an inhaler for use in the treatment of nasal congestion. While highly effective, the requirement for injection limited the use of epinephrine and orally active derivatives were sought. A structurally similar compound, ephedrine ,

20294-474: The vast majority of lab work and research in pathology concerns the development of disease in humans, pathology is of significance throughout the biological sciences. Two main catch-all fields exist to represent most complex organisms capable of serving as host to a pathogen or other form of disease: veterinary pathology (concerned with all non-human species of kingdom of Animalia ) and phytopathology , which studies disease in plants. Veterinary pathology covers

20440-439: Was a year of layoffs for at least 10,000 people across 129 public biotech firms globally, albeit most small firms; this was a significant increase in reductions versus 2022 was in part due to worsening global financial conditions and a reduction in investment by "generalist investors". Private firms also saw a significant reduction in venture capital investment in 2023, continuing a downward trend started in 2021, which also led to

20586-531: Was developed by Smith, Kline and French as a nasal decongestant under the trade name Benzedrine Inhaler. Amphetamine was eventually developed for the treatment of narcolepsy , post-encephalitic parkinsonism , and mood elevation in depression and other psychiatric indications. It received approval as a New and Nonofficial Remedy from the American Medical Association for these uses in 1937, and remained in common use for depression until

20732-459: Was followed in 1906 by the Pure Food and Drugs Act , which forbade the interstate distribution of adulterated or misbranded foods and drugs. A drug was considered misbranded if it contained alcohol, morphine, opium, cocaine, or any of several other potentially dangerous or addictive drugs, and if its label failed to indicate the quantity or proportion of such drugs. The government's attempts to use

20878-481: Was identified by Japanese chemists in the Ma Huang plant and marketed by Eli Lilly as an oral treatment for asthma. Following the work of Henry Dale and George Barger at Burroughs-Wellcome , academic chemist Gordon Alles synthesized amphetamine and tested it in asthma patients in 1929. The drug proved to have only modest anti-asthma effects but produced sensations of exhilaration and palpitations. Amphetamine

21024-496: Was later shown to cause tumors in many mammalian species. It was later determined that SV40 was present as a contaminant in polio vaccine lots that had been administered to 90% of the children in the United States. The contamination appears to have originated both in the original cell stock and in monkey tissue used for production. In 2004 the National Cancer Institute announced that it had concluded that SV40

21170-448: Was only a few months. The development of drugs for the treatment of infectious diseases was a major focus of early research and development efforts; in 1900, pneumonia, tuberculosis, and diarrhea were the three leading causes of death in the United States and mortality in the first year of life exceeded 10%. In 1911 arsphenamine , the first synthetic anti-infective drug, was developed by Paul Ehrlich and chemist Alfred Bertheim of

21316-535: Was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and Gerhard Domagk . This work, also based on the testing of compounds available from the German dye industry, led to the development of Prontosil , the first representative of the sulfonamide class of antibiotics . Compared to arsphenamine, the sulfonamides had a broader spectrum of activity and were far less toxic, rendering them useful for infections caused by pathogens such as streptococci . In 1939, Domagk received
