and his student Charles Best repeated this study and found that injections of pancreatic extract reversed 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 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 was only a few months.


Early anti-infective research: Salvarsan, Prontosil, Penicillin and vaccines

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

and the selective absorption of certain dyes by bacteria, hypothesized that an arsenic-containing dye with similar selective absorption properties could be used to treat bacterial infections. Arsphenamine was prepared as part of a campaign to synthesize a series of such compounds and found to exhibit partially selective toxicity. Arsphenamine proved to be the first effective treatment for syphilis, a disease which prior to that time was 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 was pursued broadly by industrial scientists, including Bayer scientists Josef Klarer, Fritz Mietzsch, and

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 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 Second World War. Early progress toward the development of vaccines occurred throughout this period, primarily in 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

Unsafe drugs and early industry regulation

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 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 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 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 "

, 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 a drug could be sold, and explicitly prohibited false therapeutic claims.

), 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 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 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 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.

Severe cases of hypertension were treated by surgery.

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 (

Oral Contraceptives

Comstock laws The Comstock laws were a set of federal acts passed by the United States Congress under the Grant administration along with related state laws.Dennett p.9 The "parent" act (Sect. 211) was passed on March 3, 1873, as the Act for the Suppression of ...

Nonetheless, by 1962, 1.2 million American women were on 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.


Thalidomide and the Kefauver-Harris Amendments

In the U.S., 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 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 (

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 the US market. The FDA received authority to regulate advertising of prescription drugs and to establish

. The law required that all drugs introduced between 1938 and 1962 had to be effective. An FDA - National Academy of Sciences collaborative study showed that nearly 40 percent of these products were not effective. A similarly comprehensive study of over-the-counter products began ten years later.


1970–1990s


Statins

In 1971, Akira Endo, 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.

On the organisational side, big international pharma corporations have experienced a substantial decline of their value share.

Impact of Mergers and Acquisitions

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

Smaller organizations, on 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.


The cost of innovation

Drug discovery and development are very expensive; of all compounds investigated for use in humans only 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

, 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 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

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 the opportunity cost of investing capital many years before revenues are realized (see

). Because of the very long time needed for discovery, development, and approval of pharmaceuticals, these costs can accumulate to nearly half the total expense. A direct consequence within the pharmaceutical industry value chain is that major pharmaceutical multinationals tend to increasingly outsource risks related to fundamental research, which somewhat reshapes 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

A fourth phase of post-approval surveillance is also often required due to the fact that even the largest clinical trials cannot effectively predict the prevalence of rare side-effects.

Orphan drugs

There are special rules for certain rare diseases ("orphan diseases") in several major drug regulatory territories. For example, diseases involving fewer than 200,000 patients in the United States, or larger populations in certain circumstances are subject to the Orphan Drug Act. Because medical research and development of drugs to treat such diseases is financially disadvantageous, companies that do so are rewarded with tax reductions, fee waivers, and market exclusivity on that drug for a limited time (seven years), regardless of whether the drug is protected by patents.


Global sales

In 2011, global spending on prescription drugs topped $954 billion, even as growth slowed somewhat in Europe and North America. The United States accounts for more than 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

Patents and generics

Depending on a number of considerations, a company may apply for and be granted a
patent A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A ...
for the drug, or the process of producing the drug, granting exclusivity rights typically for about 20 years. However, only after rigorous study and testing, which takes 10 to 15 years on average, will governmental authorities grant permission for the company to market and sell the drug. Patent protection enables the owner of the patent to recover the costs of research and development through high profit margins for the
brand A brand is a name, term, design, symbol or any other feature that distinguishes one seller's good or service from those of other sellers. Brands are used in business, marketing, and advertising for recognition and, importantly, to create ...
ed drug. When the patent protection for the drug expires, a generic drug is usually developed and sold by a competing company. The development and approval of generics is less expensive, allowing them to be sold at a lower price. Often the owner of the branded drug will introduce a generic version before the patent expires in order to get a head start in the generic market. Restructuring has therefore become routine, driven by the patent expiration of products launched during the industry's "golden era" in the 1990s and companies' failure to develop sufficient new blockbuster products to replace lost revenues.


Prescriptions

In the U.S., the value of prescriptions increased over the period of 1995 to 2005 by 3.4 billion annually, a 61 percent increase. Retail sales of prescription drugs jumped 250 percent from $72 billion to $250 billion, while the average price of prescriptions more than doubled from $30 to $68.


Marketing

Advertising is common in healthcare journals as well as through more mainstream media routes. In some countries, notably the US, they are allowed to advertise directly to the general public. Pharmaceutical companies generally employ salespeople (often called 'drug reps' or, an older term, 'detail men') to market directly and personally to physicians and other healthcare providers. In some countries, notably the US, pharmaceutical companies also employ lobbyists to influence politicians. Marketing of prescription drugs in the US is regulated by the federal
Prescription Drug Marketing Act of 1987 {{Regulation of therapeutic goods in the United States The Prescription Drug Marketing Act (PDMA) of 1987 (P.L. 100-293, 102 Stat. 95) is a law of the United States federal government. It establishes legal safeguards for prescription drug distri ...

To healthcare professionals

The book '' Bad Pharma'' also discusses the influence of drug representatives, how ghostwriters are employed by the drug companies to write papers for academics to publish, how independent the academic journals really are, how the drug companies finance doctors' continuing education, and how patients' groups are often funded by industry.


Direct to consumer advertising

Since the 1980s, new methods of marketing for prescription drugs to consumers have become important. Direct-to-consumer media advertising was legalised in the FDA Guidance for Industry on Consumer-Directed Broadcast Advertisements.


Controversies


Drug marketing and lobbying

There has been increasing controversy surrounding pharmaceutical marketing and influence. There have been accusations and findings of influence on doctors and other health professionals through drug reps including the constant provision of marketing 'gifts' and biased information to health professionals; highly prevalent advertising in journals and conferences; funding independent healthcare organizations and health promotion campaigns; lobbying physicians and politicians (more than any other industry in the US); sponsorship of medical schools or nurse training; sponsorship of continuing educational events, with influence on the curriculum; and hiring physicians as paid consultants on medical advisory boards. Some advocacy groups, such as No Free Lunch and AllTrials, have criticized the effect of drug marketing to physicians because they say it biases physicians to prescribe the marketed drugs even when others might be cheaper or better for the patient. There have been related accusations of

In 2009, the Government-funded National Prescribing Service launched the "Finding Evidence – Recognising Hype" program, aimed at educating GPs on methods for independent drug analysis. Meta-analyses have shown that psychiatric studies sponsored by pharmaceutical companies are several times more likely to report positive results, and if a drug company employee is involved the effect is even larger. Influence has also extended to the training of doctors and nurses in medical schools, which is being fought. It has been argued that the design of the Diagnostic and Statistical Manual of Mental Disorders and the expansion of the criteria represents an increasing medicalization of human nature, or "

The potential for direct conflict of interest has been raised, partly because roughly half the authors who selected and defined the DSM-IV psychiatric disorders had or previously had financial relationships with the pharmaceutical industry.

Data are made public in the Centers for Medicare & Medicaid Services website. The expectation is that relationship between doctors and Pharmaceutical industry will become fully transparent.

(FDA) in the United States – advance the interests of the drug companies rather than the interests of the public due to revolving door exchange of employees between the regulator and the companies and friendships develop between regulator and company employees. He argues that regulators do not require that new drugs offer an improvement over what is already available, or even that they be particularly effective. Others have argued that excessive regulation suppresses therapeutic innovation and that the current cost of regulator-required clinical trials prevents the full exploitation of new genetic and biological knowledge for the treatment of human disease. A 2012 report by the President's Council of Advisors on Science and Technology made several key recommendations to reduce regulatory burdens to new drug development, including 1) expanding the FDA's use of accelerated approval processes, 2) creating an expedited approval pathway for drugs intended for use in narrowly defined populations, and 3) undertaking pilot projects designed to evaluate the feasibility of a new, adaptive drug approval process.

Response to COVID-19

In November 2020 several pharmaceutical companies announced successful trials of COVID-19 vaccines, with efficacy of 90 to 95% in preventing infection. Per company announcements and data reviewed by external analysts, these vaccines are priced at $3 to $37 per dose. The Wall Street Journal ran an editorial calling for this achievement to be recognized with a Nobel Peace Prize.

On 20 February, 46 US lawmakers called for the US government not to grant monopoly rights when giving out taxpayer development money for any coronavirus vaccines and treatments, to avoid giving exclusive control of prices and availability to private manufacturers. In the United States the government signed agreements in which research and development and/or the building of manufacturing plants for potential COVID-19 therapeutics was subsidized. Typically, the agreement involved the government taking ownership of a certain number of doses of the product without further payment. For example, under the auspices of Operation Warp Speed in the United States, the government subsidized research related to COVID-19 vaccines and therapeutics at Regeneron, Johnson and Johnson, Moderna, AstraZeneca, Novavax, Pfizer, and GSK. Typical terms involved research subsidies of $400 million to $2 billion, and included government ownership of the first 100 million doses of any COVID-19 vaccine successfully developed.

In May 2020, Gilead announced that it would provide the first 940,000 doses of remdesivir to the federal government free of charge. After facing strong public reactions, Gilead gave up the "orphan drug" status for remdesivir on 25 March. Gilead retains 20-year remdesivir patents in more than 70 countries. In May 2020, the company further announced that it was in discussions with several generics companies to provide rights to produce remdesivir for developing countries, and with the Medicines Patent Pool to provide broader generic access.

in South Africa, and ARVs at the time cost between US$10,000 and US$15,000 per patient per year. This was unaffordable for most South African citizens, and so the South African government committed to providing ARVs at prices closer to what people could afford. To do so, they would need to ignore the patents on drugs and produce generics within the country (using a compulsory license), or import them from abroad. After international protest in favour of public health rights (including the collection of 250,000 signatures by

), the governments of several developed countries (including The Netherlands, Germany, France, and later the US) backed the South African government, and the case was dropped in April of that year. In 2016, GlaxoSmithKline (the world's sixth largest pharmaceutical company) announced that it would be dropping its patents in poor countries so as to allow independent companies to make and sell versions of its drugs in those areas, thereby widening the public access to them. GlaxoSmithKline published a list of 50 countries they would no longer hold patents in, affecting one billion people worldwide.
