INTRODUCTION:
America's Pharmaceutical Founding Fathers:
The mid-19th century marked a significant period of growth for the pharmaceutical industry in the United States. Pfizer, founded in 1849 by German immigrants, began as a fine chemicals company. The demand for medical supplies, such as painkillers and antiseptics, surged during the American Civil War, leading to rapid expansion for Pfizer.
Among those serving in the Union Army was Colonel Eli Lilly, a trained pharmaceutical chemist. After his military service, Lilly's diverse talents led him to establish his own pharmaceutical company in 1876, emphasizing innovation in research and production.
Edward Robinson Squibb, another notable figure, served as a naval doctor during the Mexican-American War. Dissatisfied with the quality of medical supplies, Squibb took matters into his own hands by founding a laboratory in 1858. His lab provided high-quality drugs to the Union forces during the Civil War, eventually forming the foundation of Bristol-Myers Squibb.
Switzerland's Pharmaceutical Evolution:
Switzerland experienced rapid development in its pharmaceutical industry during the latter half of the 19th century. Initially prominent in the textile and dye industries, Swiss manufacturers discovered the medicinal properties of their dyes. This shift led them to market these products as medicines, a significant departure from the origins of many pharmaceutical businesses. The lack of patent laws in Switzerland at the time sparked controversy, with accusations from Germany labeling Switzerland as a "pirate state." This period saw the emergence of major companies like Sandoz, CIBA-Geigy, and Roche, all rooted in Basel.
The Early 1900s: The Rise of Aspirin:
The transition from the 19th to the 20th century brought further advancements. Bayer, originally a dye manufacturer established in 1863, made a groundbreaking move into pharmaceuticals with the commercialization of aspirin. This product became one of the most successful drugs in history. During this time, the distinction between the pharmaceutical and chemical industries was less pronounced than today. Companies produced various items, including medical and non-medical products, under one roof.
The impact of global conflicts also played a role in shaping the industry. After World War I, many Swiss pharmaceutical companies relocated their production facilities abroad, including to the United States, to navigate the changing economic and political landscape.

Disruptions and Globalization in the Early 20th Century:
In the early 20th century, significant geopolitical events profoundly impacted the pharmaceutical industry. During World War I, Bayer's aspirin trademark and its assets in the United States were seized. Simultaneously, "American" Merck (now known as Merck & Co. in the US and Merck Sharp & Dohme (MSD) elsewhere) was separated from its German parent company, Merck KGaA. Bayer's subsidiary in Russia was also confiscated during the Russian Revolution.
These disruptions weakened Germany's dominance in the pharmaceutical sector, providing opportunities for other countries, particularly the United States, to gain a comparative advantage. This period marked the early stages of industrial globalization, as seen both before and after the war. In the United Kingdom, import tariffs encouraged many foreign companies, such as Wyeth, Sandoz, CIBA, Eli Lilly, and MSD, to establish subsidiaries in Britain during the post-war era.3
During the interwar period from 1918 to 1939, two transformative breakthroughs reshaped the pharmaceutical landscape. First, the discovery of insulin by Frederick Banting and colleagues provided a life-saving treatment for diabetes, previously a fatal illness. Collaboration with Eli Lilly enabled the large-scale production and distribution of insulin, revolutionizing diabetes care.
The second breakthrough was penicillin, discovered by Alexander Fleming in 1928 for its antibiotic properties. Further research by Howard Florey and Ernst Chain led to its mass production during World War II, supported by governments and pharmaceutical companies like Merck, Pfizer, and Squibb, which significantly reduced mortality rates among soldiers.
After World War II, the pharmaceutical industry flourished, particularly in the US, buoyed by substantial government funding and economic growth. The establishment of healthcare systems such as Britain's National Health Service (NHS) provided structured frameworks for drug prescribing and payment, facilitating continued industry expansion.
However, ethical concerns emerged as the industry grew. George Merck, in 1950, emphasized medicine's primary purpose as serving people rather than profit, reflecting ongoing debates about balancing public health and commercial interests. Increased government regulations on pharmaceuticals on both sides of the Atlantic aimed to ensure drug safety and ethical standards amid industry growth.

The Thalidomide scandal in 1961 was a watershed moment that prompted significant advancements in drug safety regulation and monitoring. Following this tragedy, the US Food and Drug Administration (FDA) introduced the Kefauver-Harris Amendment in 1962, mandating rigorous testing for drug efficacy and accurate disclosure of side effects before approval. Similarly, the 1964 Declaration of Helsinki established stringent ethical guidelines for clinical research, clarifying the distinction between medicinal drugs and other chemical substances used in scientific practice. These developments marked crucial steps towards enhancing public safety and ethical standards in pharmaceutical research and production.

The FDA's pivotal role during the Thalidomide crisis was exemplified by Frances O. Kelsey, whose refusal to approve Thalidomide prevented thousands of children from being born with severe deformities. This event underscored the need for stricter drug safety regulations, leading to the implementation of the Kefauver-Harris Amendment in 1962. This amendment mandated rigorous testing for drug efficacy and the accurate disclosure of side effects before approval, marking a significant shift towards ensuring public safety in pharmaceuticals.
The post-war era witnessed a "golden age" of drug development, characterized by advancements driven by enhanced manufacturing methods and deeper biological understanding. This period, spanning from the 1940s to the early 1970s, saw substantial improvements in living standards and technological optimism amidst Cold War scientific competition. The pharmaceutical industry expanded globally, with companies like Pfizer establishing subsidiaries across multiple countries.
Notable drugs from this era included the revolutionary birth control pill introduced in 1960, which transformed societal norms by empowering women to control fertility. Additionally, medications like Valium (diazepam), MAOIs, and Haloperidol significantly advanced psychiatric treatment, complementing traditional psychoanalytic approaches.
The 1970s marked a surge in cancer research spurred by the US government's "war on cancer," resulting in the development of effective cancer drugs that substantially improved survival rates. Drugs like ACE inhibitors, paracetamol, and ibuprofen also became widely available during this period, further shaping modern pharmaceutical practice.
By the late 1970s, the industry shifted focus towards developing blockbuster drugs, exemplified by Tagamet, the first drug to exceed $1 billion in annual sales. Innovations continued with the introduction of Prozac in 1987, the first SSRI, and the approval of statins for heart health.
Entering the 21st century, advancements in genetics and biotechnology have fueled the development of biologics, gene therapies, and immuno therapies. These innovations hold promise for treating previously untreatable conditions and have led to breakthroughs in cancer care, exemplified by drugs like Keytruda and CAR-T therapies.
In infectious diseases, ongoing advancements offer hope for eradicating conditions like hepatitis C through effective pharmaceutical interventions. This ongoing evolution underscores the pharmaceutical industry's commitment to innovation and improving global health outcomes.
In 2020, the pharmaceutical industry made unprecedented strides in developing numerous potential vaccines against the COVID-19 pandemic at an accelerated pace, responding to the urgent global crisis posed by the novel corona virus.
However, these advancements have not been without challenges. The cost of these new drugs has strained healthcare system finances and pushed the boundaries of scientific and technological capabilities. For instance, Gilead faced significant scrutiny over the initial pricing of its hepatitis C therapies, although prices have since decreased as more competitors entered the market. Similarly, firms like Vertex have encountered prolonged disputes over pricing for new cystic fibrosis treatments, particularly in countries like the UK where payers have stringent requirements.
Despite progress in many areas, research into new antibiotics has stagnated due to financial disincentives for large pharmaceutical companies. This stagnation is occurring at a critical time when antimicrobial resistance poses a growing threat to global health security.
Looking ahead, while the future holds promise for continued innovation in the pharmaceutical industry, maintaining public trust and addressing challenges like antimicrobial resistance will be crucial priorities throughout the 21st century. These efforts will be essential in preventing millions of deaths from antibiotic-resistant infections and ensuring sustainable healthcare advancements globally.
