Aug 6, 2024

Lecture Notes: Birth of the Modern Pharmaceutical Industry

Introduction

  • Previous lecture focused on the birth of microbiology.
  • Discussed William Perkin's accidental discovery of synthetic dyes leading to modern pharmaceutical companies.

Evolution of Dyestuff Companies to Pharmaceuticals

  • Farbwerke Höchst
    • Founded in 1863 in Höchst, now part of Frankfurt, Germany.
    • Expanded workforce to over 2,000.
    • Shifted focus to synthetic drugs in late 19th century.
    • Launched two analgesics: antipyrine and amidopyrine (1888-1889).
    • Marked a paradigm shift towards synthetic chemistry in pharmaceuticals.

Development of Tablets

  • Machinery for tablet compression developed in France around 1860.
  • Tablets combined drugs with excipients for better consumption.

Anaesthetics: Historical Context

  • Pain relief was minimal throughout history.
  • Early anaesthetic substances:
    • Poppy extracts - Sumerians, 6,000 years ago.
    • Hemp smoke - Introduced by Indian surgeon Sushruta, 600 BCE.
    • Roman mixtures - Alcohol and herbs like opium, mandrake, henbane, and hemlock.
    • Cocaine - Known since the 14th century through the Inca civilization.
    • Ether and chloroform - Introduced by Paracelsus in the 16th century.
    • Nitrous oxide - Short duration but effective.
  • Modern anaesthetics developed through organic synthesis.
  • Novocain (Procaine) introduced by Höchst in 1905; successful in dental procedures.

Growth of Höchst and Bayer

  • Höchst's Growth

    • By 1913, 9,000 workers, $100 million turnover.
    • Factories across Europe, including Russia, France, UK.
    • Significant investment in R&D.
  • Bayer

    • Founded in 1863 near Wuppertal, initially in the dye business.
    • Entered pharmaceuticals around 1880, introduced phenacetin (analgesic).
    • Created modern Leverkusen city, now with 160,000 residents.
    • Famous for Aspirin (1898): anti-inflammatory properties; mechanism discovered in 1971.
    • Most widely used drug globally (40,000 metric tons/year).

Controversial Drug Introductions

  • Heroin (1898) - Morphine derivative, initially sold as a cough suppressant; later revealed to be addictive.
  • Barbiturates - First introduced in the early 20th century.
    • Barbituric acid synthesized in 1864.
    • Veronal (1904) marketed by Bayer; replaced bromide for insomnia but caused tolerance and abuse.

E. Merck: A Different Origin

  • Founded as a pharmacy in 1668 in Darmstadt.
  • Focused on natural products, including important alkaloids.
  • Notable product: Oxycodone (Eukodal) - synthetic opioid with addictive potential.

Impact of World War I

  • Significant shift in global pharmaceutical landscape.
  • Allied countries ceased imports of German products; local branches were shut down.
  • US revoked German patents, allowing local production.
  • US pharma industry began to grow rapidly post-war.
  • German pharma companies faced economic ruin; US Merck separated from E. Merck Darmstadt.

Conclusion

  • Despite challenges, the German pharmaceutical industry eventually led to the antibiotic revolution.
