Cures
• Rabies vaccine, 1888
• Diphtheria antitoxin, 1891: concept of stimulating
immune system
• Salvarsan, 1907 – 606: concept of toxic receptors
• Insulin, 1921, addition of normal bodily
substances
• Sulphanilimide, 1935, penicillin, 1941,
streptomycin, 1944: antibacterial agents
• Corticosteroids, 1948
The emergence of clinical
“SCIENCE”
• The Paris Hospitals, early 19th century
• PCA Louis and the numerical method, 1830s1840s

– Hospital as an experimental site
– Very large (tractable) patient populations
– Bleeding does not improve pneumonia
• Karl Pearson (1857-1936)
– Mathematics of correlation and regression

• Raymond Pearl (1879-1940)
– Application of Pearsonian statistics in
medicine, 1940s

The pharmaceutical industry
• Pharmacopeias: lists of recognized
medicaments (and modes of preparation):
Problems of strength

11th century Arabia
1618: London Royal College of Physicians
1820: U.S. Pharmacopeia
1888: National Formulary
1906, 1938: accepted as legal standards
• www.usp.org
• Proprietaries: Hamlin’s Wizard oil
• "Rheumatism, toothache, deafness, burns,
bites of dog, quinsy, diphtheria, gastralgia,
cholera morbus, bleeding gums,... and just
about everything else!"
• Ethicals: laudanum

Regulation of the pharmaceutical
industry
• Federal Pure Food and Drugs Act, 1906 (the Wiley Act), section 8,
Mislabeling In the case of drugs”
– FIRST. If it be an imitation of or offered for sale under the name of
another article.
– SECOND. If the contents of the package as originally put up shall have
been removed, in whole or in part, and other contents shall have been
placed in such package, or if the package fail to bear a statement on the
label of the quantity or proportion of any alcohol, morphine, opium,
cocaine, heroin, alpha or beta eucaine, chloroform, cannabis indica,
chloral hydrate, or acetanilide, or any derivative or preparation of any
such substances contained therein.
• Problems: Pinkham’s vegetable tonic (20% alcohol)
• Amendment 1912 allows action against “false and fraudulent” claims

Empirical age of pharmacology (to
mid 1950s)
•
•
•
•
Lots of new compounds; interest in families of compounds
Assumption of structural molecular specificity
Little knowledge of HOW drugs work
Drug testing in the 1930s
– Safety, but new uses and combinations
• Rasmussen’s classes
– Free-lancers: established clinical scientists
– Efficient: wannabe clinical scientists: practitioners with access to
patients
– Friendly experts: the insidious “general consultant”
Regulation of the pharmaceutical
industry/2
• 1937 Sulfanilamide incident:
• Elixir Sulfanilamide: sulfanilamide +
diethylene glycol + raspberry flavoring
• 100 deaths:
• Defense
• "We have been supplying a legitimate
professional demand and not once could have
foreseen the unlooked-for results. I do not feel
that there was any responsibility on our part.“
• Fined, under 1906 act for mislabeling
(elixir = alcohol)[

Regulation of the pharmaceutical
industry/3
• Leads to passage of Foods, Drugs, and
Cosmetic Act, 1938, est. FDA
– Amendments, 1940s, to 1951:
• lead to prescription-only drugs after 1951
• Requirements for pre-approval testing
• Medical Advertising
– After 1951, to gatekeeper physicians
– After 1980s, to public
• Back to consumer medicine
It’s my body: why not let me
choose?
• Problem of drugs; diagnostic techniques
–
–
–
–
Efficacy, 1962, enforced after 1970
False positives and negatives
Risk (or tolerance)-benefit ratio
Presumption of universal human
• State interests in citizenry vs therapeutic
liberty
– Ecological interests – veterinary antibiotic use
• Inability to choose
– OTC vs prescription
Controlled trials (and epidemiology)
• 1. Diagnostic accuracy
– Disease + patient + stage
• 2. Meaningful control
• 3. Elimination of bias
ideally double blind
• 4. agreed measures of
success
• 5. Meaningful long-term
follow-up
• Problematic before
serology: large numbers
mask
• Complicated conceptually
in epidemiology and
ethically in treatment trials
• Presumes biomedical
model of cure
• Requires standardized
modes of measurement
• Requires enormous
commitment of social
workers, statisticians:
Even necessary?
The concept of clinical trials
• Arrowsmith’s trials of plague antidote: St. Hubert
– Gottlieb’s instruction: follow the Protocol
– Sondelius’ capitulation: follow Gottlieb
– Arrowsmith’s capitulation: save lives, sacrifice
science
• The Reception of Arrowsmith: science is a hard but
noble master
Federal funding of medical
research

– Rockefeller Foundation
• Rockefeller Institute, New York
