Brief History of Statutory
Pharmacy Law
• In nineteenth century drugs in the United
States were unregulated
– medicines did not require proof that they were
either safe or effective
• Traveling medicine shows proclaimed
“miracle cures”
– no regulations on labeling
– no research to support claims
Need for Drug Control
• Before 1951, U.S. federal law made no
distinction between drugs that can and cannot
be purchased without a prescription from a
physician.
• In some countries any drug can still be
dispensed or sold without legal restriction.
