Early pharmacists worked in village apothecaries, purchasing chemicals in bulk and mixing them on the premises to fill prescriptions. After the Great Depression, the science of pharmacology developed and pharmaceutical companies grew rapidly, opening sophisticated research facilities. Drug patent issues grew from fewer than 100 before 1940, to over 4,000 by the 1950s. Medications began to be distributed under the manufacturer’s brand name in a final-dosage form, instead of in bulk as generic ingredients that were then combined by the pharmacist. The number of dr...
