Coca and cocaine as medicines: an historical review

Coca has been used in folk medicine in South America for thousands of years both as a general stimulant and for more specific medical purposes. It remains one of the most commonly used medicines in some areas of Bolivia and Peru. The medical use of coca and cocaine in the industrial world has a more dramatic and varied history. Coca extract and cocaine were introduced as pancreas for a wide variety of complaints in the late 19th century. Cocaine was the first effective local anesthetic; prescription drugs, patent medicine, and soda drinks containing it were also popular. When its dangers became apparent and substitutes became available, its medical use went into decline, especially when, in the 1930s, amphetamine began to replace it for some purposes. Today its only generally accepted medical use is as a topical anesthetic in certain kinds of minor surgery and other clinical procedures. There are, however, some recent and so far uncertain signs of reviving interest in cocaine and even coca itself for other medical purposes, in research as well as in diagnosis and treatment.
