Uses:
Phenacetin was widely used until the third quarter of the twentieth century, often in the form of an "A.P.C." or aspirin-phenacetin-caffeine compound analgesic, as a remedy for fever and pain. An early formulation (1919) was Vincent's APC in Australia. However the U.S. Food and Drug Administration ordered the withdrawal of drugs containing phenacetin in November 1983, owing to its carcinogenic and kidney-damaging properties (Federal Register of October 5, 1983 (48 FR 45466)). It was also banned in India.As a result some branded, previously phenacetin-based preparations continued to be sold, but with the phenacetin replaced by safer alternatives. A popular brand of phenacetin was Roche's Saridon, which was reformulated in 1983 to contain propyphenazone, paracetamol and caffeine. Coricidin was also reformulated without phenacetin. Paracetamol is a metabolite of phenacetin with similar analgesic and antipyretic effects, but the new formulation has not been found to have phenacetin's carcinogenicity.
