Description
Sources: https://www.ncbi.nlm.nih.gov/books/NBK304337
Curator's Comment: Description was created based on several sources, including https://www.ncbi.nlm.nih.gov/pubmed/18140117 | https://www.ncbi.nlm.nih.gov/pubmed/3552585 | https://www.ncbi.nlm.nih.gov/pubmed/12242329 | https://www.ncbi.nlm.nih.gov/pubmed/14592552

Phenacetin was used as an analgesic and fever-reducing drug in both human and veterinary medicine for many years. Since a major portion of a dose of phenacetin is rapidly metabolised to paracetamol, it seems possible that phenacetin owes some of its therapeutic activity to its main metabolite, paracetamol, whereas its most troublesome side effect (methaemoglobinaemia) is due to another metabolite, p-phenetidine. Phenacetin was shown to inhibit cyclooxygenase (COX)-3, a cyclooxygenase-1 variant while p-phenetidine potently inhibits both COX-1 and COX-2. There is sufficient evidence in humans for the carcinogenicity of analgesic mixtures containing phenacetin. Analgesic mixtures containing phenacetin cause cancer of the renal pelvis, and of the ureter. Phenacetin was withdrawn from many analgesic mixtures long before the legal ban in several countries.

Sample Use Guides

In Vivo Use Guide

Analgesic mixtures containing phenacetin were previously marketed as tablets or capsules containing between 150 and 300 mg phenacetin. Common combinations were: 150 mg phenacetin, 230 mg aspirin, and 15 or 30 mg caffeine; or 150 mg phenacetin, 230 mg aspirin, 30 mg caffeine, and 8, 15, 30, or 60 mg codeine phosphate. Phenacetin alone was also available in 250 and 300 mg doses as tablets, and up to 500 mg doses as powder. The usual dose was 300 mg 4–6 times per day, and the daily dose was not to exceed 2 g
