penacetin is a synthetic, white crystalline solid that is slightly soluble in water and benzene, soluble in acetone and very soluble in pyrimidine. It is used in research as the preferred marker for detecting CYP1A2-based inhibition potential in vitro. Human ingestion of phenacetin can result in a bluish discoloration of the skin due to a lack of oxygen in the blood (cyanosis), dizziness and respiratory depression. It is reasonably anticipated to be a human carcinogen.
The painkiller phenacetin was the world's first synthetic pharmaceutical drug. It was developed by an American chemist and began distribution in 1887. Phenacetin was often accompanied by aspirin and caffeine in what were called APC pills, which were widely distributed during and after World War II. The use of phenacetin in the U.S. was discontinued in the 1980s because of links to cancer and other adverse side effects, but it remains available in some countries.
Phenacetin is a white crystalline powder with the chemical composition C10H13NO2. It was first developed by Harmon Northrop Morse in 1878. In addition to its pain-reducing properties, it also has been used as a fever-reducer, a treatment for rheumatoid arthritis and a treatment for intercostal neuralgia, a rare disorder that causes pain in the nerves around the ribs. It was one of the first painkillers that was not derived from opium while at the same time being absent of anti-inflammatory qualities.
In 1983, the U.S. Food and Drug Administration (FDA) banned phenacetin in the U.S. because of its discovered carcinogenic properties and its link to kidney failure. The FDA stated that phenacetin alone is reasonably believed to be a human carcinogen, or cancer-causing agent, and that painkiller mixtures containing the drug are known human carcinogens. There has been little evidence found that phenacetin alone is a human carcinogen because it usually has been administered in combination with other drugs.
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.
