Description

 

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.

 

 

Application

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)). Phenacetin 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 phenaceti.

Phenacetin is a metabolite of phenacetiwith similar analgesic and antipyretic effects, but the new formulation has not been found to have phenacetin's carcinogenicity.

Phenacetin is now being used as a cutting agent to adulterate cocaine in the UK and Canada, owing to the similar physical features of the two drugs.

Due to low cost phenacetin is used for research into the physical and refractive properties of crystals.
Phenacetin is an ideal compound for this type of research.

 


Preparation

 

The first synthesis was reported in 1878 by Harmon Northrop Morse.

 

Phenacetin may be synthesized as an example of the Williamson ether synthesis: ethyl iodide, paracetamol, and anhydrous potassium carbonate are refluxed in 2-butanone to give the crude product, which is recrystallized from water.

Safety

 

Phenacetin, and products containing phenacetin, have been shown in an animal model to have the side effect and after-effect of carcinogenesis. In humans, many case reports have implicated products containing phenacetin in urothelial neoplasms, especially urothelial carcinoma of the renal pelvis. In one prospective series, phenacetin was associated with an increased risk of death due to urologic or renal diseases, death due to cancers, and death due to cardiovascular diseases. In addition, people with glucose-6-phosphate dehydrogenase deficiency may experience acute hemolysis, or dissolution of blood cells, while taking this drug. Acute hemolysis is possible in the case of patients who develop an IgM response to phenacetin leading to immune complexes that bind to erythrocytes in blood. The erythrocytes are then lysed when the complexes activate the complement system.

 

Chronic use of phenacetin is known to lead to analgesic nephropathy characterized by renal papillary necrosis. This is a condition which results in destruction of some or all of the renal papillae in the kidneys.

One notable death that can possibly be attributed to the use of this drug was that of the aviation pioneer Howard Hughes. He had been using phenacetin extensively for the treatment of chronic pain; it was stated during his autopsy that phenacetin use may have been the cause of his kidney failure.
