What is "zomepirac"

n. A particular nonsteroidal anti-inflammatory drug with antipyretic action, withdrawn in the 1980s because of the risk of anaphylaxis.

Zomepirac is an orally effective non-steroidal anti-inflammatory drug (NSAID) that has antipyretic actions. It was developed by McNeil Pharmaceutical and approved by the FDA in 1980 and sold as the sodium salt, zomepirac sodium, under the brand name Zomax. Due to its clinical effectiveness, it was preferred by doctors in many situations and obtained a large share of the analgesics market; however, it was subsequently withdrawn in March 1983 due to its tendency to cause serious anaphylaxis in an unpredictable subset of the patient population.
