COX
Cyclooxygenase (COX) is an enzyme (specifically, a family of isozymes) that is responsible for formation of prostanoids, including thromboxane and prostaglandins such as prostacyclin. Pharmaceutical inhibition of COX can provide relief from the symptoms of inflammation and pain. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, exert their effects through inhibition of COX. The two isozymes found in human are called COX-1 and COX-2 in the medical literature.
