Application
Rofecoxib: A Selective Cyclooxygenase-2 (COX-2) Inhibitor
Rofecoxib is a non-steroidal anti-inflammatory drug (NSAID), and a selective cyclooxygenase-2 (COX-2) inhibitor. The mechanism of action is mainly by inhibition of the enzyme COX in the arachidonic acid metabolism pathway, resulting in reduced prostaglandin synthesis. In theory, a drug that selectively inhibited COX-2 might block inflammation, pain, and fever produced by prostaglandins while reducing the side effects (gastric erosions and ulcers) associated with inhibition of COX-1. For your reference, rofecoxib was withdrawn from the medicine market in 2004 after it was shown that long-term clinical use could increase the risk of heart attack and stroke. (The product is for research purpose only.)
