Cyclooxygenase-2 inhibitor
Cyclooxygenase-2 inhibitors (COX-2 inhibitors; also known as coxibs) are a type of nonsteroidal anti-inflammatory drug (NSAID) that directly target cyclooxygenase-2 (COX-2), an enzyme responsible for inflammation and pain. Targeting selectivity for COX-2 reduces the risk of peptic ulceration and is the main feature of celecoxib, rofecoxib, and other members of this drug class.
