CategoriesMedical

COX-2 stands for Cyclooxygenase-2 selective inhibitor, a drug class abbreviation.

NSAIDs that preferentially block the COX-2 enzyme involved in inflammation while sparing COX-1, which protects the stomach lining. Celecoxib (Celebrex) is the only one still sold in the US.

Example: Hx GI bleed: COX-2 inhibitor celecoxib 100 mg BID plus PPI for hip OA.

Usage notes

Rofecoxib (Vioxx) was withdrawn worldwide in 2004 after a trial showed an increased risk of heart attacks and strokes, and valdecoxib followed in 2005. The PRECISION trial (2016) found celecoxib at moderate doses no riskier for the heart than ibuprofen or naproxen. Often written "COX-2 inhibitor" or "coxib".
