coxib

(kok'ib),
Shortened colloquial name for the cyclooxygenase-2 inhibitors; all members of that groups' names end in the suffix "coxib."

coxib

(kŏk′sĭb)
Any nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation by inhibiting cyclooxygenase-2 (COX-2) but not cyclooxygenase-1 (COX-1). Most NSAIDs (e.g., celecoxib) inhibit both COX-2 and COX-1. Selective inhibition prevents the coxibs from forming prostaglandins, which irritate the upper gastrointestinal tract.
