Mechanism of action

As a selective COX-2 inhibitor, valdecoxib preferentially blocks COX-2 enzyme activity over COX-1, thereby reducing inflammatory prostaglandins while theoretically sparing the protective prostaglandins produced by COX-1 in the gastrointestinal tract and platelets. This selectivity was intended to provide anti-inflammatory and analgesic benefits with a reduced risk of gastrointestinal ulceration compared to non-selective NSAIDs.
