Mechanism of action

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