Effects of meloxicam on platelet function in healthy adults: a randomized, double-blind, placebo-controlled trial.

Nonsteroidal anti-inflammatory drugs (NSAIDs) inhibit cyclooxygenase-1 (COX-1), thereby inhibiting platelet function via blockade of thromboxane A2 (TxA2) formation, and COX-2, the enzyme that mediates inflammatory responses. Meloxicam is a relatively COX-2-selective anti-arthritis drug that shows significant TxA2 inhibition, albeit less than traditional NSAIDs. A randomized, double-blind, placebo-controlled trial was conducted in 79 healthy adults to compare the effects of once-daily therapeutic (7.
