Mechanism

Meloxicam is a preferential (but not exclusive) COX-2 inhibitor with a COX-2/COX-1 selectivity ratio of approximately 10:1. At therapeutic doses, it produces measurable inhibition of platelet thromboxane A2 production (a COX-1 function), distinguishing it from the highly selective COX-2 inhibitors (celecoxib). Its preferential selectivity provides anti-inflammatory efficacy comparable to piroxicam with reduced gastrointestinal toxicity, without completely eliminating the cardioprotective effect of low-dose aspirin. Its plasma half-life of 15-20 hours permits once-daily dosing.

Contraindications

  • patients with history of ischaemic heart disease/hypertension/cardiac failure/cerebrovascular disease (general COX-2 inhibitor precaution)

Side effects

Common
Significantly less gastric injury at 7.5 mg/day compared to piroxicam (20 mg/day), but this advantage is lost with a dosage of 15 mg/day.gastric changes (at lower dose similar to placebo; at higher dose intermediate between placebo and piroxicam)milder gastric side effects
Serious
  • Cardiovascular risk (as part of the NSAID class black-box warning)
  • ulcer complications (bleeding, perforation) on long-term use
