Short-term management of acute postoperative pain
Max Dose
80 mg/day
Half-life
22 mins (Act: 8h)
CV Risk
HIGH RISK
Renal Risk
MODERATE
Overview
The only injectable highly selective COX-2 inhibitor. An absolute powerhouse for post-operative multimodal analgesia, sparing the gut while heavily sparing opioid use.
Maximum Dose
Max 80 mg/day (e.g., 40 mg BD).
Clinical Focus
It is a prodrug that rapidly converts to valdecoxib. Carries the same severe cardiovascular and renal risks as all NSAIDs. Do not use post-CABG.
Bottom Line
Parecoxib is the only injectable COX-2 inhibitor for acute post-operative pain, but carries cardiovascular risk with prolonged use and is contraindicated after CABG surgery.
