Mechanism of Action
Parecoxib is an injectable prodrug rapidly converted into valdecoxib in the liver, which selectively inhibits COX?2, reducing prostaglandin-mediated pain and inflammation, while sparing COX?1 activity.
Research Applications & Pharmacology
-
Perioperative pain models: IV or IM administration at 20–40?mg produces rapid analgesia within 7–14 minutes and lasts up to 24 hours; comparable to ketorolac or morphine.
-
Anti-inflammatory studies: Suppresses prostaglandin synthesis, COX?2 pathways, and inflammatory mediators (e.g., IL?1?, IL?6); reduces oxidative stress and postoperative delirium in elderly models .
-
Pharmacokinetics: Parecoxib half-life ~22 min; conversion to valdecoxib with ~8?hr half?life; high protein binding (~98%); excreted primarily in urine.
Safety Profile & Handling
Reported effects:
-
Rapid analgesic onset with minimal platelet impact .
-
Typical COX?2 NSAID risks: GI ulcers, renal impairment, cardiovascular effects; dose-dependent hypotension noted .
Handling guidelines:
-
Reconstitute vial with 0.9% NaCl or 5% glucose; administer IV bolus or IM slowly and deeply; flush line before/after use .
-
Use PPE, monitor subjects for hemodynamic and renal/hepatic changes.
-
Dispose of waste as pharmaceutical hazardous material.
