CLINORIL vs DUEXIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, thereby exerting anti-inflammatory, analgesic, and antipyretic effects. Sulindac is a prodrug converted to the active sulfide metabolite.
DUEXIS is a combination of ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, and famotidine, a histamine H2-receptor antagonist that decreases gastric acid secretion. Famotidine mitigates the risk of NSAID-induced gastric ulcers.
150-200 mg orally twice daily, with maximum daily dose of 400 mg.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.

7.8 hours (terminal); clinical context: prolonged in elderly and renal impairment, requiring dose adjustment.
Ibuprofen: 2-4 hours (terminal); requires every 6-8 hour dosing. Famotidine: 2.5-3.5 hours (normal renal function); prolonged to 20 hours or more in severe renal impairment (CrCl < 30 mL/min).
Renal: 50% as unchanged drug, 25% as glucuronide conjugate; Biliary/Fecal: 25% as metabolites.
Ibuprofen: ~1% unchanged in urine, 14% as conjugated metabolites, remainder as oxidative metabolites; <1% excreted in feces. Famotidine: 65-70% unchanged in urine, 30-35% metabolized hepatic; <10% fecal.
