DUEXIS vs FLURBIPROFEN
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Cyclooxygenase (COX) inhibitor, reducing prostaglandin synthesis; nonsteroidal anti-inflammatory drug (NSAID) with anti-inflammatory, analgesic, and antipyretic effects.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.
Oral: 50-100 mg every 6-8 hours; maximum 300 mg/day. Ophthalmic: 1 drop every 30 minutes starting 2 hours before surgery, then 1 drop every 4-6 hours for 24-48 hours post-surgery.

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).
Terminal elimination half-life: 3-4 hours (healthy adults) in short-term use; prolonged to 6-12 hours in elderly or renal impairment.
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.
Renal: 70% as conjugated metabolites (e.g., glucuronides) and <5% unchanged; biliary/fecal: 30%, with enterohepatic circulation.
