DUEXIS vs LODINE XL
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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis leading to anti-inflammatory, analgesic, and antipyretic effects.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.
400 mg or 600 mg orally once daily.

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 is approximately 6-7 hours. Steady-state is achieved within 2 days.
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 excretion of metabolites accounts for approximately 70% of a dose; fecal excretion accounts for about 20%.
