DUEXIS vs IBUPROFEN LYSINE
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.
Ibuprofen lysine is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This results in anti-inflammatory, analgesic, and antipyretic effects.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.
200-800 mg orally every 6-8 hours as needed; maximum 2400 mg/day. Intravenous: 400-800 mg every 6 hours; maximum 3.2 g/day.

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).
2–4 hours in adults; extended to 4–6 hours in neonates. In severe hepatic or renal impairment, half-life may increase up to 8–10 hours.
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 and conjugates accounts for >90% of elimination; less than 1% is excreted unchanged in urine. Fecal excretion is minimal (<5%).
