DUEXIS vs IBUPROHM COLD AND SINUS
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 is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis, leading to anti-inflammatory, analgesic, and antipyretic effects. Pseudoephedrine is a sympathomimetic amine that acts as a vasoconstrictor via alpha-adrenergic receptors in nasal mucosa, reducing nasal congestion.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.
1-2 tablets (each containing ibuprofen 200 mg and pseudoephedrine 30 mg) orally every 4-6 hours as needed; maximum daily dose: 6 tablets (ibuprofen 1200 mg, pseudoephedrine 180 mg).

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).
1.8–2.5 hours in adults; prolonged to 3–4 hours in elderly or hepatic impairment due to reduced clearance.
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 unchanged drug and metabolites accounts for >90% of elimination, with approximately 1% excreted as unchanged ibuprofen. Biliary/fecal excretion is <10%.
