DUEXIS vs DYLOJECT
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-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.
50 mg intramuscularly every 6 hours as needed for pain; maximum 150 mg per 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 (terminal) in adults; prolonged in elderly (up to 6-8 hours) and hepatic impairment (up to 12 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: ~50% as unchanged drug and metabolites (glucuronide conjugates); Biliary/fecal: ~40% as metabolites; <5% unchanged in feces.
