ANJESO vs DUEXIS
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-steroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby decreasing inflammation and pain.
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.
120 mg administered intravenously over 15 minutes, followed by 30 mg intravenously over 15 minutes, with the second dose given 12 to 24 hours after the first dose.
One tablet (800 mg ibuprofen/26.6 mg famotidine) orally three times daily.

Terminal elimination half-life is 1.5-2.5 hours in healthy adults. In elderly or renally impaired patients, half-life may extend to up to 6 hours.
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).
Approximately 70% renal (30% unchanged, 40% as glucuronide conjugate), 30% fecal/biliary.
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.
