COXANTO vs IBUPROFEN AND DIPHENHYDRAMINE CITRATE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective inhibitor of soluble epoxide hydrolase (sEH), increasing levels of epoxyeicosatrienoic acids (EETs), which have vasodilatory, anti-inflammatory, and antifibrotic effects.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby decreasing pain, fever, and inflammation. Diphenhydramine citrate is an antihistamine that antagonizes histamine H1 receptors, producing sedative and anticholinergic effects.
1 g intravenous every 6 hours.
Ibuprofen 200 mg + Diphenhydramine citrate 38 mg (equivalent to diphenhydramine HCl 25 mg) orally every 4-6 hours as needed, not to exceed Ibuprofen 1200 mg/day or Diphenhydramine citrate 152 mg/day.

Terminal elimination half-life: 12-15 hours (prolonged to 24-30 hours in moderate-to-severe renal impairment, requiring dose adjustment)
Ibuprofen: terminal elimination half-life approximately 1.8-2.5 hours in adults; prolonged in elderly and patients with hepatic impairment. Diphenhydramine: terminal elimination half-life ranges from 4 to 10 hours (mean 7 hours); may be prolonged in elderly and hepatic impairment.
Renal: 70% unchanged; biliary/fecal: 20% as metabolites; 10% other
Ibuprofen: renal elimination of metabolites (approximately 90%) and unchanged drug (approximately 10%); fecal elimination <5%. Diphenhydramine: primarily renal elimination (approximately 60-70% as metabolites, 1-2% unchanged); fecal elimination approximately 10-15%.
