ANJESO vs IBUPROFEN AND DIPHENHYDRAMINE CITRATE
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.
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.
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.
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 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: 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.
Approximately 70% renal (30% unchanged, 40% as glucuronide conjugate), 30% fecal/biliary.
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%.
