Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis. Diphenhydramine is an antihistamine that antagonizes histamine H1 receptors.
Oral: 300-600 mg every 6-8 hours as needed; maximum 3200 mg/day.
1-2 tablets (200 mg ibuprofen/25 mg diphenhydramine HCl each) orally every 4-6 hours as needed; maximum 6 tablets in 24 hours.

Terminal elimination half-life is 2–3 hours; may be prolonged in elderly and patients with hepatic impairment.
Ibuprofen: 2-4 hours (immediate-release). Diphenhydramine: 8-12 hours (prolonged in hepatic impairment).
Primarily renal; approximately 90% of a dose is excreted in urine as glucuronide conjugates and unchanged drug; <2% excreted in feces.
Ibuprofen: Renal (90% as glucuronide conjugates, <10% unchanged). Diphenhydramine: Renal (primarily as metabolites, <10% unchanged). Both undergo hepatic metabolism with renal excretion of metabolites.
