IBUPROFEN AND DIPHENHYDRAMINE HYDROCHLORIDE vs LODINE XL
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), reducing prostaglandin synthesis leading to anti-inflammatory, analgesic, and antipyretic effects.
1-2 tablets (200 mg ibuprofen/25 mg diphenhydramine HCl each) orally every 4-6 hours as needed; maximum 6 tablets in 24 hours.
400 mg or 600 mg orally once daily.

Ibuprofen: 2-4 hours (immediate-release). Diphenhydramine: 8-12 hours (prolonged in hepatic impairment).
Terminal elimination half-life is approximately 6-7 hours. Steady-state is achieved within 2 days.
Ibuprofen: Renal (90% as glucuronide conjugates, <10% unchanged). Diphenhydramine: Renal (primarily as metabolites, <10% unchanged). Both undergo hepatic metabolism with renal excretion of metabolites.
Renal excretion of metabolites accounts for approximately 70% of a dose; fecal excretion accounts for about 20%.
