DYLOJECT vs IBUPROFEN AND DIPHENHYDRAMINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing prostaglandin synthesis, which mediates inflammation, pain, and fever.
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.
50 mg intramuscularly every 6 hours as needed for pain; maximum 150 mg per 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.

2-4 hours (terminal) in adults; prolonged in elderly (up to 6-8 hours) and hepatic impairment (up to 12 hours).
Ibuprofen: 2-4 hours (immediate-release). Diphenhydramine: 8-12 hours (prolonged in hepatic impairment).
Renal: ~50% as unchanged drug and metabolites (glucuronide conjugates); Biliary/fecal: ~40% as metabolites; <5% unchanged 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.
