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 synthesis of prostaglandins involved in inflammation, pain, and fever.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
800 mg IV every 8 hours as a 30-minute infusion; alternatively, 400 mg IV every 6 hours. Maximum daily dose: 2400 mg.
Oral: 50 mg twice daily or 75 mg twice daily; maximum 150 mg/day. Topical: apply 4 times daily. IM: 75 mg once daily.

2-4 hours (terminal half-life). Clinical context: Requires dosing every 6-8 hours for sustained effect; no accumulation with normal hepatic function.
Clinical Note
moderateDiclofenac + Gatifloxacin
"Diclofenac may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateDiclofenac + Rosoxacin
"Diclofenac may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateDiclofenac + Levofloxacin
"Diclofenac may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateDiclofenac + Trovafloxacin
"Diclofenac may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life ~2 h (diclofenac immediate-release); enterohepatic recirculation may produce secondary peaks. Clinical context: Short half-life requires multiple daily dosing for sustained effect.
Renal (primarily as glucuronide conjugates and inactive metabolites; <10% unchanged). Biliary/fecal elimination is negligible.
Renal (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
