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, thereby reducing the synthesis of prostaglandins involved in pain, inflammation, and fever.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
400 mg (two 200 mg Liqui-Gels) orally every 6 to 8 hours as needed; maximum 1200 mg per day.
Oral: 50 mg twice daily or 75 mg twice daily; maximum 150 mg/day. Topical: apply 4 times daily. IM: 75 mg once daily.

Terminal elimination half-life is approximately 2 hours (range 1.8–3.5 hours). In clinical context, this short half-life supports dosing every 4–6 hours for acute migraine treatment, but drug effects may persist beyond this due to slow dissociation from COX enzymes.
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 excretion of unchanged drug and metabolites accounts for approximately 90% of an administered dose, with about 10% excreted in feces via bile. Less than 1% is excreted unchanged in urine; the remainder as conjugates and oxidative metabolites.
Renal (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
