CHILDREN'S MOTRIN vs DICLOFENAC
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), reducing prostaglandin synthesis, thereby decreasing pain, fever, and inflammation.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day without prescription, extended release forms: 600-800 mg orally twice daily.
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 in children; prolonged in neonates and hepatic impairment.
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 (90%) as inactive metabolites and conjugates; fecal (<5%).
Renal (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
