CHILDREN'S ADVIL-FLAVORED vs DICLOFENAC
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, resulting in antipyretic, analgesic, and anti-inflammatory effects.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription, up to 3200 mg/day under medical supervision.
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 (up to 30 hours) and hepatic impairment.
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 conjugated metabolites (75-80% as glucuronide and sulfate conjugates, <10% as unchanged drug); biliary/fecal elimination accounts for <5%.
Renal (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
