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, 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 and thereby decreasing inflammation, pain, and fever.
200-400 mg orally every 6-8 hours as needed; maximum 1200 mg/day. Extended-release: 400-1000 mg orally once daily.
IV: 10 mg/kg over 15 minutes, followed by 5 mg/kg at 24, 48, and 72 hours after the first dose.

Terminal elimination half-life is approximately 6.5-7.5 hours (range 5-8 hours). With multiple dosing, the half-life remains unchanged, indicating linear kinetics. No accumulation in normal renal function.

Terminal elimination half-life is approximately 2.5 to 4 hours in adults. In preterm neonates (target population for Neoprofen), half-life is prolonged due to immature renal function: mean 30.5 hours (range 20–50 hours) after first dose, decreasing to ~15 hours after third dose. Clinical relevance: requires careful dosing intervals in neonates to avoid accumulation.
Renal excretion (72% as metabolites, including glucuronides and hydroxylated derivatives, less than 1% unchanged); fecal excretion (16%, primarily as metabolites); biliary excretion contributes to enterohepatic recirculation.
Ibuprofen is primarily excreted renally as metabolites (approximately 90% of the dose), with less than 1% excreted unchanged. A small fraction (≤10%) is eliminated via bile/feces. For Neoprofen (ibuprofen lysine specifically used for patent ductus arteriosus), renal excretion accounts for >90% of elimination, predominantly as glucuronide conjugates and hydroxylated metabolites.
