CHILDREN'S ADVIL vs VIMOVO
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. This leads to decreased pain, inflammation, and fever through peripheral and central mechanisms.
VIMOVO (esomeprazole and naproxen) is a fixed-dose combination. Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2), decreasing prostaglandin synthesis, thereby reducing inflammation, pain, and fever. Esomeprazole is a proton pump inhibitor (PPI) that suppresses gastric acid secretion by inhibiting the H+/K+ ATPase in gastric parietal cells. The combination is intended to reduce the risk of NSAID-associated gastric ulcers.
Ibuprofen 200-400 mg orally every 4-6 hours as needed; maximum 1200 mg/day without prescription.
One tablet (naproxen 500 mg/esomeprazole 20 mg) orally twice daily.

Terminal elimination half-life is 1.9–2.3 hours in children. In neonates, half-life is prolonged (up to 6 hours). Clinical context: Requires dosing every 6–8 hours for sustained antipyresis.
Naproxen: 12-17 hours (prolonged in elderly and renal impairment; dosing interval typically 12 hours). Esomeprazole: 1-1.5 hours (metabolized by CYP2C19 and CYP3A4; no accumulation after repeated dosing).
Renal excretion of conjugated metabolites (glucuronide and sulfate) accounts for ~90% of the administered dose. Less than 5% is excreted unchanged in urine. Biliary/fecal elimination is minor (<5%).
Renal 50% as naproxen metabolites, <1% unchanged naproxen; less than 1% excreted unchanged in feces as esomeprazole; esomeprazole metabolites excreted in urine 80% and feces 20%.
