ADVIL MIGRAINE LIQUI-GELS 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, thereby reducing the synthesis of prostaglandins involved in pain, inflammation, and fever.
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.
400 mg (two 200 mg Liqui-Gels) orally every 6 to 8 hours as needed; maximum 1200 mg per day.
One tablet (naproxen 500 mg/esomeprazole 20 mg) orally twice 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.
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 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 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%.
