NAPRELAN vs VIMOVO
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 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.
750 mg to 1000 mg orally once daily, with or without food.
One tablet (naproxen 500 mg/esomeprazole 20 mg) orally twice daily.

Terminal elimination half-life: 10-20 hours; context: allows twice-daily or once-daily dosing for chronic pain or inflammation.
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: 50-60% as metabolites and conjugates; biliary/fecal: ~5%; remainder uncharacterized.
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%.
