VIMOVO vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
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.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
One tablet (naproxen 500 mg/esomeprazole 20 mg) orally twice daily.
Once daily oral administration of 100 mg or 200 mg capsules. The recommended dose is 100 mg once daily; dose may be increased to 200 mg once daily if response is inadequate. Maximum daily dose: 200 mg.

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).
Terminal elimination half-life of the active moiety meloxicam is approximately 20 hours (range 12-24 h), allowing once-daily dosing in chronic pain.
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%.
VIVLODEX is a meloxicam NSAID prodrug. Following hydrolysis to meloxicam, excretion is primarily hepatic (metabolism) and renal (urine). Approximately 50% of meloxicam dose is excreted in urine as metabolites and <5% as parent drug; about 40% in feces. Biliary excretion is minor.
