NAPROXEN SODIUM vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective cyclooxygenase (COX-1 and COX-2) inhibitor, reducing prostaglandin synthesis.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
220-550 mg orally twice daily; maximum 1375 mg/day.
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.

12–17 hours (terminal); allows twice-daily dosing; prolonged in elderly and renal impairment
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: 95% (as unchanged drug, conjugated naproxen, and 6-O-desmethyl naproxen); Fecal: <5%
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.
