NAPROXEN vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2), thereby reducing the synthesis of prostaglandins involved in inflammation, pain, and fever.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
250-500 mg orally twice daily; maximum 1.5 g/day. For extended-release: 750-1000 mg orally once 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.

Clinical Note
moderateNaproxen + Gatifloxacin
"Naproxen may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateNaproxen + Rosoxacin
"Naproxen may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateNaproxen + Levofloxacin
"Naproxen may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateNaproxen + Trovafloxacin
"Naproxen may increase the neuroexcitatory activities of Trovafloxacin."
Terminal elimination half-life 12-17 hours (mean 14 hours); permits twice-daily dosing. Half-life prolonged in elderly and hepatic 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.
Primarily renal (95% as unchanged naproxen and 6-O-desmethylnaproxen); <5% fecal via biliary excretion.
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.
