DIFLUNISAL vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, reducing prostaglandin synthesis, thereby exerting analgesic, anti-inflammatory, and antipyretic effects.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
500 mg to 1000 mg orally initially, then 250 mg to 500 mg every 8 to 12 hours. Maximum daily dose: 1500 mg.
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.

8-12 hours (prolonged in renal impairment; clinical context: permits twice-daily 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 (90% as glucuronide conjugates, <5% unchanged); biliary/fecal (<10%)
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.
