Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Non-selective COX-1 and COX-2 inhibitor, reducing prostaglandin synthesis via inhibition of cyclooxygenase, leading to anti-inflammatory, analgesic, and antipyretic effects.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
Oral: 50 mg two to three times daily; maximum 150 mg/day. Topical: 1% gel applied four times daily. Rectal: 100 mg suppository 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.

Terminal elimination half-life approximately 2 hours (range 1.3–3.1 h). Short half-life requires frequent dosing; no accumulation with normal dosing intervals.
Terminal elimination half-life of the active moiety meloxicam is approximately 20 hours (range 12-24 h), allowing once-daily dosing in chronic pain.
Approximately 65% renal as glucuronide conjugates and inactive metabolites, ~20% biliary/fecal. Less than 1% unchanged in urine.
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.
