CAMBIA vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, reducing prostaglandin synthesis and thereby alleviating inflammation, pain, and fever.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
50 mg orally once daily as needed for acute migraine, maximum 1 packet (50 mg) per 24 hours.
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 of diclofenac (active moiety) is approximately 1.9-2.1 hours. The clinical context: short half-life supports twice-daily dosing for acute pain.
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 50% of a dose is excreted in urine primarily as metabolites and conjugates, with less than 10% as unchanged drug. Biliary/fecal excretion accounts for about 40%.
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.
