MEASURIN vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Measurin is an aspirin preparation that irreversibly inhibits cyclooxygenase (COX-1 and COX-2), thereby reducing prostaglandin and thromboxane synthesis. This results in analgesic, antipyretic, anti-inflammatory, and antiplatelet effects.
COX-2 inhibitor; reduces prostaglandin synthesis via inhibition of cyclooxygenase-2 (COX-2) with minimal COX-1 inhibition.
325-650 mg orally every 4-6 hours as needed; maximum 4 g/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.

Plasma elimination half-life is 2-3 hours at low doses (antiplatelet) and increases to 15-30 hours at anti-inflammatory doses due to saturation of hepatic metabolism; clinical context: higher doses require longer dosing intervals to avoid accumulation.
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 excretion of salicylate and its metabolites (salicyluric acid, salicyl phenolic glucuronide, salicyl acyl glucuronide, gentisic acid) accounts for >90% of elimination; minor biliary/fecal excretion (<5%) occurs.
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.
