DICLOFENAC vs VIVLODEX
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Diclofenac inhibits cyclooxygenase (COX) enzymes, primarily COX-2, 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.
Oral: 50 mg twice daily or 75 mg twice daily; maximum 150 mg/day. Topical: apply 4 times daily. IM: 75 mg 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 ~2 h (diclofenac immediate-release); enterohepatic recirculation may produce secondary peaks. Clinical context: Short half-life requires multiple daily dosing for sustained effect.
Clinical Note
moderateDiclofenac + Gatifloxacin
"Diclofenac may increase the neuroexcitatory activities of Gatifloxacin."
Clinical Note
moderateDiclofenac + Rosoxacin
"Diclofenac may increase the neuroexcitatory activities of Rosoxacin."
Clinical Note
moderateDiclofenac + Levofloxacin
"Diclofenac may increase the neuroexcitatory activities of Levofloxacin."
Clinical Note
moderateDiclofenac + Trovafloxacin
"Diclofenac may increase the neuroexcitatory activities of Trovafloxacin."
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 (65% as metabolites, <1% unchanged); biliary/fecal (35% as metabolites).
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.
