Meloxicam-d3 is intended for use as an internal standard for the quantification of meloxicam by GC- or LC-MS. Meloxicam is a selective inhibitor of COX-2 (IC50s = 11.8 and 143 μM for COX-2 and COX-1, respectively, in an enzyme activity assay) and a non-steroidal anti-inflammatory drug (NSAID). Meloxicam (0.03%) reduces croton oil-induced increases in TNF-α and IL-1β mRNA levels and increases IL-10 mRNA levels in cornea in a rabbit model of acute ocular inflammation. It inhibits pleural plasma exudation in a carrageenan-induced rat model of pleurisy when administered at a dose of 3 mg/kg.In a canine model of unilateral osteoarthritis of the right stifle joint, meloxicam reduces prostaglandin E2 (PGE2) levels in plasma and right stifle joint synovial fluid when administered at a dose of 0.2 mg/kg. Formulations containing meloxicam have been used in the treatment of osteoarthritis and rheumatoid arthritis.
