Abstract

Meloxicam is a new preferential cyclooxygenase-2 (COX-2) inhibitor currently for the treatment of osteoarthritis and rheumatoid arthritis. Its pharmacokinetic profile is characterized by a prolonged and almost complete absorption and the drug is > 99.5% bound to plasma proteins. Meloxicam is metabolized to four biologically inactive main metabolites, which are excreted in both urine and faeces. The elimination half-life (t1/2) of meloxicam is approximately 20 h. This is reflected in a total plasma clearance (CL) of 0.42-0.48 1/h. Steady-state plasma concentrations are achieved within 3-5 days. The pharmacokinetic parameters of meloxicam are linear over the dose range 7.5-30 mg and bioequivalence has been shown for a number of different formulations. No interactions were observed following the concomitant administration of food, cimetidine, antacid, aspirin, beta-acetyldigoxin, methotrexate, warfarin or furosemide. Neither hepatic insufficiency nor moderate renal dysfunction have any relevant effects on the pharmacokinetics of meloxicam and dosage adjustments in the elderly are not required.
