meloxicam
Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) with analgesic and fever reducer effects. It is a derivative of oxicam, closely related to piroxicam, and falls in the enolic acid group of NSAIDs. It was developed by Boehringer-Ingelheim. Meloxicam starts to relieve pain about 30–60 minutes after administration.
==Mechanism of action==
(詳細はcyclooxygenase (COX), the enzyme responsible for converting arachidonic acid into prostaglandin H2—the first step in the synthesis of prostaglandins, which are mediators of inflammation.
Meloxicam has been shown, especially at its low therapeutic doses, selectively to inhibit COX-2 over COX-1.〔
Meloxicam concentrations in synovial fluid range from 40% to 50% of those in plasma. The free fraction in synovial fluid is 2.5 times higher than in plasma, due to the lower albumin content in synovial fluid as compared to plasma. The significance of this penetration is unknown,〔 but it may account for the fact that it performs exceptionally well in treatment of arthritis in animal models.
