同義語： Mobic, Metacam, Movalis, UH-AC 62, 4-Hydroxy-2-methyl-N-(5-methyl-2-thiazolyl)-2H-1,2-benzothiazine-3-carboxamide 1,1-dioxide, Meloxicamum

Meloxicam is an oxicam-class nonsteroidal anti-inflammatory drug (NSAID) that acts as a preferential cyclooxygenase-2 (COX-2) inhibitor. Its chemical structure features a 1,2-benzothiazine-3-carboxamide 1,1-dioxide core, with a 4-hydroxy group and a 2-methyl substituent that enable chelation with the active site of COX-2. This structural motif yields a higher affinity for COX-2 over COX-1, reducing gastrointestinal irritation compared to non-selective NSAIDs. The drug is widely used for its analgesic, anti-inflammatory, and antipyretic properties in both human and veterinary medicine.

Meloxicam is available in various dosage forms, including oral tablets, suspensions, and injectable solutions. It is indicated for the relief of signs and symptoms of osteoarthritis and rheumatoid arthritis in humans, and for the control of pain and inflammation in animals, particularly dogs and cats. The compound is practically insoluble in water but soluble in organic solvents such as dimethylformamide. Its therapeutic efficacy and safety profile have made it a staple in pain management protocols worldwide.

化学構造と性質

Meloxicam belongs to the oxicam family, characterized by a 1,2-benzothiazine ring system. The presence of the 4-hydroxy group allows for keto-enol tautomerism, which is crucial for its binding to the COX-2 enzyme. The enolic form chelates with the active site iron, while the 2-methyl group enhances lipophilicity, facilitating membrane penetration. Meloxicam is a weak acid with a pKa of approximately 4.2, and its solubility is pH-dependent. It is stable under normal storage conditions but should be protected from light and moisture.

作用機序

• COX-2 inhibition: Meloxicam preferentially inhibits COX-2, reducing the production of prostaglandins that mediate pain and inflammation, while sparing COX-1 to some extent, which helps maintain gastric mucosal integrity.
• Anti-inflammatory effects: By blocking COX-2, meloxicam decreases prostaglandin synthesis at sites of inflammation, alleviating swelling, pain, and fever.
• Analgesic activity: Reduced prostaglandin levels in the central nervous system contribute to its analgesic effects.
• Antipyretic action: Inhibition of COX-2 in the hypothalamus lowers fever by decreasing prostaglandin E2 production.
