🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Metamizole is a prodrug that is rapidly hydrolyzed to 4-methylaminoantipyrine (MAA), which is the active form. MAA inhibits both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2) enzymes, although its effects on COX-2 may be more pronounced. This inhibition reduces the synthesis of prostaglandins, which are key mediators of pain, inflammation, and fever. Additionally, metamizole may activate the endogenous opioid system and inhibit prostaglandin synthesis in the central nervous system, contributing to its analgesic effects. The antipyretic effect results from resetting the hypothalamic temperature set-point through reduced prostaglandin E2 production.
