Metamizole has a fast analgesic effect but a short half-life and duration of action. The exact mechanism of action of metamizole is currently not fully known. Studies showed that metamizole appears to be a moderate to strong inductor of the enzymes CYP3A4, CYP2B6 and CYP2C19; a weak inductor of CYP2C9; and a moderate inhibitor of CYP1A2. Furthermore, metamizole inhibits the effect of acetylsalicylic acid when taken simultaneously. Metamizole should be cautiously used together with other drugs that can cause agranulocytosis.
