Pizotifen Malate CAS 5189-11-7

This product is a tricyclic serotonin receptor antagonist API manufactured by chemical synthesis, constructing the dibenzocycloheptene core through multi-step cyclization and functionalization. The process is mature with controllable impurities and favorable stability. It combines potent 5-HT₂ receptor antagonism with mild histamine H₁ receptor blockade, effectively reducing the frequency and intensity of migraine attacks. It is mainly used in tablet production for migraine prophylaxis and vascular headache treatments.
