产品描述:
Pimozide is a dopamine receptor antagonist (Kis = 2.4, 0.3, and 1.8 nM for D2, D3, and D4 receptors, respectively).{25512} It also binds to eight additional receptors (Kds = 25-3,100 nM for the human receptors) and inhibits the voltage-gated sodium channel Nav1.2 and the voltage-gated potassium channel Kv11.1 (IC50s = 42 and 340 nM, respectively).{25511,26443,26441} Pimozide (0.5, 1, and 2 mg/kg) decreases the number of licks and reduces fluid intake of a sweetened solution in rats.{45613} It decreases the number of threats and attacks and increases immobility time in the neutral arena aggression test, indicating increased passiveness, in male mice when administered at a dose of 0.75 mg/kg for 10 days.{45614} Formulations containing pimozide have been used in the treatment of Tourette syndrome.
