    Product Description

    Pimozide is a dopamine receptor antagonist (Kis = 2.4, 0.3, and 1.8 nM for D2, D3, and D4 receptors, respectively).1 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).2,3,4 Pimozide (0.5, 1, and 2 mg/kg) decreases the number of licks and reduces fluid intake of a sweetened solution in rats.5 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.6 Formulations containing pimozide have been used in the treatment of Tourette syndrome.
