Pimozide is a member of the class of benzimidazoles that is 1,3-dihydro-2H-benzimidazol-2-one in which one of the nitrogens is substituted by a piperidin-4-yl group, which in turn is substituted on the nitrogen by a 4,4-bis(p-fluorophenyl)butyl group. It has a role as a H1-receptor antagonist, a serotonergic antagonist, a first generation antipsychotic, an antidyskinesia agent and a dopaminergic antagonist. It is a member of benzimidazoles, an organofluorine compound and a heteroarylpiperidine.Pimozide is an orally active antipsychotic drug product which shares with other antipsychotics the ability to blockade dopaminergic receptors on neurons in the central nervous system. The ability of pimozide to suppress motor and phonic tics in Tourette's Disorder is thought to be primarily a function of its dopaminergic blocking activity. Pimozide binds and inhibits the dopamine D2 receptor in the CNS.
