A typical antipsychotic; selectively binds to dopamine D2 over D1, D3, and D4 receptors (Kis = 0.417, 338, 186.2, and 363.1 nM, respectively); binds to various 5-HT, histamine H1, α1- and α2-adrenergic, muscarinic acetylcholine, and sigma receptors (Kis = 15-5,754 nM) as well as the dopamine, norepinephrine, and serotonin transporters (Kis = 3.16-30 μM); reduces spontaneous and amphetamine-induced locomotor activity in rats; enhances latent inhibition in rats; increases competitive behavior in submissive mice
