Potent dopaminergic D~2~ antagonist. Has weak α~1~-adrenolitic activity. It is a moderate serotonin 5-HT~2~ antagonist. Has no antihistaminic or anticholinergic effects. Its effect on delirium and hallucinations is due to its antidopaminergic action. This is probably due to its action on the mesocortex, limbic system, and basal ganglia (nigrostriate pathway). This last may justify its extrapyramidal effects. Its antidopaminergic action also explains its effects on nausea and vomiting, on gastrointestinal sphincters and the increase in prolactin liberation.
