Prochlorperazine (Compazine, Stemzine, Buccastem, Stemetil, Phenotil) is a dopamine (D2) receptor antagonist that belongs to the phenothiazine class of antipsychotic agents that are used for the treatment of nausea and vertigo. It is also a highly potent typical antipsychotic, 10–20× more potent than chlorpromazine. It is also used to treat migraine headaches.[1]

Pharmacology

Prochlorperazine is thought to exert its antipsychotic effects by blocking dopamine receptors.[7]

Prochlorperazine is analogous to chlorpromazine, both of these agents antagonize dopaminergic D2 receptors in various pathways of the central nervous system. This D2 blockade results in antipsychotic, antiemetic and other effects. Hyperprolactinaemia is a side effect of dopamine antagonists as blockade of D2 receptors within the tuberoinfundibular pathway results in increased plasma levels of prolactin.

Subjective effects

The effects listed below are based upon the subjective effects index and personal experiences of PsychonautWiki contributors. The listed effects will rarely if ever occur all at once but heavier dosages will increase the chances and are more likely to induce a full range of effects.

Physical effects
