What is Prochlorperazine

A phenothiazine antipsychotic used principally in the treatment of nausea; vomiting; and vertigo. It is more likely than chlorpromazine to cause extrapyramidal disorders. (From Martindale, The Extra Pharmacopoeia, 30th ed, p612)

Prochlorperazine mechanism of action

The mechanism of action of prochlorperazine has not been fully determined, but may be primarily related to its antidopaminergic effects. Prochlorperazine blocks the D2 somatodendritic autoreceptor, resulting in the blockade of postsynaptic dopamine receptors in the mesolimbic system and an increased dopamine turnover. Prochlorperazine also has anti-emetic effects, which can be attributed to dopamine blockade in the chemoreceptor trigger zone. Prochlorperazine also blocks anticholinergic and alpha-adrenergic receptors, the blockade of alpha(1)-adrenergic receptors resulting in sedation, muscle relaxation, and hypotension.
