Secretion of prolactin is inhibited by:: (A) Dopamine, (B) Nor-adrenaline, (C) Adrenaline, (D) Serotonin
Answer is A. Dopamine keeps inhibitory control over prolactin.This explains the reason behind hyperprolactinemia in psychotic patients who are treated with dopamine antagonists.Dopamine agonists (bromocriptine, cabergoline) therefore are used in treatment of hyperprolactinemia, acromegaly.
