EFFECT OF METOCLOPRAMIDE ON SERUM PROLACTIN LEVELS IN HUMANS

Abstract

The effect of acute and chronic administration of metoclopramide on serum prolactin levels in normal subjects was studied. Metoclopramide 10 mg i.v. induced a prompt rise in serum prolactin levels in all subjects. At 180 min the levels remained high. Prolactin levels were markedly elevated during a 5 day course of treatment with metoclopramide in six subjects. It is suggested that metoclopramide could be used in the functional exploration of the hypothalamic-pituitary axis.
