Abstract
The effect of acute and chronic maternal administration of metoclopramide on prolactin levels in serum of umbilical vein and artery was investigated in 30 women with normal term pregnancy during labor [to study its possible therapeutic effect on fetal lung maturation]. Serum maternal prolactin increased significantly when 20 mg metoclopramide was given i.v. 30-45 min before vaginal delivery. Prolactin values in serum of umbilical vessels did not change as compared with control values when metoclopramide was given to the mother either as a 20-mg i.v. bolus injection or per os for the last 4 days of pregnancy until delivery. Oral administration of metoclopramide in late pregnancy evoked a significant increase in maternal serum prolactin levels. It is suggested that, in humans, therapeutic doses of metoclopramide administered to the mother in late pregnancy stimulate maternal, but not fetal, prolactin secretion.
