Inhibition of prolactin and lactation by methylergometrine hydrogenmaleate. 1979

F Peters, and M Lummerich, and M Breckwoldt

Reports on the effect of methylergometrine hydrogenmaleate (MEM) on prolactin (PRL) secretion and lactation are still controversial. Therefore a prospective study was designed to follow the influence of MEM on post-partum PRL levels and milk production. MEM was given orally to 30 post-partum women from day 1 to day 7 in a daily dose of 0.6 mg. Thirty untreated women served as control. PRL plasma levels and milk yield were compared at day 1, 3 and 7. PRL levels were significantly lower in the treated group at day 7 (P less than 0.01), while the difference at day 3 was statistically not significant. Milk yield was significantly reduced at day 3 (P less than 0.05) and day 7 (P less than 0.01). These results indicate PRL inhibiting properties of MEM resulting consequently in reduced lactation.

D007774 Lactation The processes of milk secretion by the maternal MAMMARY GLANDS after PARTURITION. The proliferation of the mammary glandular tissue, milk synthesis, and milk expulsion or let down are regulated by the interactions of several hormones including ESTRADIOL; PROGESTERONE; PROLACTIN; and OXYTOCIN.

D011247 Pregnancy The status during which female mammals carry their developing young (EMBRYOS or FETUSES) in utero before birth, beginning from FERTILIZATION to BIRTH. Gestation,Pregnancies
D011388 Prolactin A lactogenic hormone secreted by the adenohypophysis (PITUITARY GLAND, ANTERIOR). It is a polypeptide of approximately 23 kD. Besides its major action on lactation, in some species prolactin exerts effects on reproduction, maternal behavior, fat metabolism, immunomodulation and osmoregulation. Prolactin receptors are present in the mammary gland, hypothalamus, liver, ovary, testis, and prostate.
