Bromocriptine, methyl testosterone and placebo for inhibition of physiological lactation: a controlled study. 1978

J S Biggs, and N Hacker, and E Andrews, and C Munro

Lactation occurs when the fully developed breast is released from the inhibitory influence which oestrogen and progesterone exert upon the action of prolactin. The use of oestrogens to suppress lactation depends on a continuation of the peripheral, that is, mammary, inhibition of prolactin. Androgens are also believed to act by inhibition of the action of prolactin on the mammary gland epithelium. Bromocriptine, when compared in a double-blind trial with orally administered methyl testosterone and placebo, gave almost complete relief of breast discomfort and congestion, though a small amount of milk production was seen. Methyl testosterone, in the dosage used in this study, was quite ineffective in suppressing lactation or breast symptoms.

UI	MeSH Term	Description	Entries
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.

D010919	Placebos	Any dummy medication or treatment. Although placebos originally were medicinal preparations having no specific pharmacological activity against a targeted condition, the concept has been extended to include treatments or procedures, especially those administered to control groups in clinical trials in order to provide baseline measurements for the experimental protocol.	Sham Treatment
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.

D002986	Clinical Trials as Topic	Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries.	Clinical Trial as Topic

D004967	Estrogens	Compounds that interact with ESTROGEN RECEPTORS in target tissues to bring about the effects similar to those of ESTRADIOL. Estrogens stimulate the female reproductive organs, and the development of secondary female SEX CHARACTERISTICS.
