Fifty-eight hyperprolactinemic women were followed up for 13 to 108 months after at least one bromocriptine-induced pregnancy for investigation of whether the pregnancy had any adverse long-term effects on the hyperprolactinemic state. Fifteen women had two term pregnancies. The prolactin (PRL) level decreased greater than 50% in 20 women after the pregnancy. Only two women showed a PRL level increase. Spontaneous uterine bleedings returned in 16 women, whereas 42 remained amenorrheic. Thus, bromocriptine-induced pregnancy in women with hyperprolactinemia has no negative long-term effect on PRL secretion.

Bromocriptine-induced coronary spasm caused acute coronary syndrome, which triggered its own clinical twin--Takotsubo syndrome.

Bromocriptine-induced coronary spasm (BICS) causing myocardial infarction has been reported. Association between BICS and Takotsubo syndrome (TS) has not been described. We report on a 37-year-old woman presenting with a clinical picture of acute coronary syndrome 1 day after initiation of treatment with bromocriptine for ablactation 3 weeks after a full-term spontaneous vaginal delivery.

High prolactin during pregnancy, which is essential for normal postpartum maternal behavior, increases neurogenesis in the subventricular zone of the lateral ventricle (SVZ) of the maternal brain. Because SVZ mitogenesis generates new olfactory neurons and may contribute to perception of novel odorants, we hypothesized that the prolactin-induced increase in SVZ mitogenesis during pregnancy might be important for normal maternal interactions with pups. To investigate this hypothesis, prolactin secretion was suppressed for 3 d early in pregnancy in mice, using a carefully timed dose of bromocriptine.

Objective: To explore the effect of total flavones from cuscuta chinensis (TFCC) on expression of Fas, PCNA and HB-EGF in SD rats model with bromocriptine-induced abortion.
Methods: The model rats of bromocriptine during 6-8 d of pregnancy induced early abortion was established, adopting respectively herbs in high and low dosage and progesterone affect model rat and after 12 d, Immunohistochemical was applied to determine Fas, HB-EGF and PCNA in deciduas and placenta.
Results: Expression of PCNA on trophoblast and deciduas, HB-EGF on trophoblast, PR on deciduas in the model used Semen cuscutae flavonoid, proesterone and normal pregnacy, were significantlly higher than those of the pure model.
Protective effects of baicalin against bromocriptine induced abortion in mice.

The Chinese herbal medicine Huang Qin (Radix Scutellariae) had been used for restless fetus for hundreds of years in China, however, little attention had been given to the components of the herb, specifically its ability to exert abortion-preventing effects at the maternal fatal interface. The present study was carried out to investigate the protective effects of baicalin and the possible mechanisms on pregnancies. Baicalin (at 10, 20, and 50 mg/kg BW respectively) was gavaged to bromocriptine-treated mice from gestation day (GD) 1 through GD 7.

Bromocriptine-induced tachycardia, persisting after adrenalectomy, is mediated by central dopamine D2 receptor stimulation through activation of the sympathetic outflow to the heart. The present study investigated the effects of malnutrition during pregnancy on bromocriptine-induced tachycardia in adult conscious rats. Malnourished rats were obtained by feeding dams a multideficient diet (providing 8% protein) during mating and pregnancy.
