溴隐亭可通过抑制催乳素（ＰＲＬ）治疗高ＰＲＬ血症。近年报道，此药物亦可治疗正常ＰＲＬ水平的排卵障碍。经ＬＨＲＨ 或ＴＲＨ 试验，溴隐亭治疗有效者均有潜在性高催乳素血症（ＯＨＰ）。在原因不明的不孕症患者中，约近一半系ＯＨＰ所致。ＯＨＰ是高催乳素血症的特殊类型，其ＰＲＬ分泌亢进的机制是因下丘脑部多巴胺活性下降，抑制ＰＲＬ分泌状态被解除，引起ＰＲＬ过度分泌。 Bromocriptine can treat high PRL hyperlipidemia by inhibiting prolactin (PRL). In recent years, this drug is also reported to treat ovulation disorders at normal PRL levels. By LHRH or TRH test, bromocriptine treatment are potentially high hyperprolactinemia (OHP). In unexplained infertility patients, about half caused by OHP. OHP is a special type of hyperprolactinemia. The mechanism of its hyperactivity of PRL is that the dopamine activity in the hypothalamus is reduced, and the secretion of PRL is relieved, resulting in the over-secretion of PRL.
