Cabergoline
（重定向自Dostinex）
Cabergoline (brand names Caberlin, Dostinex and Cabaser), an ergot derivative, is a potent dopamine receptor agonist on D2 receptors. Rat studies show cabergoline has a direct inhibitory effect on pituitary lactotroph (prolactin) cells. It is frequently used as a first-line agent in the management of prolactinomas due to higher affinity for D2 receptor sites, less severe side effects, and more convenient dosing schedule than the older bromocriptine.
