What is cabergoline ?
The cabergoline is used to treat hyperprolactinemia ( high levels of prolactin, a natural substance that helps breast-feeding women produce milk but can cause symptoms such as infertility, sexual problems, and bone loss in women who are not breast-feeding or men ).
Cabergoline (brand names Dostinex and others), 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 its higher affinity for D2 receptor sites, less severe side effects, and more convenient dosing schedule than the older bromocriptine, though in pregnancy bromocriptine is often still chosen since there is less data on safety in pregnancy for cabergoline.
