Cabergoline (that is most famous sold under trade name Cabaser and Dostinex – but there are many others), which is an ergot derivative, is a potent dopamine receptor agonist on D2 receptors. There are studies proving that Cabergoline is directly inhibiting pituitary lactotroph (prolactin) cells. Very often, this product is used in the management of prolactinomas because of its higher affinity for the D2 receptor sites and less severe side effects. This product is known to have only one route of administration – oral, which means that all the products containing Cabergoline should be in form of tablet. The product got popular in the world of bodybuilding because of its ability to offer an “adrenaline rush” and ignoring pains while pushing muscles. But it is mainly used as a prolactin inhibitor.
