Cabergoline

Cabergoline (name brands Dostinex and Cabaser) is a dopamine receptor agonist and uncategorized drug which supresses the production of prolactin in pituitary gland. It is an ergot-derivative.

It is used to prevent the production of excess prolactin in the case of certain pituitary tumors, and in some countries (but not the United States) has been approved as a therapy for Parkinson's Disease. The normal dosage for prolactinoma is 0.5 mg twice weekly; dosages for treating Parkinson's are higher.

It has at times been used as an adjunct to SSRI antidepressants as there is some evidence that it counteracts certain side effects of those drugs such as reduced libido and anorgasmia. It also has been suggested online that it has a possible recreational use in reducing or eliminating the male refractory period.
