What is Cabergoline?
Cabergoline is a long-acting selective dopamine D2 receptor agonist (~65hr half-life) that suppresses prolactin secretion from anterior pituitary lactotrophs. Research: hyperprolactinaemia, prolactinoma biology, D2 receptor pharmacology, and prolactin-mediated LH/FSH suppression on the HPG axis. CAS 81409-90-7.
