Mirepax is a medication primarily used to treat conditions associated with excessive or inappropriate secretion of certain hormones, particularly in the context of pituitary disorders. It contains the active ingredient cabergoline, which is a dopamine agonist that works by stimulating dopamine receptors in the brain. This action can help regulate hormonal levels and manage symptoms related to conditions like hyperprolactinemia. Mirepax is typically prescribed by healthcare professionals and should be taken as directed.
