Used primarily in the treatment of hyperprolactinemia, a condition characterized by excessive levels of prolactin hormone. It works by stimulating dopamine receptors in the brain, which helps reduce prolactin secretion from the pituitary gland. Commonly prescribed to manage symptoms like irregular menstrual cycles, infertility, and galactorrhea in both men and women. Also used in the management of Parkinson’s disease due to its dopamine agonist properties, helping to improve motor control by compensating for low dopamine levels. Its long half-life allows for less frequent dosing compared to other similar medications, improving patient compliance. In veterinary medicine, particularly in horses, it is used to treat conditions related to hormonal imbalances such as pseudopregnancy and delayed ovulation. Additionally, it has been explored off-label for conditions involving prolactin-dependent processes, though such uses require careful medical supervision.
