NORPROLAC is a pharmaceutical drug primarily used in the treatment of disorders related to high levels of the hormone prolactin, such as prolactinomas (prolactin-secreting tumors) and conditions causing hyperprolactinemia. The active ingredient in NORPROLAC is quinagolide, which functions as a dopamine agonist. By mimicking the action of dopamine on its receptors in the brain, quinagolide inhibits the secretion of prolactin from the pituitary gland. This reduction in prolactin levels can alleviate symptoms associated with elevated prolactin, such as infertility, sexual dysfunction, and irregular menstrual cycles in women, and impotence in men. NORPROLAC is administered orally and is available in tablet form. As with any medication, it is important to use NORPROLAC under the guidance of a healthcare professional to ensure its safe and effective use.
