Lactogenic pituitary tumor is medically called pituitary lactinoma. The treatment of pituitary prolactinoma mainly includes medication, surgery and radiation therapy. i. The main medications used in medication are dopamine receptor agonists, of which the representative drugs are bromocriptine, cartegolide, and quinagolide and pergolide. Bromocriptine is the most commonly used internal medicine, which is a derivative of ergot, a specific dopamine receptor agonist that can inhibit the secretion of lactogen and has a certain effect on the volume reduction of prolactinoma. Second, surgical treatment, for macroadenomas that are not sensitive to medication or patients cannot adhere to medication, surgical treatment can be an option. Third, radiation therapy, which is applicable when the lactin level does not drop to normal level after surgery and there is a suspicion of residual tumor tissue, can be chosen.
