Pituitary tumors can cause symptoms of mass effect and hormonal hypersecretion that can be reversed with surgical resection or debulking of the adenoma, radiotherapy, or medical treatment. Medical treatment is the primary choice for prolactinomas because dopamine agonists are very effective in the treatment of these tumors, with rates of control (tumor size reduction and hormone suppression) as high as 80-90%, for microprolactinomas and 60-75% for macroprolactinomas. The function of dopamine receptors in other histotypes of pituitary adenoma is still debated. However, new insights into receptor physiology and the introduction of new clinically available, as well as experimental, compounds have reopened a potential role of dopaminergic drugs in the medical treatment of pituitary tumors. The differences between the effectiveness and the resistance to different dopaminergic agents, the new challenging results from clinical and experimental studies, as well as the future of dopamine agonists in the therapy of pituitary tumors are discussed.
