The primary outcome will be remission rate.', 'detailedDescription': 'Prolactinoma is the most common subtype of pituitary adenoma, and dopamine agonists are the gold standard for treatment, primarily CAB. The SPARAGMOS trial will be an interventional, randomized, open-label, multicenter study utilizing a high dose of CAB for \\~6 months to suppress prolactin levels, with the hypothetical goal of achieving greater tumor apoptosis and remission rates. The control group will receive CAB for two years at the lowest dose necessary to achieve normoprolactinemia, as per current guidelines.
