Medical therapy for Cushing's disease

Various drugs have been employed in the management of pituitary-dependent Cushing's disease. The neuromodulatory compounds used thus far have demonstrated true clinical efficacy only occasionally when employed as sole treatment. Steroid synthesis inhibitors are effective in the majority of cases in a dose-dependent manner. By their ability to correct hypercortisolism and its severe complications quickly, they are suitable for critical cases and in preparation for surgery. The clinical experience with the only glucocorticoid receptor antagonist that can be administered to humans is still too limited to assess its therapeutic validity. No medical strategy can be standardized for this complex condition. Different therapeutic tools should be selected according to the form of disease to be treated (hypothalamic/pituitary) and the peculiar clinical situation of each patient. Combined treatments may achieve better therapeutic efficacy.
