Purpose of review To discuss the role of medical therapy of acromegaly as a first-line treatment, focusing on recent data on the use of somatostatin analogs (SSAs), the first-choice pharmacotherapy for treating acromegaly. Recent findings Despite pituitary surgery and radiotherapy, a significant number of patients with acromegaly needed adjuvant medical therapy, and primary medical therapy nowadays is increasingly considered. According to a recent consensus statement on the management of acromegaly, primary pharmacological therapy with SSAs may be indicated in patients who are otherwise poor surgical candidates or refuse surgery, and in those in whom there is a low probability of a surgical cure. The long-acting SSAs have been found to be effective in improving symptoms and signs of acromegaly in a high percentage of patients and induce normalization of growth hormone and insulin-like growth factor-I levels approximately in 60-80% of patients, respectively. Evidence has suggested that SSAs induce a clinically significant tumor shrinkage when given as first-line, when this reduction of tumor volume could be helpful in improving the outcome of subsequent surgery or improving the clinical syndrome in patients with unacceptable surgical risk, whereas the tumor shrinkage was seen less frequently when the drug was used after surgical resection and/or radiotherapy. Summary Pharmacological management plays a pivotal role in the treatment of acromegaly, and first-line medical therapy with SSAs is being widely used in clinical practice, either prior to surgery or in patients who are otherwise poor surgical candidates and in those in whom there is a low probability of a surgical cure.
