It binds with high affinity to somatostatin receptor subtypes sst2 and sst5, potently inhibiting the pathological hypersecretion of growth hormone (GH), insulin-like growth factor-1 (IGF-1), serotonin, gastrin, VIP, and glucagon, and causing splanchnic vasoconstriction. Indicated for symptomatic control of carcinoid syndrome (flushing, severe diarrhea), VIPomas, acromegaly, emergency management of bleeding gastroesophageal varices, and prevention of postoperative pancreatic fistula.
