Octreotide (Sandostatin)

Peptide

Octreotide is a synthetic octapeptide analog of somatostatin with prolonged action. FDA-approved in 1988, it is available as immediate-release injection and long-acting repeatable (LAR) formulation. Primary indications include acromegaly, carcinoid syndrome, and neuroendocrine tumors. The PROMID trial demonstrated significant antiproliferative effects in midgut neuroendocrine tumors, and multiple trials confirm efficacy for GH/IGF-1 suppression in acromegaly.
