Somatostatin Analog
Overview

A long-acting somatostatin analog FDA-approved for acromegaly and gastroenteropancreatic neuroendocrine tumors. Administered as a deep subcutaneous depot injection once monthly.

A synthetic octapeptide analog of somatostatin with a much longer half-life than the natural hormone. FDA-approved for acromegaly, carcinoid tumors, and VIPomas. One of the foundational peptide drugs in endocrinology.

Mechanism of Action

Binds primarily to somatostatin receptor subtypes 2 and 5 (SSTR2, SSTR5), inhibiting growth hormone secretion, reducing IGF-1 levels, and suppressing tumor growth in neuroendocrine tumors.

Binds to somatostatin receptors (primarily SSTR2 and SSTR5), inhibiting growth hormone, glucagon, and insulin secretion. Reduces splanchnic blood flow and inhibits GI motility and secretion.

Regulatory Status
FDA Approved

FDA-approved as Somatuline Depot (2007) for acromegaly and GEP-NETs. Administered as a deep subcutaneous injection in the gluteal region once every 4 weeks.

FDA Approved

FDA-approved as Sandostatin (1988, subcutaneous) and Sandostatin LAR (1998, monthly depot). Generic octreotide available. Widely used in endocrinology and oncology.
