Somatostatin (Native)

Somatostatin is a naturally occurring cyclic tetradecapeptide hormone produced by neuroendocrine cells throughout the body, including the hypothalamus, pancreas, and gastrointestinal tract. It functions as a potent inhibitor of growth hormone, insulin, glucagon, and various gastrointestinal hormones by binding to five subtypes of somatostatin receptors (SSTR1-5), which are G protein-coupled receptors.

The therapeutic rationale in oncology derives from the expression of somatostatin receptors on neuroendocrine tumors and the peptide's ability to inhibit tumor cell proliferation and hormone secretion. Native somatostatin has an extremely short plasma half-life of 2 to 3 minutes, limiting its clinical utility and necessitating the development of longer-acting synthetic analogues..

Somatostatin (Native) has received FDA approval and is available for clinical use under appropriate medical supervision. Consult a qualified healthcare provider for prescribing information.
