Somatostatin and semaglutide are two different drugs used for distinct therapeutic purposes.

Mechanism of Action

Somatostatin is a peptide hormone that functions by inhibiting and regulating the release of various endocrine substances. It primarily lowers blood glucose levels by binding to specific receptors and inhibiting the release of insulin and glucose-dependent insulin.

Semaglutide is a blood glucose-regulating drug belonging to the class of GLP-1 receptor agonists. It lowers blood glucose levels by mimicking the action of glucagon-like peptide-1 (GLP-1). GLP-1 is an insulin-stimulating hormone that increases insulin secretion, inhibits glucagon secretion, and delays gastric emptying, thereby reducing appetite and lowering blood glucose concentrations.
