Octreotide acetate is a synthetic analog of the natural hormone somatostatin, primarily used in the treatment of acromegaly, carcinoid tumors, and vasoactive intestinal peptide-secreting tumors. It works by inhibiting the release of certain hormones and neurotransmitters, thereby helping to reduce symptoms associated with these conditions. Octreotide acetate is available in injectable and long-acting release formulations, providing flexibility in the management of various disorders.
