Octreotide, sold under the brand name Sandostatin among others, is an octapeptide that mimics natural somatostatin pharmacologically, though it is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone. It was first synthesized in 1979 and binds predominantly to the somatostatin receptors SSTR2 and SSTR5.[5]

It was approved for use in the United States in 1988.[2][1] Octreotide was approved for medical use in the European Union in 2022.[4] As of June 2020, octreotide is the first oral somatostatin analog (SSA) approved by the FDA.[6] It is on the World Health Organization's List of Essential Medicines.[7]
