Somatostatin is a polypetide obtained synthetically or from the hypothalamus. It acts by inhibiting the release of growth hormone from the anterior pituitary. It also inhibits the release of thyrotrophin and corticotropin from the pituitary, glucagon and insulin from the pancreas. It also regulates duodenal and gastric secretions. It may also play a role in pain perception.
