Somatostatin acts as an inhibitor of various hormones such as cortisol, gastrin and secretin. The inhibition of these hormones leads to a decrease in movements in the stomach and intestines, a reduced secretion of digestive juices from the pancreas and an inhibition of the formation of gastric acid.

In addition, it is the antagonist of the growth hormone somatotropin. This is where the name of the hormone (synonym somatotropin-inhibitory hormone (SIH), inhibiting). Somatostatin also inhibits the other two pancreatic hormones, insulin and glucagon.

Synthetically produced somatostatin is used, among other things, to treat diseases such as acromegaly, in which there is an excess of the growth hormone somatotropin.
