A peptide that mimics endogenous somatostatin. Somatostatin is released by the pancreas, pyloric antrum, and duodenum and inhibits growth hormone, gastrin, Vasoactive intestinal peptide (VIP), gastrin, serotonin, and decreases Insulin like growth factor-1 (IGF-1) and decreases splanchnic blood flow.

Mechanism of Action

A peptide that mimics endogenous somatostatin. Somatostatin is released by the pancreas, pyloric antrum, and duodenum and inhibits Growth Gormone, Gastrin, Vasoactive intestinal peptide (VIP), Gastrin, Serotonin, and decreases Insulin like growth factor-1 (IGF-1), serotonin and it decreases splanchnic blood flow.

Comments

  • Although used in the ED mainly for sulfonylurea overdose and vatical bleeding, it is used in outpatient and inpatient medicine for the treatment of acromegaly, carcinoid tumors, and VIPomas
  • Octreotide was originally used as a opiod antagonist and is still used off label as a second/third line therapy for diarrhea from opiod withdrawal because of antidiarrheal properties.[1]
