| Name: |
OCTREOTIDE (SandostatinR) |
| Classification: |
synthetic octapeptide analogue of naturally occurring somatostatin
- inhibits pathologically increased secretion of peptides and serotonin produced within the gastroentero-pancreatic (GEP) endocrine system and growth hormone, thus used in pancreatitis or post pancreatic surgery to prevent complications such as pancreatic fistula or abscess
- thought to reduce splanchnic blood flow primarily by inhibiting vasoactive gastrointestinal hormone secretion and exerting a direct vasomotor effect on splanchnic vessels, thus reducing portal blood flow; used in the emergency management of bleeding gastroesophageal varices in patients with cirrhosis
