Lanreotide acetate

What is Lanreotide acetate?

• Lanreotide acetate (Somatuline Depot) is a somatostatin analog used to treat gastroenteropancreatic neuroendocrine tumors that are advanced or have spread to other parts of the body.
• These tumors form in the stomach, small and large intestines, rectum, and pancreas.
• Lanreotide acetate is used for tumors that cannot be removed by surgery.
• It is also used to treat carcinoid syndrome and some patients with acromegaly (a condition in which the pituitary gland makes too much growth hormone) .

What are the uses of this medicine?

Lanreotide acetate (Somatuline Depot) is a prescription medicine used for: the long-term treatment of people with acromegaly when:

• surgery or radiotherapy have not worked well enough or
• they are not able to have surgery or radiotherapy

• the treatment of adults with a type of cancer known as neuroendocrine tumors, from the gastrointestinal tract or the pancreas (GEP-NETs) that has spread or cannot be removed by surgery
• the treatment of adults with carcinoid syndrome to reduce the need for the use of short-acting somatostatin medicine

How does this medicine work?

• Lanreotide (lan ree' oh tide) is a synthetic octapeptide and analogue of somatostatin that is used for its ability to suppress levels and activities of hormones (growth hormone, insulin, gastrin, secretin, glucagon) or active neuropeptides (serotonin, vasoactive intestinal polypeptide [VIP]).
• Natural somatostatin is produced in the hypothalamus and acts to suppress growth hormone release from the pituitary.
• Somatostatin is also found in other neurons throughout the body and particularly in intestinal and pancreatic neurons, where it is active in suppressing release of hormones and neuropeptides such as insulin, glucagon, gastrin, secretin, motilin, VIP, serotonin and cholecystokinin.
• Because of its short half-life (~3 minutes), somatostatin is impractical as a therapeutic agent, and analogues have been developed that have a more favorable pharmacological profile such as octreotide, pasireotide and lanreotide, all three of which have been marketed in long acting release (LRA) forms to allow once weekly or monthly administration.
• Lanreotide appears to interact largely with the somatostatin subtype 2 and possibly subtype 5 receptors, with little effect on subtypes 1, 3 and 4, but otherwise acts in a similar manner to somatostatin.
• Lanreotide therapy has been shown to improve symptoms and complications of several neuroendocrine tumors including abnormal growth in acromegaly due to growth hormone-secreting pituitary tumors, diarrhea due to VIP-secreting intestinal tumors, and flushing due to serotonin-producing carcinoid tumors.

How should this medicine be used?
