Topic: Octreotide


In the News (Tue 29 Dec 09)

  
  Octreotide - Wikipedia, the free encyclopedia
Octreotide (brand name Sandostatin, Novartis Pharmaceuticals) is an octopeptide that mimics natural somatostatin pharmacologically, though is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone.
The Food and Drug Administration (FDA) has approved the usage of a salt form of this peptide, octreotide acetate, as an injectable depot formulation for the treatment of acromegaly, the treatment of diarrhea and flushing episodes associated with carcinoid syndrome, and treatment of diarrhea in patients with vasoactive intestinal peptide-secreting tumors (VIPomas).
Octreotide has also been used off-label for the treatment of severe, refractory diarrhea from other causes.

 Octreotide (somatostatin analogue)
Octreotide was FDA-approved in October 1988 for the treatment of carcinoid tumors and VIPomas.
Octreotide's effects were seen in patients with progressive autonomic failure, multiple-organ-system atrophy, and diabetic autonomic neuropathy but not in patients with sympathotonic orthostatic hypotension.
Further investigation is needed to determine octreotide's role as an alternative for patients with thyrotropinomas that are refractory to surgery and radiation.

Octreotide is the acetate salt of a cyclic octapeptide.
Depot (octreotide acetate for injectable suspension) is available in a vial containing the sterile drug product, which when mixed with diluent, becomes a suspension that is given as a monthly intragluteal injection.
The octreotide is uniformly distributed within the microspheres which are made of a biodegradable glucose star polymer, D,L-lactic and glycolic acids copolymer.

 Acromegaly & Octreotide - Neuroendocrine Clinical Center & Pituitary Tumor Center at MGH/Harvard
Octreotide, a somatostatin analogue administered subcutaneously, is chemically modified to result in a prolonged half life, less insulin suppression and no post-infusion rebound.
Octreotide may be administered continuously by a subcutaneous pump to patients with refractory acromegaly to prevent escape of GH between injections.
A PET scan is used to localize binding of the radiolabeled octreotide to the pituitary adenoma, and binding of the radiolabeled octreotide suggests the presence of octreotide receptors.

 Indium
While researchers are now using the In-111 Octreotide as a new treatment for TED and apparently finding some success, I am still thinking that it may be the Indium, the biotin, or the combination of the two nutrients that are really the reason for the success of the treatment.
The role of octreotide in the treatment of carcinoid tumour and the usefulness of In-111-pentetreotide (octreoscan) in the localization and prediction of the response to treatment with octreotide is discussed.
The aims of the present study were to confirm the beneficial effect of octreotide in patients with TED, to investigate the presence of somatostatin receptors in the orbital area and also, if possible, to ascertain whether this technique could select those patients with TED who might benefit from treatment with octreotide.
