Octreotide, sold under the brand name Sandostatin among others, is an octapeptide that mimics natural somatostatin pharmacologically, though it is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone. It was first synthesized in 1979 and binds predominantly to the somatostatin receptors SSTR2 and SSTR5. [5]
Zinc and vitamin D are also essential for bone health but have the added benefit for men over 50 by reducing the risk of erectile dysfunction, a condition commonly affecting men over age 40 ...
Somatostatin receptor antagonists (or somatostatin inhibitors) are a class of chemical compounds that work by imitating the structure of the neuropeptide somatostatin. The somatostatin receptors are G protein-coupled receptors. Somatostatin receptor subtypes in humans are sstr1, 2A, 2 B, 3, 4 and 5. [1]
It is a non-selective somatostatin receptor antagonist, [37] inhibiting the effects of somatostatin on target cells in the gastrointestinal tract, pancreas, hypothalamus, and central nervous system. [2] Cyclosomatostatin is used as a research chemical to investigate the effects of somatostatin on different cell types by antagonizing its ...
Octreotide (brand name Sandostatin, Novartis Pharmaceuticals) is an octapeptide that mimics natural somatostatin pharmacologically, though is a more potent inhibitor of growth hormone, glucagon, and insulin than the natural hormone, and has a much longer half-life (about 90 minutes, compared to 2–3 minutes for somatostatin). Since it is ...
The primary current medical treatment of acromegaly is to use somatostatin analogues – octreotide (Sandostatin) or lanreotide (Somatuline). These somatostatin analogues are synthetic forms of a brain hormone, somatostatin, which stops GH production. The long-acting forms of these drugs must be injected every 2 to 4 weeks for effective treatment.
An octreotide scan is a type of SPECT scintigraphy used to find carcinoid, pancreatic neuroendocrine tumors, and to localize sarcoidosis. It is also called somatostatin receptor scintigraphy (SRS). Octreotide , a drug similar to somatostatin , is radiolabeled with indium-111 , [ 1 ] and is injected into a vein and travels through the bloodstream.
Research in men and women with Addison’s disease showed that 50 milligrams of DHEA a day for three months led to improved hormone levels, well-being, self-esteem, fatigue and mood. PeopleImages ...
