Â
How It Works
The rationale behind injections is their ability to replicate natural hormones' inhibitory actions on various bodily functions. Essentially, these injections work by attaching to receptors, thereby blocking the release of a range of hormones and neurotransmitters.
- Impact on Hormone Secretion: By regulating the secretion of growth hormone, insulin, glucagon, and other gastrointestinal hormones, somatostatin injections help alleviate symptoms associated with hormone-secreting tumors and related conditions.
- Effects on Tumor Growth and Blood Flow: In cases involving tumors and other cancers, somatostatin analogs can impede tumor growth by hindering the formation of new blood vessels. Additionally, these substances reduce blood flow in the region, which is crucial in managing gastrointestinal bleeding.
Â
Dosage and Administration
