Glucagon is NOT Glucose. It does however trigger the release of Glucose within the Body.
Glucagon helps maintain the level of glucose in the blood.
Glucose is stored in the liver in the form of glycogen, which is a starch-like polymer chain made up of glucose molecules. Liver cells (hepatocytes) have glucagon receptors. When glucagon binds to the glucagon receptors, the liver cells convert the glycogen polymer into individual glucose molecules, and release them into the bloodstream, in a process known as glycogenolysis. As these stores become depleted, glucagon then encourages the liver to synthesize additional glucose by gluconeogenesis.
Glucagon also regulates the rate of glucose production through lipolysis.
Injecting glucose raises blood sugar levels more rapidly, and more certainly, than the use of glucagon. Glucagon is contraindicated in a variety of medical conditions. In the prehospital setting there is often a lack of medical history. Another consideration was that we didn't want the paramedics having to mix anything and draw it into a syringe for use. D50w was much easier to store and use. Your information was very interesting though. Again, I apologize if I gave the impression glucose and glucagon were the same thing.
