What is the purpose of glucagon in drug form?

Glucagon in drug form serves the specific purpose of raising blood glucose levels in patients experiencing hypoglycemia, which is a condition characterized by dangerously low blood sugar levels. It functions by prompting the liver to release stored glucose into the bloodstream, effectively reversing the effects of low blood sugar. This action is particularly crucial in emergency situations where patients are unable to consume oral glucose due to confusion or loss of consciousness.

This mechanism makes glucagon an essential medication in emergency care, especially for individuals with diabetes or those who have ingested insulin or other glucose-lowering agents. Understanding the role of glucagon highlights its importance in providing critical intervention in hypoglycemic episodes, ensuring that patients can regain normal blood sugar levels quickly and safely.
