Glucagon is a hormone that is naturally secreted by the alpha cells of the pancreas to balance glucose level and maintain blood sugar levels in the absence of food. This hormone gets activated in the body long after the food is digested or in between two meals. .An absence of glucagon leads to hyperinsulinaemia or high insulin levels in the blood. This causes low blood sugar levels and a person may experience excessive sweating, headache and dizziness.The U.S. FDA has recently approved injectable glucagon to treat severe hypoglycaemia in people aged 6 and above. The product is available in the form of a prefilled syringe with an auto-injector for hassle-free administration. Severe untreated hypoglycaemia may cause seizure, slipping into a coma and even death. The product has been found to increase blood sugar levels that dropped to 20 mg/dL, in 45 minutes. It is currently being studied for administration under the skin and as a part of the artificial pancreas system.
