HOW DO ANTIDIABETIC GLUCAGON-LIKE PEPTIDE-1 AGONISTS WORK?

Antidiabetic glucagon-like peptide-1 agonists (also known as GLP-1 agonists) are a class of drugs used with a proper diet and exercise to control high blood sugar in people with type 2 diabetes mellitus (T2DM) and obesity. T2DM is a long-term medical condition in which the body does not use insulin normally and, therefore, cannot control the amount of sugar in the blood. Controlling high blood sugar helps in preventing kidney damage, blindness, nerve problems, loss of limbs, and sexual function problems and may also reduce the risk of a heart attack or stroke. Obesity is an abnormal or excessive fat accumulation that presents a health risk. A body mass index (BMI is calculated by considering a person’s weight and height to measure body size) of more than 25 is considered overweight and more than 30 is considered obese.

GLP-1 agonists are synthetic (man-made) hormones that resemble and act like GLP-1 which is one of the gut hormones involved in controlling the blood sugar.

GLP-1 agonists are not used to treat insulin-dependent or type 1 diabetes (a condition in which the body does not produce insulin and therefore cannot control the amount of sugar in the blood) and diabetic ketoacidosis (increased ketones in the blood or urine).

GLP-1 agonists are available as injectable powder for suspension and a solution (liquid) in a prefilled dosing pen to be injected subcutaneously (under the skin) in the stomach, thigh, or upper arm

GLP-1 agonists work in the following ways:

  • They belong to a class of drugs called "incretin mimetics" because these drugs mimic the effects of incretins. 
  • Incretins are hormones that are produced and released into the blood by the intestine in response to food
  • GLP-1 is an incretin, one of the gut hormones, involved in controlling blood sugar, mainly acting on the insulin that the body produces after meals.
  • GLP-1 is responsible for various functions such as:
    • Stimulation of insulin from the pancreas in response to food
    • Slowing down the absorption of glucose from the gut
    • Reduces gastric emptying
    • Inhibits the action of glucagon, a hormone that increases glucose production by the liver
    • Reduces appetite and promotes satiety or stomach fullness
