Illustration showing an inactivated GLP-1 receptor (blue, bottom left) next to a semaglutide agonist (red) and an activated GLP-1 receptor (bottom right) binding to a semaglutide agonist. Semaglutidel is a GLP-1 receptor agonist, a type of drug that mimics the function of natural GLP-1 hormones. These medications work by binding to GLP-1 receptors throughout the body and stimulating insulin secretion, inhibiting glucagon secretion, and slowing down gastric emptying. This leads to improved blood sugar control, making it an effective treatment option for type 2 diabetes.
