Mechanism Of Action
Side Effect Profile
Prior Approvals
Other Research
GLP-1 receptor agonists, such as those similar to Orforglipron, mimic the incretin hormone GLP-1, which is naturally released after eating. They enhance insulin secretion, reduce glucagon levels, slow gastric emptying, and increase feelings of fullness. These actions collectively help reduce food intake and promote weight loss, making them effective for managing obesity by addressing both metabolic and appetite-related factors.
