Semaglutide is a medication extensively used to manage type 2 diabetes effectively. It belongs to the class of GLP-1 receptor agonists and aids in controlling blood sugar levels by stimulating insulin release and reducing excessive glucagon production. Additionally, semaglutide promotes weight loss and has shown promise in cardiovascular risk reduction.
What Is Semaglutide?
Semaglutide is a prominent medication belonging to the class of drugs known as glucagon-like peptide-1 receptor agonists or GLP-1 receptor agonists.1 These drugs are designed to mimic the effects of the naturally occurring GLP-1 hormone, which regulates blood sugar levels in the body. Semaglutide primarily acts by enhancing insulin secretion, inhibiting glucagon release, slowing digestion, and reducing appetite. This comprehensive physiological approach makes it a practical option for managing type 2 diabetes and obesity.
Notably, semaglutide is not available as a generic medication but under specific brand names such as Ozempic, Wegovy, and Rybelsus.1 These brand names refer to different formulations and dosages of semaglutide tailored for different medical purposes. Ozempic is FDA-approved to treat type 2 diabetes, providing a means to improve glycemic control in adults. Wegovy is FDA-approved for weight loss and weight management.
Rybelsus is also FDA-approved for managing type 2 diabetes. The approval by the U.S. Food and Drug Administration (FDA) signifies that the benefits and risks of these medications have been thoroughly evaluated through rigorous clinical trials and regulatory processes, thus validating their safety and efficacy for their intended uses.1

Marketed as Wegovy when used for weight loss, it belongs to the class of GLP-1 receptor agonists. These drugs imitate the actions of GLP-1, a natural hormone regulating blood sugar.
