Semaglutide 5mg
Summary Description:Semaglutide is a synthetic, long-acting glucagon-like peptide-1 receptor agonist (GLP-1 RA) used primarily for the treatment of type 2 diabetes and, at higher doses, for chronic weight management in adults with overweight or obesity. It mimics endogenous GLP-1, enhancing glucose-dependent insulin secretion, decreasing glucagon secretion, and significantly reducing appetite and energy intake, which leads to clinically meaningful weight loss. Structurally, semaglutide is a modified peptide analog of human GLP-1, designed to resist enzymatic degradation and prolong its biological half-life, allowing for once-weekly subcutaneous injection.
