Semaglutide
well-studiedA GLP-1 receptor agonist originally developed for type 2 diabetes, now the most prescribed weight loss medication worldwide.
Overview
Semaglutide is a glucagon-like peptide-1 (GLP-1) receptor agonist that mimics the incretin hormone GLP-1. It was developed by Novo Nordisk and is sold under brand names Ozempic (diabetes) and Wegovy (weight management). It works by increasing insulin secretion, decreasing glucagon secretion, slowing gastric emptying, and reducing appetite through central nervous system effects.
Clinical trials (STEP program) demonstrated average weight loss of 15-17% of body weight over 68 weeks. It has become one of the most significant pharmaceutical developments in obesity treatment, with global demand consistently outpacing supply.
