Semaglutide
Definition: A highly successful, FDA-approved GLP-1 receptor agonist that regulates blood sugar, slows gastric emptying, and significantly reduces appetite.
What is Semaglutide?
Semaglutide is a synthetic, long-acting analog of human Glucagon-Like Peptide-1 (GLP-1), a hormone naturally secreted by the intestines in response to food intake. Unlike endogenous GLP-1, which has a half-life of only a few minutes, Semaglutide is structurally modified to resist degradation by the enzyme DPP-4, allowing for a prolonged therapeutic effect in managing blood glucose and body weight.
How does Semaglutide work?
Semaglutide acts as a potent GLP-1 receptor agonist. It stimulates insulin secretion from pancreatic beta cells in a glucose-dependent manner while suppressing glucagon release. Crucially for weight management, it acts on the hypothalamus to enhance satiety and reduce food cravings. It also slows gastric emptying, leading to a prolonged feeling of fullness after eating.
Primary Documented Uses
- Treatment of Type 2 Diabetes (Ozempic, Rybelsus)
- Chronic Weight Management in obesity or overweight individuals (Wegovy)
- Reducing the risk of major adverse cardiovascular events (MACE)
Research Summary
Semaglutide is backed by extensive, high-quality human clinical data. The landmark STEP (Semaglutide Treatment Effect in People with Obesity) clinical trial program demonstrated that weekly subcutaneous injections of 2.4 mg Semaglutide led to an average weight loss of approximately 15% of body weight over 68 weeks. It also showed significant cardiovascular risk reduction in patients with type 2 diabetes and obesity.
Legal and Regulatory Status
Semaglutide is fully FDA-approved for Type 2 Diabetes and chronic weight management. It is a prescription-only medication. Due to widespread shortages, qualified 503A compounding pharmacies have been permitted to compound custom formulations of Semaglutide under strict FDA guidelines, though this status is subject to change as brand-name supply stabilizes.
