Description
Byetta (exenatide) is a twice‑daily injectable GLP‑1 receptor agonist for adults with type 2 diabetes that lowers post‑meal blood sugar and may support modest weight loss; it requires careful use in people with kidney or severe gastrointestinal disease.
Byetta is the brand name for exenatide, an injectable GLP‑1 receptor agonist used as an add‑on treatment for adults with type 2 diabetes to improve glycaemic control when oral agents alone are insufficient.
How Byetta Works
Byetta stimulates glucose‑dependent insulin secretion, suppresses inappropriate glucagon release, and slows gastric emptying, which together reduce postprandial glucose spikes and can help with appetite control and weight management in some patients.
