Byetta
Byetta, also known as exenatide, is a medication used to manage type 2 diabetes. It works by mimicking a natural hormone called glucagon-like peptide-1 (GLP-1) to help regulate blood sugar levels.
Chemical Name and Structure
Byetta’s chemical name is exenatide. It is a synthetic peptide, meaning it is a chain of amino acids. Its structure closely resembles that of GLP-1, a naturally occurring hormone produced in the intestines. This structural similarity allows Byetta to bind to and activate GLP-1 receptors in the body, mimicking the actions of the natural hormone.
Mechanism of Action
Byetta works by mimicking the actions of GLP-1, a hormone that plays a crucial role in regulating blood sugar levels. When Byetta binds to GLP-1 receptors, it triggers a cascade of events that ultimately lead to:
- Increased insulin secretion: Byetta stimulates the pancreas to release more insulin, especially after meals, when blood sugar levels are high. This helps lower blood sugar levels.
- Decreased glucagon secretion: Byetta also suppresses the release of glucagon, another hormone that raises blood sugar levels. This further contributes to lowering blood sugar levels.
- Delayed gastric emptying: Byetta slows down the rate at which food leaves the stomach. This helps regulate blood sugar levels by preventing rapid spikes in blood sugar after meals.
- Increased satiety: Byetta promotes feelings of fullness, which can help with weight management, a crucial aspect of managing type 2 diabetes.
Pharmaceutical Form and Dosage
Byetta is available as a solution for injection. It is typically administered twice daily, 60 minutes before the morning and evening meals. The dosage is usually 5 mcg or 10 mcg, depending on the individual’s needs and response to treatment.
