Byetta (exenatide; AstraZeneca) is a member of the glucagon-like peptide-1 (GLP-1) agonist class. GLP-1 agonists are incretin mimetics, mimicking the endogenous gut hormone GLP-1, which stimulates insulin-secreting beta cells in the pancreas. This triggers glucose-dependent insulin secretion, suppressing glucagon secretion, and thereby decreases plasma glucose levels. The major advantage of this class is the associated weight loss, as obesity is a common co-morbidity among type 2 diabetes patients. GLP-1 agonists also delay gastric emptying, thus increasing satiety and suppressing appetite.
The drug was developed as part of a joint venture between AstraZeneca and Bristol-Myers Squibb. However, AstraZeneca has taken full ownership and marketing responsibilities after buying its partner’s share of the venture.
