In the context of diabetes management, which class of medication do biguanides belong to?

Biguanides are classified as oral antihyperglycemics, primarily exemplified by metformin. This class of medications is used to manage blood glucose levels in patients with type 2 diabetes. Metformin works by decreasing hepatic glucose production, increasing insulin sensitivity, and enhancing peripheral glucose uptake and utilization. By addressing hyperglycemia through these mechanisms, biguanides facilitate better glycemic control without the typical risk of weight gain associated with some other diabetes medications.

Insulin sensitizers, while one of the actions of biguanides, does not encompass the full functional capability of the class. Injectable glucagon-like peptide (GLP-1) agonists and sodium-glucose cotransporter 2 (SGLT2) inhibitors represent entirely different classes of diabetes medications with distinct mechanisms of action. GLP-1 agonists enhance insulin secretion in response to meals and inhibit glucagon release, while SGLT2 inhibitors promote glucose excretion in the urine. Thus, biguanides specifically fall under the category of oral antihyperglycemics, as they are taken orally to manage blood sugar levels efficiently.
