What is one of the brand names associated with biguanides?

Biguanides are a class of oral antidiabetic medications primarily used to manage type 2 diabetes mellitus. One of the most well-known brand names associated with biguanides is Glucophage, which contains the active ingredient metformin. Metformin works by decreasing hepatic glucose production, increasing insulin sensitivity, and enhancing peripheral glucose uptake, which ultimately helps to lower blood sugar levels in patients with type 2 diabetes.

The other brand names mentioned do not belong to the biguanide class. Glargine (Lantus) is a long-acting insulin, Avandia is a brand name for rosiglitazone, a thiazolidinedione, and Lantus is also an insulin product. These medications serve different mechanisms and purposes in diabetes management, emphasizing the distinct role that Glucophage plays as a representative of biguanides.
