The key feature of the Sulfonylureas class of medications is that they increase insulin release from the pancreas. Sulfonylureas work by stimulating the beta cells in the pancreas to secrete more insulin, which helps to lower blood glucose levels. This mechanism is particularly useful for patients with type 2 diabetes when their insulin production is insufficient to meet their metabolic needs.

While some other options touch on aspects of diabetes treatment, they do not accurately represent the primary function of Sulfonylureas. These medications are typically not available solely in liquid form, as they generally come in tablet form. Although Sulfonylureas may be considered in diabetes management, they are not first-line medications; metformin is usually preferred as the initial treatment for type 2 diabetes. Additionally, while Sulfonylureas can help manage blood sugar levels, they do not replace the need for insulin therapy in patients whose diabetes progresses or who have type 1 diabetes, where exogenous insulin is necessary for survival.
