Sulfonylureas are primarily used to treat Type II Diabetes. This class of medication works by stimulating the pancreas to release more insulin, which helps lower blood glucose levels. In patients with Type II Diabetes, the body often produces insulin but is resistant to its effects, making it less effective at controlling blood sugar levels. Sulfonylureas help overcome this resistance by increasing insulin secretion, thereby improving glycemic control.

These medications are not effective for Type I Diabetes, which is primarily characterized by an autoimmune destruction of insulin-producing beta cells in the pancreas, leading to little or no insulin production. Therefore, sulfonylureas would not be beneficial in managing this condition. Additionally, sulfonylureas are not indicated for treating hypertension or heart failure, as these conditions require different classes of medications that specifically target blood pressure regulation and heart function.
