Final answer:
Metformin (Glucophage) is the medication used to treat Type II diabetes. It improves insulin sensitivity and reduces liver glucose production.
Step-by-step explanation:
Among the medications listed, Metformin (Glucophage) is used in the treatment of Type II diabetes. Metformin works by improving the sensitivity of body tissues to insulin and reducing the amount of glucose produced by the liver. It is a first-line medication recommended for the treatment of Type II diabetes and is usually prescribed when lifestyle changes such as diet modification and exercise are insufficient to control blood glucose levels. Other medications listed, such as Thioridazine, Furosemide, Cimetidine, and Simvastatin, are used for different medical conditions and are not used in the management of Type II diabetes.
