Metformin is commonly used to manage Type 2 Diabetes because it primarily functions by improving insulin sensitivity and reducing hepatic glucose production. This leads to better overall glycemic control, which is essential in managing Type 2 Diabetes, where the body either resists the effects of insulin or doesn't produce enough insulin to maintain normal glucose levels.

Insulin is typically used in Type 1 Diabetes and sometimes in advanced cases of Type 2 Diabetes when other medications are no longer effective. Aspirin, while important in cardiovascular protection and management, does not address blood sugar levels or diabetes management directly. Atorvastatin is a cholesterol-lowering medication that may be prescribed to patients with diabetes to help reduce cardiovascular risks but is not used for managing blood glucose levels specifically. Hence, Metformin stands out as the first-line therapy for Type 2 Diabetes management.
