Conditions

Diabetes Mellitus, Type 2

Brief summary

Type 2 diabetes mellitus (T2DM) is a progressive metabolic disorder in which a substantial number of patients cannot attain treatment target despite antidiabetic drugs. The renin-angiotensin system (RAS) has recently been implicated in the development of insulin resistance and impaired glucose metabolism. This study investigates the effect of adding RAS inhibitors to standard antidiabetic therapy in patients with T2DM. The primary outcome measure is the change in serum glycosylated hemoglobin A1c after 24 weeks of treatment. Secondary outcomes measures include changes in plasma lipid profile and blood pressure after treatment.
