Abstract;The number of patients with atherosclerotic diseases is increasing, and diabetes mellitus and hypertension are known risk factors of atherosclerotic diseases. Furthermore, oxidative stress contributes to the onset and deterioration of atherosclerosis. We investigated the effect of a calcium channel antagonist, benidipine hydrochloride, on brachial-ankle pulse wave velocity (baPWV), as an index of arterial stiffness and the urinary excretion of 8-hydroxy-2'-deoxy-guanosine (8-OHdG), as an index of oxidative stress. Benidipine hydrochloride (4-8 mg/day) treatment for six months significantly decreased systolic blood pressure, diastolic blood pressure, mean blood pressure and pulse pressure. Furthermore, baPWV and the urinary excretion of 8-OHdG were significantly decreased by benidipine treatment. Our results suggest that benidipine may improve atherosclerosis and oxidative stress in hypertensive patients with type 2 diabetes mellitus, leading to inhibiting cardiovascular diseases.
