Diurnal Variation in Hypertensive Stroke Patients

April 11, 2013 updated by: Hanmi Pharmaceutical Company Limited

Comparison of the Effects of Amlodipine and Losartan on Blood Pressure and Diurnal Variation in Hypertensive Stroke Patients

This study was conducted to evaluate and compare the effectiveness of Amodipin® (amlodipine camsylate) with that of Cozaar® (losartan potassium) in hypertensive patients with an acute ischemic stroke by measuring their 24-hour ambulatory BP (ABP).
