We evaluated its anti-hypertensive effect and safety in mild to moderate hypertensive patients. Materials and MethodsCandesartan cilexetil, 8 mg or 16 mg, was administered once a day over 8 weeks period in the patients with mild to moderate hypertension 25 male, 26 female, mean age53.51.2 years. For safety evaluation, laboratory tests were performed before and after treatment with candesartan cilexetil. Changes in blood pressure, heart rate and electrocardiogram were also observed. Results1 The mean blood pressures in the sitting position were systolic 164.12.1 mmhg and diastolic 106.30.8 mmhg before treatment, which were lowered to 135.42.0 mmhg and 89.11.1 mmhg, repectively after 8 weeks of treatment p0.05. 2 Candesartan cilexetil had a significant dosedepen-dent antihypertensive effect for diastolic pressure in 35 patients (8 mg97.80.9 mmhg, 16 mg 91.31.1 mmhg, p0.05. 3 Heart rate was not significantly changed before and after treatment during the treatment with candesartan cilexetil 72.21.2/min vs. 72.01.3/minp0.05. 4 Laboratory tests revealed no significant abnormality by the treatment with candesartan cilexetil. 5 Left ventricular hypertrophy by ECG criteria detected in 3 cases disappeared after treatment with candesartan cilexetil. 6 No significant side effects were observed during the treatment period. ConclusionCandesartan cilexetil, 8 mg or 16 mg, once a day is an effective and well tolerated antihypertensive treatment. It has a significant dose-dependent antihypertensive effect.
