Objective To investigate the efficacy of indapamide/felodipine combination in decreasing blood pressure in elderly patients with hypertension.Methods A total of 150 consecutive elderly cases of hypertension,average age (65.4 ± 3.6) years,were randomized into 3 groups:indapamide group (1.5 mg/d),felodipine group (5 mg/d),and indapamide (1.5 mg/d)/felodipine (5 mg/d) combination group,with 50 in each group.The treatment duration was 3 months.The average 24-hour,daytime and night-time systolic blood pressure/diastolic blood pressure and systolic blood pressure/diastolic blood pressure load,as well as mean heart rate,were determined at baseline and after 3 months.Results The average 24-hour,daytime and night-time systolic blood pressure/diastolic blood pressure,and blood pressure load were significantly decreased in all groups after treatment for 3 months,which was more significant in combination group than in single drug treatment group.The mean heart rate showed no significant change after 3 months of treatment.Conclusion Combination of calcium antagonist with long-acting diuretics at low dose provides substantial and stable antihypertensive benefit,and has few side effects.The regimen is strongly recommended for elderly patients with hypertension.?更多
