Abstract: | AbstractJapanese patients with uncontrolled essential hypertension received single-blind losartan 50?mg/hydrochlorothiazide 12.5?mg (L50/H12.5) for 8 weeks. Patients whose blood pressure (BP) remained uncontrolled were randomized double-blind to fixed-dose losartan 50?mg/hydrochlorothiazide 12.5?mg/amlodipine 5?mg (L50/H12.5/A5) or L50/H12.5 for 8 weeks followed by open-label L50/H12.5/A5 for 44 weeks. Adverse events were assessed. After 8 weeks, diastolic and systolic BP were reduced significantly more with L50/H12.5/A5 versus L50/H12.5 (both p?0.001). Mean changes in diastolic and systolic BP were sustained for 44 weeks. L50/H12.5/A5 was well-tolerated and improved BP significantly versus L50/H12.5 in Japanese patients with uncontrolled essential hypertension.Trial registration: ClinicalTrials.gov identifier: NCT01299376. |
