A Trial Comparing MICARDIS® (Telmisartan) and COZAAR® / LORZAAR® (Losartan) in Patients With Mild-to-Moderate Hypertension Using Ambulatory Blood Pressure Monitoring (ABPM)
- Conditions
- Hypertension
- Interventions
- Drug: High dose of COZAAR® / LORZAAR®, once dailyDrug: High dose of MICARDIS®, once dailyDrug: Low dose of COZAAR® / LORZAAR®, once dailyDrug: Low dose of MICARDIS®, once dailyDrug: Placebo
- Registration Number
- NCT02200653
- Lead Sponsor
- Boehringer Ingelheim
- Brief Summary
The primary aim of the trial is to compare the influence of MICARDIS® (telmisartan) and COZAAR® / LORZAAR® (losartan) in lowering ambulatory diastolic blood pressure (DBP) during the last 6 hours of the 24-hour dosing interval as measured by ABPM. Secondary objectives include evaluations of: 1) change from baseline in mean systolic blood pressure (SBP) during the last 6 hours of the 24-hour dosing interval as measured by ABPM, 2) changes from baseline in SBP and DBP during other periods during the 24-hour ABPM profile, 3) changes from baseline in mean seated trough SBP and DBP as measured by manual cuff sphygmomanometer, and 4) responder rates based on both ABPM and trough cuff blood pressure
