This study is designed as an open label study. After a 2-week placebo run-in phase, qualified patients will be administered with telmisartan 80mg for 2 weeks, then forcefully titrated to telmisartan 80 mg and hydrochlorothiazide 12.5 mg fixed dose combination for 6 weeks. 24 hour ABPM will be performed at the end of placebo run-in period (baseline) and after 8 weeks of active treatment.
The primary analyses will be the calculation of trough to peak ratios (T/P ratios) for DBP and SBP. The T/P ratio will be calculated on the basis of changes in hourly means (related to dosing time) from baseline (DeltaHM). Trough is defined as the mean of the last three hours of the 24-hour dosing interval. Peak is the greatest reduction in hourly means in hours 2 to 8 after dosing. Thus, T/P is calculated as T/P = mean(DeltaHM22 - DeltaHM24)/min (DeltaHM2 - DeltaHM8).
To assess trough/peak ratio of once daily Micardis plus by 24 ABPM in patients with mild to moderate essential hypertension.
