Study to Evaluate Efficacy of Micardis® (Telmisartan) and Valsartan in Patients With Mild-to-moderate Hypertension After Missing One Dose Using Ambulatory Blood Pressure Monitoring

A Prospective, Randomised, Double-blind, Double-dummy Trial to Compare the Efficacy of Micardis® (Telmisartan) (80 mg p.o. Once Daily) and Valsartan (160 mg p.o. Once Daily) in Patients With Mild-to-moderate Hypertension After Missing One Dose Using Ambulatory Blood Pressure Monitoring

The primary aim of the trial is to compare telmisartan 80 mg to valsartan 160 mg in lowering diastolic blood pressure in patients who missed a dose of their medication, as measured by ABPM (change from baseline in mean DBP over 24 hours), and to compare telmisartan 80 mg to valsartan 160 mg in lowering DBP during the last six hours of the dosing interval at the end of a 6 to 8-week treatment period, as measured by ABPM (change from baseline)
