1.Male or female patients ? 18 years
2.Patients with essential hypertension:
-At Visit 1, untreated patients must have an MSDBP ? 100 mmHg and < 110 mmHg and treated patients need to have an MSDBP < 110 mmHg. Untreated patients can be included as soon as the safety laboratory parameters are available, but not at the day of Visit 1. This inclusion visit will be recorded as Visit 3 in the CRF.
-At Visit 2, patients previously treated for hypertension need to have an MSDBP ? 100 mmHg and < 110 mmHg for entry into the first treatment phase. Patients previously treated for hypertension who have an MSDBP < 100 mmHg at Visit 2 will continue the wash-out phase and will be again evaluated with regard to BP criteria at Visit 3. Untreated patients do not perform Visit 2.
-At Visit 3, which is not performed for patients who entered the first treatment phase already at Visit 2, patients need to have an MSDBP ? 100 mmHg and < 110 mmHg for entry into the first treatment phase.
-At Visit 4, all patients need to have an MSDBP ? 90 mmHg for entry into the second treatment phase

22.Unwillingness or inability to give informed consent
23.Study personnel or first degree relatives of investigator(s) must not be included in the study
