About

To evaluate the efficacy of valsartan 160 mg/HCTZ 25 mg in patients not adequately responding to monotherapy with olmesartan medoxomil 40 mg or combination therapy with olmesartan medoxomil 20 mg plus HCTZ 12.5 mg by testing the hypothesis that valsartan 160 mg/HCTZ 25 mg significantly reduces the trough mean sitting diastolic blood pressure (MSDBP) after a 4-week treatment in the nonresponder population.

Enrollment: 212 patients

Sex: All

Ages: 18+ years old

Inclusion criteria

• Females must be either post-menopausal for one year, surgically sterile or using effective contraceptive methods (e.g. barrier method with spermicide, intra-uterine device, hormonal contraceptives).

• Patients with essential hypertension:

  • At Visit 1, untreated patients should have a MSDBP >100 mmHg and < 110 mmHg and treated patients need to have a 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 a MSDBP ≥ 100 mmHg and < 110 mmHg for entrance into the first treatment phase. Patients previously treated for hypertension who have a 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 a MSDBP >100 mmHg and < 110 mmHg for entrance into the first treatment phase.
  • At Visit 4, all patients need to have a MSDBP >90 mmHg for entrance into the second treatment phase.

Exclusion criteria

• MSDBP >110 mmHg or MSSBP >180 mmHg
• Pregnant or nursing women
• Inability to completely discontinue all antihypertensive medications safely for a period of up to 2 weeks, as required by the protocol

Other protocol-defined exclusion criteria may apply.
