Primary outcomePrimary: Change in Sitting Diastolic Blood Pressure (DBP) From Baseline to the End of the Study (From Baseline to 8 Weeks). — -3.3; -9.3; -7.7; -13.9 mm Hg
Summary
The aim is to compare the blood pressure lowering effect of the combination of candesartan cilexetil (candesartan) 32 mg and hydrochlorothiazide (HCT) 25 mg to that of candesartan 32 mg alone, HCT 25 mg alone and placebo in hypertensive adults.

Eligibility Criteria
Inclusion Criteria
- Patients will be eligible for enrolment into the study (Visit 1) if they fulfil all of the following criteria:
- Provision of signed Informed Consent
- Primary hypertension, untreated or treated with a maximum of 2 antihypertensive drugs (substances), which the patient and the physician are willing to withdraw at enrolment and replace with placebo.
- Mean sitting DBP 90-114 mmHg (value calculated in the eCRF) at Visits 1 and 2
- Patients will be eligible for randomisation (Visit 4) if they fulfil the following criterion:
- Mean sitting DBP of 90-114 mmHg (value calculated in the eCRF) at the end of the 4-week single-blind placebo run-in period. The run-in period should not be shorter than 4 weeks.
Exclusion Criteria
- Pregnant or lactating women, or women of childbearing potential not practising an adequate method of contraception eg, intrauterine device, oral contraception or progesterone implant. Pregnancy must be excluded by a negative pregnancy test at Visit 1.

- Aortic or mitral valve stenosis
- Cardiac failure requiring treatment
- Cardiac arrhythmia requiring treatment
- Gout
- Renal artery stenosis or kidney transplantation
- Intravascular volume depletion
- Hypersensitivity to any component of the investigational products or to any sulphonamide derived drugs
