Title: Prevention of Hypertension in Patients With Pre-hypertension: PREVER-prevention Study
Brief Summary: The incidence of hypertension in individuals with pre-hypertension was 80% in ten years in a study conducted in Southern Brazil. The effectiveness of non-drug interventions to prevent hypertension is low in the long term. It may be hypothesized that a population-based drug intervention could reduce relevantly the burden of hypertension and cardiovascular disease.

Diuretics are at least as efficacious as other blood pressure-lowering drugs, are well tolerated, have longer duration of action and the advantage of very low cost to be used in a population intervention. Chlorthalidone is the more efficacious agent. Its main limitation is to induce hypokalemia in a proportion of patients, an adverse effect that can be antagonized by a potassium-sparing diuretic, as amiloride.

A study with this objective is therefore recommendable in Brazil, in order to support a plan of precocious intervention in individuals with pre-hypertension. Such a study was demanded and funded by the Health and Technology Ministries in Brazil.

Exclusion Criteria:

1. A definite contraindication to treatment with an ACE inhibitor or a thiazide-like diuretic

5. A definite indication for long-term full-dose or bed-time insulin therapy
6. Participation in a trial within the month prior to the Registration Visit or current participation in another trial

Other potential reasons for ineligibility include:

* High probability of non-adherence to study treatment or follow-up
* Current clinical instability (e.g. a major cerebral or coronary event or sight-threatening retinopathy or macular oedema within the previous few weeks)
* Life threatening non-vascular disease other than diabetes and its complications
* Moderate or severe dementia
* Major disability that is likely to prevent regular attendance at study clinics

Final decisions about eligibility were made at the discretion of the study investigator and the potential study participant, in the light of any requirements or guidance from local ethics committees and other regulatory bodies.
