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.
