  Purpose

The purpose of this study is to determine the effectiveness of candesartan cilexetil in preventing hypertension in people with high normal blood pressure. Patients will be randomized to either Candesartan or placebo for an initial 2-year period followed by a second 2-year period of placebo for all patients.

Further study details as provided by AstraZeneca:

Primary Outcome Measures:
  • To determine whether candesartan cilexetil 16 mg compared to placebo reduces the crude incidence of hypertension in a population with high normal BP evaluated after a 4-year study period consisting of 2 years of double-blind treatment followed by 2 years

Secondary Outcome Measures:
  • To evaluate the reduction in BP after 2 years treatment with candesartan cilexetil 16 mg vs placebo in patients with high normal BP.
  • To evaluate the incidence of hypertension after 2 years treatment with candesartan cilexetil 16 mg vs placebo in patients with high normal BP.
  • To evaluate Health-related Quality of Life yearly during 2 years treatment with candesartan cilexetil 16mg vs placebo and yearly during a 2-year follow up period in patients with high normal BP.

Estimated Enrollment: 1000
Study Start Date: July 1998
Study Completion Date: October 2005
Primary Completion Date: October 2005 (Final data collection date for primary outcome measure)
