Detailed Description:

Information is needed on the treatment of hypertension in children and adolescents with antihypertensive drugs like ramipril. The study will assess the safety and blood pressure effects of several doses of the antihypertensive drug ramipril in children and adolescents age 6-16 years. Approximately 450 children will be given placebo, or 1 of the 3 doses of ramipril. The treatment assigned will be done by chance, like flipping a coin. Approximately 120 study centers throughout the world will participate in the trial.

Each child will complete a 1- to 4-week Screening Period where they will stop taking their current blood pressure lowering drug(s), a 4-week Treatment Period where they will receive placebo or one of the ramipril doses, and a Follow-up visit 1 week after completion of the Treatment Period. Children diagnosed with hypertension according to the fourth report on the diagnosis, evaluation and treatment of high blood pressure in children and adolescents (U.S. report), will be included in the study if their blood pressure meets certain values.

Each child will complete a minimum of 6 and up to 9 clinic visits over the course of the study during which procedures and assessments of blood pressure and safety will be performed. In addition, a child's parents/guardians will be instructed to measure their child's blood pressure at home between clinic visits.

A planned interim analysis was performed after approximately 240 subjects completed the trial. The study was stopped, as permitted by protocol, after the analysis.

Criteria

Inclusion Criteria:

Previous, documented diagnosis of hypertension, or newly diagnosed hypertension according to the fourth report on the diagnosis, evaluation and treatment of high blood pressure in children and adolescents (United States). SiSBP greater than or equal to the 95th percentile for age, gender, and height.
The subject can be safely withdrawn from antihypertensive medications during the screening period, and if given placebo during the treatment period in the judgment of the Investigator.
The subject is male or female age 6 to 16 years (inclusive), and weighs greater than or equal to 20 kg.
Female subjects greater than or equal to 12 years of age, or who have had greater than or equal to 1 menstruation must: (a) have a negative serum pregnancy test at screening (i.e., subject is not pregnant), (b) not be lactating, and (c) use an acceptable method of contraception.
Parents/guardians are able to demonstrate their ability to (a) use a home blood pressure monitor supplied for the study to monitor their child's blood pressure, and (2) mix and administer a liquid dose of study drug if needed.

Exclusion Criteria:

Bilateral renal artery stenosis.
Uncorrected coarctation of the aorta or corrected coarctation with a right arm/right leg blood pressure gradient greater than 10 mmHg.
Severe hypertension.
Renal transplantation or other previous solid organ transplantation less than 6 months prior to entering the study.
Subjects with nephrotic syndrome not on stable maintenance therapy of prednisone or cyclosporine.
A history of cardiomyopathy, clinically significant structural heart disease, or atrioventricular conduction disturbance, sick sinus syndrome, atrial flutter, atrial fibrillation, clinically significant bradycardia or an accessory bypass tract, or clinical symptoms of congestive heart failure.
Clinically significant hematologic, hepatobiliary, or renal disease including a Schwartz formula GFR less than 40 mL/min/1.73 m2, and/or serum potassium (K+) greater than 5.5 mEq/L.
