Treatment of Pediatric Hypertension With Altace Trial

Study Overview
=================
Brief Summary
-----------------
Ramipril is an ACE inhibitor that has been marketed in the US for the treatment of hypertension since 1991. It has been shown to be effective in reducing both systolic and diastolic blood pressure in adults when used once daily. ACE inhibitors are frequently used to treat hypertension in children, however ramipril has not been extensively tested in children, and information regarding the efficacy and safety would therefore be of benefit to children. This study is designed to demonstrate the efficacy and safety of ramipril in the treatment of hypertension in children ages 6 through 16 years.

Detailed Description
-----------------
In adults, common side effects include persistent dry mouth, dizziness, fatigue, and headache. Rare cases of angioedema have been reported. When used in pregnancy during the second and third trimesters, ACE inhibitors can cause injury and even death to the developing fetus. When pregnancy is detected, ramipril should be discontinued as soon as possible. Ramipril is contraindicated in patients who are hypersensitive to the product or have a history of angioedema related to previous treatment with an ACE inhibitor.

Eligibility Criteria
-----------------
Inclusion criteria: Males or females age 6 to 16 years. All female subjects ≥ 8 years of age must have a negative urine pregnancy test and must use an acceptable method of contraception, including abstinence, a barrier method (diaphragm or condom), Depo-Provera, or an oral contraceptive, for the duration of the study. Weight ≥ 20 kg. Parents/guardians must be able to demonstrate their ability to use the home blood pressure device to monitor blood pressure. Sitting systolic blood pressure or sitting diastolic blood pressure ≥ the 95th percentile for age, gender and height; or diabetes mellitus or chronic renal insufficiency (as evidenced by GFR 40-70 mL/min/1.73 m2) and a sitting systolic blood pressure or sitting diastolic blood pressure ≥ the 90th percentile for age, gender, and height. Exclusion criteria: Severe hypertension documented by (1) Sitting systolic blood pressure or sitting diastolic blood pressure more than 20 mmHg above the 95th percentile for age, gender, and height without antihypertensive therapy, (2) Sitting systolic blood pressure or sitting diastolic blood pressure more than 12 mmHg above the 95th percentile for age, gender, and height while receiving active therapy, or (3) hypertensive encephalopathy within the previous 5 months. Currently receiving more than one antihypertensive medication including: ACE inhibitors, angiotensin receptor inhibitors, beta blockers, calcium channel blockers, diuretics. Receiving lithium, potassium supplements, monoamine oxidase inhibitors, or major tranquilizers (Note: Stimulant medications for behavioral disorders, corticosteroids, and non-steroidal anti-inflammatory agents for chronic pain management are permitted during the trial provided the subject's dosage is anticipated to remain unchanged throughout the duration of the study.) 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.
