Clinical trial of extended-release felodipine in pediatric essential hypertension.

摘要

Essential hypertension in pediatric patients may require pharmacological treatment. There is a need for efficacious, safe, and well-tolerated antihypertensive agents with a once-a-day dosing regimen in children and adolescents. The aim of the trial was to evaluate the dose-response and tolerability of the dihydropyridine calcium channel blocker, felodipine extended-release tablets (felodipine ER), given once daily to pediatric patients with essential hypertension. A randomized double-blind, parallel-group, multi-center clinical study comparing felodipine ER (2.5, 5, or 10 mg once daily) and placebo was performed on pediatric patients with a baseline systolic (SBP) or diastolic blood pressure (DBP) above the 95th percentile for age, sex, and height. Of 133 randomized patients, 128 (96.2%) completed the 3 weeks of double-blind treatment. The study population included 50% children 6-12 years of age or Tanner stage
