Amlodipine has potential advantages in children since it can be dissolved into a liquid preparation and has a long elimination half-life, allowing for once-daily administration. The objective of this study was to compare the efficacy and compliance of amlodipine with that of standard long-acting calcium channel blockers (felodipine or nifedipine) in hypertensive children. A randomized, prospective, crossover study of 11 hypertensive children (9-17 years of age, 10 renal transplant patients) was performed with electronic monitoring of compliance. Each treatment arm was 30 days. No significant differences were observed in mean systolic (SBP) and diastolic blood pressures (DBP) between amlodipine and the other calcium channel blockers. Using 24-h blood pressure monitoring there were no significant differences over each drug treatment period in both mean day-time and night-time SBP and DBP. Patient compliance was similar in both the amlodipine and the nifedipine/felodipine treatment periods. These data suggest that amlodipine is as effective in pediatric nephrology patients as nifedipine and felodipine. Amlodipine may be optimally suited for treatment of young children because at present it is the only calcium channel blocker which can be administered once daily as a liquid preparation.
