摘要

Background Attention-deficit/hyperactivity disorder(ADHD)is a common behavioural disorder in childhood.The psychostimulant methylphenidate hydrochloride(MPH)is one of the major pharmacological options for ADHD.MPH is known to result,on average,in a small increase in arterial blood pressure(BP).However,there are few clinical data regarding theindividual influences of MPH on BP among children and adolescents with ADHD.According to the European Union-wide standardised patient information sheet for MPH,BP changes>10 mm Hg compared with baseline values are Common'(ie,≥1%to<10%)in children and adolescents with ADHD during MPH therapy.Aim To investigate the frequency and individual severity of BP changes in children and adolescents with ADHD during the first 6 months of new MPH therapy.Methods In this study,44(77%male)children and adolescents(mean age(SD)9.13(1.86)years)with a diagnosis of ADHD according to the International Classification of Diseases,tenth revision,underwent ambulatory BP monitoring before and during the first 6 months of routine MPH therapy.Exclusion criteria were pre-existing MPH therapy and other medications that potentially influence BP or interfere with MPH.The noninterventional study was conducted prospectively at 10 paediatric cardiology centres in Germany and Austria.Results After beginning MPH therapy,34%of participants(99%Cl 15.52%to 52.66%)had BP increases/decreases>10 mm Hg.The mean changes in systolic BP and diastolic BP were 0.87 mm Hg(95%Cl-1.75 mm Hg to 3.48 mm Hg)and 1.96 mm Hg(95%Cl 0.21 mm Hg to 3.7 mm Hg),respectively.The proportion of participants with initial prehypertension/hypertension was 54.55%.Conclusions In our sample with a high baseline rate of prehypertension/hypertension,BP changes>10 mm Hg during MPH therapy were more frequent than those indicated by the patient information sheet.Moreover,individual BP changes,including increases and decreases>10 mm Hg,resulted in a small average BP increase in the sample,thus reflecting neither the severity nor the direction of indiv
