The results of the present study of the pharmacokinetics of articaine in children show serum concentrations comparable to those in adults. The maximum values are distinctly lower with the 2% articaine solution. The t max found in our investigation was distinctly earlier than in comparable investigations on adults, whereas the plasma clearance was increased. There is no need to fix a lower mg/kg articaine dose limit for children because of age-related differences in the pharmacokinetics. The use of 2% articaine in pediatric dentistry is particularly advantageous because of the lower C max and the shorter half-life.
本次关于儿童阿替卡因药代动力学的研究结果表明,其血清浓度与成人相当。2%阿替卡因溶液的最大值明显较低。我们研究中发现的达峰时间明显早于针对成人的类似研究,而血浆清除率有所增加。由于药代动力学存在与年龄相关的差异,无需为儿童设定较低的阿替卡因毫克/千克剂量限制。在儿童牙科中使用2%阿替卡因特别有利,因为其最大血药浓度较低且半衰期较短。
