氨茶碱贴剂经皮吸收及药代动力学研究
Transdermal Absorption and Pharmacokinetics of Aminophylline Transdermal Delivery System
-
摘要: 目的:研究氨茶碱贴剂对家兔在不同皮肤部位给药后的经皮吸收及药动学行为.方法:采用HPLC法测定血浆中氨茶碱的浓度,应用3P97实用药动学程序进行数据处理.结果:氨茶碱贴剂经背部肺腧穴和脾腧穴皮肤给药后,其血药浓度均高于背部非穴位给药,其中肺腧穴与非穴位相比有极显著性差异(P<0.01),脾腧穴与非穴位相比有显著性差异(P<0.05),肺腧穴与脾腧穴相比有显著性差异(P<0.05).氨茶碱体内吸收符合单室模型,一级吸收,血药浓度平稳,维持至少24 h释放.结论:氨茶碱在皮肤不同部位的经皮吸收存在差异,穴位给药有助于氨茶碱经皮吸收.Abstract: AIM:To investigate the transdermal absorption and pharmacokinetics of aminophylline transdermal delivery system (TDS) on acupuncture points of rabbit.METHOD: Aminophylline concentration in plasma was determined by HPLC.The pharmacokinetic parameters were
