摘要
目的:筛选天麻素经鼻给药制剂的吸收促进剂种类和用量。方法:采用HPLC测定天麻素含量,流动相乙腈-0.05%磷酸(3∶97),检测波长220 nm。采用Franz水平扩散池,以家兔鼻黏膜为渗透屏障,比较冰片、丙二醇、水溶性氮酮对天麻素经鼻给药制剂的促渗透效果,确定吸收促进剂种类和用量。结果:3种吸收促进剂均对天麻素经鼻给药制剂有促渗作用,5.0%水溶性氮酮的促渗效果最好,3 h内天麻素累积渗透量达3 470.54μg·cm-2,增渗倍数1.922。结论:5%氮酮可作为天麻素经鼻给药制剂的吸收促进剂。
Objective: To screen out species and amounts of absorption enhancer for intranasal administration preparations of gastrodin. Method: The content of gastrodin was determined by HPLC with mobile phase of acetonitrile-0.05% phosphoric acid(3:97) and detection wavelength at 220 nm.Improved Franz-type diffusion cell was adopted,with rabbit nasal mucosa partition as transdermal barrier,single factor tests were used to compare promoting penetration effect of borneol,propylene glycol and water-soluble azone on intranasal administration preparations of gastrodin,in order to determine kinds and amounts of absorption enhancer. Result: All of three absorption enhancers had promoting penetration effect on intranasal administration preparations of gastrodin,but 5% water-soluble azone was the best one,its cumulative permeation quantity was 3 470.54 μg·cm-2 in 3 h,enhancement ratio was 1.922. Conclusion: 5% Water-soluble azone could be as a absorption enhancer for intranasal administration preparations of gastrodin.
