摘要
目的:研究含有不同促透剂的硝苯地平纳米乳(NFNE)的体外透皮吸收特性,为硝苯地平透皮制剂研发奠定基础。方法:采用Franz扩散池法,在硝苯地平纳米乳中添加油溶性的氮酮、油酸或者水溶性的季铵化程度不同的N-三甲基壳聚糖(TMC20、TMC40、TMC60)作为促透剂,考察其体外透皮特性。结果:硝苯地平纳米乳体外透皮效果优于硝苯地平(NF)。各促透剂对NFNE的促透效果顺序依次为:氮酮>油酸>TMC60>TMC40>TMC20,而水溶性促透剂起效较快。结论:硝苯地平纳米乳中脂溶性促透剂促透效果强,而水溶性促透剂起效较快。
Objective : To study the in vitro transdermal permeability of nifedipine nanoemulsion (NFNE) containing different per- meation enhancers to lay foundation for the development of transdermal nifedipine preparation. Methods: Franz diffusion cells were used to study the transdermal enhancement of NFNE with different transdermal enhancers ( Azone, oleic acid, TMC20, TMC40, TMC60). Results: The in vitro transdermal effect of NFNE was better than that of nifedipine (NF). The order of in vitro transdermal permeation enhancement was as follows: azone 〉 oleic acid 〉 TMC60 〉 TMCA0 〉 TMC20, while the water-soluble transdermal permeation enhancers had faster effect. Conclusion: For NFNE, fat-soluble transdermal permeation enhancers have better effect.
