经皮给药系统亟待解决的关键问题是提高药物的透皮吸收,中药挥发油作为一大类性质优良的透皮吸收促进剂,不仅能促进药物的透皮吸收,对皮肤刺激性小,而且还能起到一定的治疗效果,与透皮吸收的药物产生协同作用,但中药挥发油自身溶解度差,还存在不稳定的问题。目前应用于挥发油透皮促渗的制剂技术包括贴剂、包合物、凝胶膏剂、凝胶剂、微乳等,单独或组合使用能不同程度地增加挥发油的溶解度,提高透皮促渗效果。对目前中药挥发油透皮促渗的制剂技术进行综述,并对其今后的研究方向进行初步探讨。

[Abstract]
The critical problem to be solved in the study of transdermal drug delivery system is to improve the transdermal penetration of drugs through the skin. Most essential oils from Chinese material medica, considered as a large class of penetration enhancers, possess enhanced percutaneous absorption, minor skin irritation, certain therapeutic efficacy, and a synergistic effect with transdermal drugs. However, the essential oils have poor solubility and unstable problems. Some special preparations, including patch, clathrate, gel plasters, gels, microemulsion, and so on, can increase the solubility of the essential oils, improve the effect of permeability, and can significantly boost the stability of the essential oils. In this paper, the techniques of the related preparations on essential oil from Chinese materia medica should be reviewed, and the research direction of the later stage should be discussed.
