在驱避剂的研究中,目前的核心问题是解决减少吸收和蒸发,延长保护时间,提高使用效果。实践表明,研制药物的缓释剂型是解决以上问题的一种非常有效的立法。聚合物制剂就是一种非常好的缓释剂型,它在驱避剂上的应用已经得到很好的证实,取得了比较满意的效果。进一步开发这类制剂在卫生杀虫缓释剂中的应用有着非常现实的意义。本文仅对聚合物控释的原理及途径作一探讨。
In the research of repellent, the core problem at present is to solve the problems of reducing absorption and evaporation, prolonging the protection time and improving the using effect. Practice shows that the development of drug sustained-release formulations is to solve the above problem is a very effective legislation. Polymer formulation is a very good sustained release dosage form, its application in repellent has been well confirmed, and achieved satisfactory results. The further development of such preparations in the application of sustained release insecticide has a very realistic significance. This article only on polymer controlled release of the principles and ways to make a discussion.
