透皮吸收的理化模型常用体外法(in vitro)来研究,它又可分为模拟皮肤扩散法、标准静态扩散室法和流通扩散室法。前者是用中间充满十四酸异丙酯的两层滤膜充当皮肤,后两种是用动物皮肤。标准静态扩散室接收液保持相对稳定,随着扩散时间的延长,接收室内药 Transcutaneous absorption of physical and chemical models commonly used in vitro (in vitro) to study, it can be divided into simulated skin diffusion method, the standard static diffusion chamber method and the flow of diffusion chamber method. The former is a middle layer of isopropyl myristate two layers of filter to act as the skin, the latter two are used animal skin. Standard static diffusion chamber receiving liquid to maintain relatively stable, with the extension of the diffusion time, receiving indoor medicine
