改善中药口服生物利用度的剂型设计的研究

化学药物存在生物利用度低的问题,中药也必然存在同样的问题,但是中药是多成分的集合体,其剂型设计必须符合中药的特点才能够改善中药的吸收利用。传统中药剂型以丸、散、膏、丹、汤为主,存在服药量大,疗效差等问题;随着中药现代化的进程,在中药新型制剂的研究方面取得了显著的成果,但是却不能使中医药理论和现代制剂理论有机融合,中药制剂的开发必然要考虑到中药的特点。该文从中药多组分的角度出发,采用多元化制剂技术,建立了中药多元释药系统。

Study on dosage form design for improving oral bioavailability of traditional Chinese medicines

Both chemical drugs and traditional Chinese medicines have the problem of low bioavailability. However, as traditional Chinese medicines are a multi-component complex, their dosage forms are required to be designed in line with their characteristics, in order to improve the bioavailability of traditional Chinese medicines. Traditional Chinese medicines are mostly prepared into pill, powder, paste, elixir and decoction, but with such drawbacks as high administration dose and poor efficacy. With the process of modernization of traditional Chinese medicines, new-type preparations have be developed and made outstanding achievements. However, they fail to make an organic integration between traditional Chinese medicine theories and modern preparation theories. Characteristics of traditional Chinese medicines are required to be taken into account during the development of traditional Chinese medicines. In the article, multi-component preparation technology was adopted to establish a multi-component drug release system of traditional Chinese medicines on the basis of multiple components of traditional Chinese medicines.
