中药是指在中医理论指导下应用的药物。中药传统剂型是汤剂,是我国应用最早、最广泛的一种剂型,汤剂适应中医的辨证施治、随证加减的原则,具备简单易行、吸收快、能迅速发挥药效的优点。但是,汤剂也存在一些不足之处,如煎液体积较大、味苦,服用、携带不方便;易发霉、发酵、不能久贮;不宜大量制备,也不利于及时抢救危重患者等。因此,近年来广大中医药研究者对汤剂进行了有效的剂型改革,出现了如中药合剂、口服液、片剂、胶囊剂、颗粒剂、注射剂等,都是尽量保留汤剂药效,并在克服其缺点的基础上发展起来的中成药新剂型。然而,由于中药成分复杂,物质基础研究薄弱等原因,中成药的质量控制问题一直困扰着中药制剂的发展,影响着中药制剂现代化和国际化的进程。 Chinese medicine refers to the application of medicine under the guidance of Chinese medicine theory. The traditional Chinese medicine dosage form is a decoction, which is the earliest and most widely used form in our country. The decoction adapted to the syndrome differentiation of traditional Chinese medicine, with the principle of addition and subtraction, has the advantages of simple and easy absorption, rapid absorption and rapid efficacy . However, the decoction also has some shortcomings, such as large decoction volume, bitter, taking, carrying inconvenient; easy moldy, fermentation, can not be long storage; not suitable for large-scale preparation, but also not conducive to the timely rescue of critically ill patients. Therefore, in recent years, many Chinese medicine researchers have carried out effective dosage form reform on decoction, such as Chinese traditional medicine, oral liquid, tablet, capsule, granule, injection, etc., all try their best to retain the efficacy of decoction In overcoming its shortcomings on the basis of the development of new proprietary Chinese medicine formulations. However, due to the complexity of traditional Chinese medicine and the weak basic research, the quality control of traditional Chinese medicine has plagued the development of traditional Chinese medicine preparations and affected the modernization and internationalization of traditional Chinese medicine preparations.
