摘　　要：药物的多晶型对制剂的稳定性、溶出度及生物利用度等有着不可忽视的影响,有的甚至带来毒副作用,是影响药品质量的重要因素之一。因此,仅定性分析原料药或制剂中的晶型不能满足药品的质量控制要求。为了测定原料药或制剂中有效晶型的含量,从而确保制剂的疗效,需要建立适当的多晶型定量方法,其中包括X-射线粉末衍射法、傅里叶变换拉曼光谱法、中红外光谱法、近红外光谱法、太赫兹光谱法、固态核磁共振法和差示扫描量热法等技术。本文综述了近10年来这些晶型定量方法的研究进展。Polymorphism of drug is known to influence the stability,dissolution,bioavailability and other performance characteristics of the products.Therefore,the crystal form of the drug must be identified and determined in order to ensure consistent product performance.Even if the identification and characterization of crystal forms are performed thoroughly and the effective crystal form is selected for preparation,it is important to ensure that the effective crystal form in the final product remains unchanged.Therefore,it is essential to quantitate the content of the effective crystal form in the product to control the quality and performance of them.X-ray powder diffraction,FT-Raman,mid-IR,near-IR,terahertz pulsed spectroscopy,solid-state NMR spectroscopy,and DSC are the quantitative methods of crystal form used in the recent 10 years.This review briefly highlights the basic principles and the progress of these methods and discusses the perspective as they apply to pharmaceutical research and development.
