摘要
固体药物的溶解/溶出度、吸湿性和机械性质对药物生物利用度、处方工艺及稳定性等方面有深远影响。晶体药物理化性质与其内在晶体结构密切相关,药物晶体工程可以从分子水平改变药物晶体结构和修饰药物的理化性质,具有提高药物产品性能的潜质。本文从多晶型、无定形/共无定形和共晶等方面综述了晶体工程学技术对药物水溶性、吸湿性和机械性质的改善,为其在改善药物理化性质和提高成药性方面的应用提供参考。
The solubility/dissolution,hygroscopicity and mechanical properties of drug candidates have a profound effect on oral bioavailability,processability and stability.The physicochemical properties of crystalline drug are closely related to inner crystal structure.Crystal engineering technologies,as strategies of altering the crystal structure and tailoring physicochemical properties at molecular level,possess the potential of enhancing the pharmaceutical performance of product.The current article reviewed the modification of drug solubility/dissolution,hygroscopicity and mechanical properties by crystal engineering technologies through polymorphic selection,amorphization/co-amorphization,as well as co-crystallization,which provided a reference for the applications of pharmaceutical crystallography in improving physicochemical properties and druggability.
