聚合物异相成核对加巴喷丁晶型的控制和选择

The crystalline polymorph control and selection of gabapentin with polymer heteronuclei

药物晶型对药物的物理、化学和生物利用度等诸多性能具有重要的影响。本文通过聚合物异相成核研究了加巴喷丁晶型的培养方法,以X-射线粉末衍射、红外光谱、DSC分析等方法对培养的加巴喷丁晶型进行了分析和表征。结果表明,聚合物异相成核是一种对加巴喷丁进行晶型选择和控制的有效方法,本文不但培养了加巴喷丁所有已知的晶型,而且还发现了一种新的加巴喷丁晶型。

The pharmaceutical properties, including the physical and chemical properties, and the bioavailability are greatly influenced by their polymorphism. In this paper the polymer heteronuclei were used to produce the gabapentin polymorphs that were characterized by X-ray powder diffraction, FT-IR and DSC. The results indicated that the polymer heteronuclei are an effective method to control and select the gabapentin polymorphism. One new polymorph of gabapentin was found besides all known gabapentin polymorphs.
