Abstract:
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.
