Zusammenfassung:	The present invention relates to crystalline forms of gabapentin and processes for preparing the same. The present invention particularly relates to crystalline forms of gabapentin form II and Form IIB. The invention also relates to gabapentin form IA and form IB. The gabapentin forms IA and IB are hydrated forma that contain about 20% of water by weight which corresponds to hemipentahydrate. The present invention also relates to the process for preparing these crystalline forms of gabapentin. La présente invention concerne des formes cristallines de la Gabapentine et des procédés pour leur préparation. La présente invention concerne en particulier des formes cristallines de la Gabapentine de forme II et de forme IIB. L'invention concerne également la forme IA et la forme IB de la Gabapentine. Les formes IA et IB de la Gabapentine sont des formes hydratées qui contiennent environ 20 % d'eau en poids qui correspond à un hémipentahydrate. La présente invention concerne également le procédé de préparation de ces formes cristallines de la Gabapentine.
