摘要:
The non-hydrated gapapentine polymorph is obtained by desiccating by atomization or turbodrying an aqueous solution of gabapentine; the invention also relates to its use in order to obtain gabapentine appropriate for pharmaceutical use; disclosed is a method which comprises subjecting the polymorph to a crystallization process in solvents.
