PHENOLIC ACID SALTS OF GABAPENTIN IN LIQUID AND/OR SEMI-SOLID DOSAGE FORMS AND METHODS OF USE

摘要

The present invention relates to pharmaceutical compositions of gabapentin tannate, processes for production of those compositions and methods of use of those compositions. The present invention provides a novel process for preparation of the tannate salt of gabapentin in liquid or semi-solid dosage form for human and veterinary pharmaceutical use. Tannate salts of active pharmaceutical ingredients are used in sustained release applications and to improve certain organoleptic properties such as taste. The process may utilize either natural or synthetic tannic acid.
