Process of obtainment of racemic cetamine enantiomers; process of obtainment of pharmaceutically acceptable salts from racemic cetamine enantiomes and use of pharmaceutically acceptable salts obtained by means of said mentioned process

摘要

The present invention describes a new process for obtainment of the cetamine enantiomers, from the racemic cetamine resolutions with the aid of an agent of chiral resolution, which provides the selective crystallization of its enantiomers. The resolution agent is employed in special concentration conditions, which provides stability, reproducibility and high enantiomeric purity to the precipitated diasteromer salt, making feasible the industrial production of the S-cetamine and its pharmaceutically acceptable salts.
