The present invention concerns a process for the purification of macrolide antibiotics. More specifically it concerns a process for the purification of macrolide antibiotics that result in a white powder. The powder remains white also after some time of storage. The process of the present invention is performed by dissolving the macrolide antibiotics, e.g. commercial vancomycin hydrochloride, in water and subjecting the solution to ultrafiltration with a membrane having nominal retention lower than 30,000 Da, preferably of 10,000 Da. The purified solution is preferably concentrated by reversed osmosis and then lyophilized at the optimized conditions of pressure and temperature to obtain a white powder.

La présente invention concerne un procédé de purification d'antibiotiques macrolides. Plus spécifiquement, elle concerne un procédé de purification d'antibiotiques macrolides qui donne une poudre blanche. La poudre reste blanche même après un certain temps de stockage. Le procédé de la présente invention s'effectue en dissolvant les antibiotiques macrolides, par exemple du chlorhydrate de vancomycine du commerce, dans de l'eau et en soumettant la solution à une ultrafiltration avec une membrane ayant une rétention nominale inférieure à 30 000 Da, de préférence de 10 000 Da. La solution purifiée est de préférence concentrée par osmose inverse puis lyophilisée dans des conditions de pression et de température optimisées afin d'obtenir une poudre blanche.
