Abstract: La présente invention concerne de nouveaux faciès cristallins d'oxcarbazépine, plus particulièrement des faciès d'oxcarbazépine B, C, D et E, ainsi que leurs procédés de préparation. On prépare le faciès B en faisant évaporer les solvants d'une solution d'oxcarbazépine dans du toluène et du dichlorométhane ou on obtient ce faciès en refroidissant immédiatement la solution d'oxcarbazépine et de toluène. Le refroidissement de cette même solution à une vitesse inférieure, mais toujours assez rapide, débouche sur le faciès C d'oxcarbazépine. Le refroidissement de cette même solution à une vitesse encore plus inférieure engendre un autre faciès, le faciès D d'oxcarbazépine. On obtient le faciès E d'oxcarbazépine, un solvate de chloroforme, en précipitant une solution d'oxcarbazépine et du chloroforme. Cette invention a aussi trait à des procédés de conversion d'un des nouveaux faciès cristallins d'oxcarbazépine découverts en une autre faciès, y compris le faciès A, élaboré avec une technique antérieure. Ces conversions peuvent se produire au cours du stockage à température ambiante, du chauffage d'un faciès particulier ou du traitement avec un solvant protique.
