Title (EN) PROCESS FOR CONTROLLING CRYSTAL STRUCTURE OF RISEDRONATE
(FR) PROCEDE DE COMMANDE DE LA STRUCTURE CRISTALLINE DU RISEDRONATE
Abstract: front page image
(EN)The present invention relates to a process for controlling the crystal form of 3-pyridyl-1-hydroxy-ethylidene-1,1-bisphosphonic acid salt (Risedronate). The process employs a pH adjustment step to induce the proper hydrate form and thereby avoiding inadvertent nucleation of undesired hydrate forms.
(FR)La présente invention concerne un procédé de commande de la forme cristalline de sel d'acide 3-pyridyl-1-hydroxy-éthylidène-1,1-bisphosphonique (risédronate). Ledit procédé fait intervenir une étape de réglage du pH visant à obtenir la forme hydrate adaptée et à éviter toute nucléation accidentielle de formes hydrates non souhaitées.
