Title
(EN) PARTICLE SIZE REDUCTION OF AN ANTIMUSCARINIC COMPOUND
(FR) RÉDUCTION DE LA TAILLE DE PARTICULE D'UN COMPOSÉ ANTIMUSCARINIQUE
Abstract
(EN)
The present invention relates to a process for preparing a crystalline micronised particulate of a glycopyrronium salt. The process involves suspending the drug in a water immiscible anti-solvent in which the drug has little or no solubility and micronizing the suspension. The resulting drug particles are physically stable with regard to agglomeration and/or aggregation on storage.
(FR)
La présente invention concerne un procédé de préparation de particules micronisées cristallines d'un sel de glycopyrronium. Le procédé comprend la suspension du médicament dans un anti-solvant non miscible avec l'eau dans lequel le médicament présente une solubilité faible ou nulle, et la micronisation de la suspension. Les particules de médicament résultantes sont physiquement stables au regard de l'agglomération et/ou de l'agrégation pendant le stockage.
