Abstract: front page image
(EN) A lubiprostone crystal, its preparation process, its pharmaceutical composition or kit, and its use for the preparation of a pharmaceutical composition for treating gastroenteropathy, especial constipation. The characteristic peaks of 2ϑ reflection angle in X-ray powder diffraction spectra of the crystal contain 14.6±0.2°, 17.0±0.2° and 19.6±0.2°. The crystal has the advantages of high purity, stable property, and convenient storage and usage compared with amorphous lubiprostone.
(FR) L'invention porte sur un cristal de lubiprostone, son procédé de préparation, sa composition pharmaceutique ou son coffret et son utilisation pour la préparation d'une composition pharmaceutique pour le traitement d'une gastroentéropathie, en particulier de la constipation. Les pics caractéristiques d'angle de réflexion 2θ dans des spectres de diffraction des rayons X sur poudre du cristal contiennent 14,6 ± 0,2°, 17,0 ± 0,2° et 19,6 ± 0,2°. Le cristal présente les avantages d'une pureté élevée, d'une propriété stable et d'un stockage et d'un usage commodes par comparaison avec la lubiprostone amorphe.
