Abstract

<P>L'invention concerne une forme polymorphe cristalline exceptionnelle de flunisolide obtenue en mettant une des autres formes polymorphes du flunisolide solide en contact avec un liquide approprié dans lequel le flunisolide n'est pratiquement pas soluble, en particulier, le << Fréon 12 >> ou le << Fréon 114 >>, ou encore en recristallisant la forme cristalline exceptionnelle dans un solvant approprié tel que le chlorure de méthylène. <P> The invention relates to an exceptional crystalline polymorphic form of flunisolide obtained by bringing one of the other polymorphic forms of flunisolide solid into contact with a suitable liquid wherein the flunisolide is substantially not soluble, in particular, Freon << 12 >> or << >> Freon 114, or recrystallizing the exceptional crystalline form in a suitable solvent such as methylene chloride. Cette forme cristalline est stable dans des aérosols tels que des mélanges de Fréons. This crystalline form is stable in aerosols such as mixtures of Freons. </P><P>Application au traitement des troubles respiratoires.</P> </ P> <P> is useful for treating respiratory disorders. </ P>
