摘要:
Crystalline forms of the p38 kinase inhibitor N-(2-hydroxyacetyl)-5-(4-piperidyl)-4-(4-pyrimidinyl)-3-(4-chlorophenyl)pyrazole are provided. These crystalline forms include (a) a first anhydrous crystalline form possessing improved physical stability relative to other solid-state forms of the compound; (b) a second anhydrous crystalline form possessing unique properties relative to other solid-state forms of the compound; (c) a third anhydrous crystalline form possessing unique properties relative to other solid-state forms of the compound; and (d) solvated crystalline forms, hydrated crystalline forms, and crystalline salt forms of the compound that are useful, for example, as intermediate solid-state forms in the preparation of other crystalline forms of the compound. Also provided are combinations and pharmaceutical compositions comprising at least one of these crystalline forms, processes for preparing these crystalline forms and for preparing compositions comprising these crystalline forms, and methods for the prophylaxis and/or treatment of a p38 kinase-mediated condition comprising administering to a subject a therapeutically effective amount of at least one of these crystalline forms.
摘要:
Pharmaceutical compositions are provided comprising one or more orally deliverable dose units, each comprising a selective cyclooxygenase-2 inhibitory compound of low water solubility in a therapeutically effective amount, wherein the compound is present in the form of solid particles, about 25% to 100% by weight of which are smaller than 1 micrometer. The compositions are useful in treatment or prophylaxis of cyclooxygenase-2 mediated conditions and disorders and have particular advantages where rapid onset of therapeutic effect is desired. The novel Form I and Form II crystalline forms of celecoxib are described. The crystalline forms have unique chemical and physical properties relative to other solid state forms of celecoxib and are characterized by their powder x-ray diffraction (PXRD) patterns, differential scanning calorimetric (DSC) thermograms, and other physical characterizations.
