  • Publication number: 20090149431
    Abstract: A novel crystalline form (Form L) of the aldosterone receptor antagonist drug eplerenone is provided having relatively high physical stability at normal temperatures of storage and use. Pharmaceutical compositions are also provided comprising Form L eplerenone, optionally accompanied by one or more other solid state forms of eplerenone, in a total unit dosage amount of eplerenone of about 10 to about 1000 mg, and further comprising one or more pharmaceutically acceptable excipients. Processes are provided for preparing Form L eplerenone and for preparing compositions comprising Form L eplerenone. A method for prophylaxis and/or treatment of an aldosterone-mediated condition or disorder is also provided, comprising administering to a subject a therapeutically effective amount of eplerenone, wherein at least a fraction of the eplerenone present is Form L eplerenone.

  • Patent number: 6872725
    Abstract: 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.

  • Publication number: 20020038021
    Abstract: A novel crystalline form (Form H) of the aldosterone receptor antagonist drug eplerenone is provided having a relatively rapid dissolution rate in aqueous media. Also provided are novel solvated crystalline forms of eplerenone that, when desolvated, can yield Form H eplerenone. Also provided is amorphous eplerenone. Pharmaceutical compositions are provided comprising Form H eplerenone, optionally accompanied by one or more other solid state forms of eplerenone, in a total unit dosage amount of eplerenone of about 10 to about 1000 mg, and further comprising one or more pharmaceutically acceptable excipients. Processes are provided for preparing Form H eplerenone and for preparing compositions comprising Form H eplerenone. A method for prophylaxis and/or treatment of an aldosterone-mediated condition or disorder is also provided, comprising administering to a subject a therapeutically effective amount of eplerenone, wherein at least a fraction of the eplerenone present is Form H eplerenone.
