crystalline forms for sodium salt of 5-amino-2,3dihydrophthalazine-1,4-dione, pharmaceutical preparations containing the same and process for producing said forms. the invention relates to the provision of two new crystalline forms i and ii for the sodium salt of 5-amino-2,3-dihydrophthalazine-1,4-dine. surprisingly, form i and form ii have been found to have different immunological effects. this advantageous property is useful for immunospecific applications. in editing, both forms have advantageous physicochemical properties, which are useful in the production, further processing and/or use of a pharmaceutical preparation of form I or form ii or a mixture of both. |
