| 摘要 |
The invention concerns a method of production of a fine-crystalline mixture containing a non-steroid anti-inflammatory drug and an auxiliary substance, wherein a coarse-crystalline substance from the group of non-steroid anti-inflammatory drugs is dissolved in a solvent at an increased temperature, the solution is subsequently distributed at rapid chilling into a cooling liquid containing the auxiliary substance, said cooling liquid being placed in an ice bath, and the product is then filtered off and dried. It further concerns the fine-crystalline mixture of the non-steroid anti-inflammatory drug and the auxiliary substance that can be obtained by the said method. The invention further concerns a solid pharmaceutical composition, having substantially improved dissolution properties, which contains 60 to 78% w/w of the fine-crystalline mixture, 17 to 40% w/w of microcrystalline cellulose, colloidal silicon dioxide in an amount of up to 0.3% w/w, a disintegrant in an amount of up to 4% w/w and optionally a surface active compound in an amount of up to 0.1% w/w. This solid pharmaceutical composition can be filled into capsules or used for the preparation of tablets.
