20080233187 | Method of Production of Fine-Crystalline Mixture Containing Non-Steroid Anti-Inflammatory Drug, Fine-Crystalline Mixture Obtainable by this Method and Solid Pharmaceutical Composition Containing this Mixture - 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. | 09-25-2008 |
20090032248 | METHOD FOR PRODUCTION, SUBSTITUTION, OR MINING OF GAS HYDRATE - A gas hydrate is produced by injecting guest molecules into voids in a layer of which temperature and pressure condition allows the guest molecules to cause to form hydrate, in a form of emulsion where liquid of the guest molecules is dispersed in water as minute particles having a size of less than a size of voids, and thereby dispersing the guest molecules uniformly into the voids in the layer. | 02-05-2009 |
20090156660 | PHARMACEUTICAL COMPOSITION CONTAINING TAXANE DERIVATIVE DESTINED FOR THE PREPARATION OF AN INFUSION SOLUTION, METHOD OF PREPARATION THEREOF AND USE THEREOF - A pharmaceutical composition containing a taxane derivative, destined for the preparation of an infusion solution for administration to patients, containing a concentrate consisting of a pharmaceutically effective amount of docetaxel, a suitable solvent, which is preferably ethanol, a surfactant, which is polysorbate 80 and a pharmaceutically effective amount of an appropriate buffer; and optionally a co-solvent, consisting of an aqueous solution of a pharmaceutically effective amount of polysorbate 80 and optionally suitable organic solvent and/or a pharmaceutically effective amount of an appropriate buffer. This composition shows an excellent chemical and physical stability. The invention includes also a method of preparation of the pharmaceutical composition and the use thereof. | 06-18-2009 |
