    • The present invention provides a method for preparing a spray-dried, compressible granular formulation for preparing pharmaceutical tablets in which essentially water-insoluble, acidic, amphoteric, and basic pharmaceutically active agents are converted to more water-soluble salts which are granulated with hydrolyzed cellulose, drug-containing slurries, the resulting granulations, capsules containing granulations, and pharmaceutical tablets compressed from such granules. In these formulations there is employed from 1% to 85% by weight of the pharmaceutically active agent and its salt form, from 5% to 99% of hydrolyzed cellulose, based on the dry weight of the granulation, and optionally, conventional granulation and/or tableting additives such as surfactants, disintegrants, and antiadherents/flow aids. Said tablets have significantly increased dissolution of the pharmaceutically active agent at the pH of the gastrointestinal tract in comparison with the unconverted free pharmaceutically active agent.
    • 本发明提供了一种制备用于制备药物片剂的喷雾干燥的可压缩颗粒制剂的方法,其中基本上不溶于水的,酸性的,两性的和碱性的药物活性剂转化为更多的水溶性盐,其被水解的纤维素 ,含药浆液,所得颗粒,含有颗粒的胶囊和从该颗粒压制的药物片剂。 在这些制剂中,基于造粒物的干重,使用1%至85%重量的药学活性剂及其盐形式,5%至99%的水解纤维素,以及任选的常规制粒和/ 或压片添加剂如表面活性剂,崩解剂和抗粘附剂/流动助剂。 与未转化的游离药物活性剂相比,所述片剂在胃肠道的pH下显着增加药物活性剂的溶出度。
