The present disclosure provides a once-daily water-soluble pharmaceutically active formulation for oral administration. In certain embodiments, the composition comprises a water-soluble pharmaceutically active organic compound incorporated into a small particulate, each particulate having a core of the water-soluble pharmaceutically active organic compound or an acceptable salt thereof in reversible association with a pharmaceutically acceptable drug-binding polymer. The core of the composition being surrounded by an insoluble water permeable membrane that is capable of delaying the dissolution of the pharmaceutically active compound therewithin and providing for extended release of the pharmaceutically active compound. In some embodiments, the formulation of the invention are designed to extend release of the pharmaceutically active organic compound for about 3 hours to about 8 hours, thereby enabling preparation of an extended release formulation for any pharmaceutically active compound with a half-life of from about 16 hours to about 21 hours.
本公开提供了一种用于口服的每日一次水溶性药用活性制剂。在某些实施方案中,该组合物包括掺入小颗粒中的水溶性药用活性有机化合物,每个颗粒都有一个水溶性药用活性有机化合物或其可接受盐的核心,该核心与药学上可接受的药物结合聚合物可逆结合。组合物的核心由不溶性透水膜包围,该膜能够延迟其中的药用活性化合物的溶解,并延长药用活性化合物的释放时间。在某些实施方案中,本发明的制剂可将药用活性有机化合物的释放时间延长约 3 小时至约 8 小时,从而能够制备半衰期为约 16 小时至约 21 小时的任何药用活性化合物的缓释制剂。
