Zusammenfassung:The invention provides an acetazolamide sustained-release capsule and a preparation method thereof. Contents of the acetazolamide sustained-release capsule are acetazolamide sustained-release micropellets, a wax material is used in the sustained-release micropellets, wet pellets are obtained through wet granulation-extrusion rounding, and the pellets are dried at a temperature close to a melting point of the wax material, so that micropellet particles have the sustained-release characteristics. The obtained acetazolamide sustained-release capsule is a sustained-release preparation which is taken once a day, and compared with a quick-release preparation, the acetazolamide sustained-release capsule has the advantages that the daily administration times and side effects are reduced, and the patient compliance is improved. 本发明提供了一种乙酰唑胺缓释胶囊及其制备方法,所述乙酰唑胺缓释胶囊内容物为乙酰唑胺缓释微丸,缓释微丸中使用了蜡质材料,通过湿法制粒-挤出滚圆得到湿丸并在接近蜡质材料熔点的温度干燥,使微丸颗粒获得缓释特性。所得乙酰唑胺缓释胶囊为每日服用一次的缓释制剂,与速释制剂相比,减少了日服药次数及副作用,提高了患者依从性。
