摘要: A process for forming multiparticulates of azithromycin and a controlled release dosage form comprising multiparticulates of azithromycin and a pharmaceutically acceptable excipient are disclosed. The dosage form decreases the incidence and/or severity of GI side effects relative to currently available immediate release azithromycin dosage forms that deliver an equivalent dose. The dosage forms operate by effecting azithromycin release at a rate sufficiently slow to ameliorate side effects, yet sufficiently fast to achieve good bioavailability.
摘要翻译: 公开了形成阿奇霉素的多颗粒和包含阿奇霉素和药学上可接受的赋形剂的多颗粒的控制释放剂型的方法。 相对于递送相当剂量的目前可用的即时释放阿奇霉素剂型,剂型降低了GI副作用的发生率和/或严重性。 剂型通过以足够缓慢的速度实施阿奇霉素释放来改善副作用,但足够快以达到良好的生物利用度。
