氯化钾缓释片(简称缓钾片)是北京某医院药房试制并应用于临床的一种新剂型,据报道,使用原子吸收法可测定其不同时间的释放度。为了采用较简便的仪器和方法作为缓钾片释放度的常规检查,本文试用钾离子选择性电极对缓钾片在一定时间内释放出氯化钾的含 Potassium chloride sustained release tablets (referred to as slow potassium tablets) is a Beijing pharmacy pharmacy trial and applied to clinical a new dosage form, according to reports, the use of atomic absorption method can be measured at different times of release. In order to use more convenient instruments and methods as a routine examination of the release of slow-release tablets, this paper attempts to use potassium-selective electrodes to release potassium chloride from the slow-release tablets for a certain period of time
