四苯硼钠法测定西咪替丁片的含量

Determination of cimetidin tablets by sodium tetraphenylboron method

本文采用四苯硼钠法测定西咪替丁片的含量，方法简便、快速、准确，回收率为９９．８８＋０．４３％。经测定四个厂家４批样品的含量，并与药典方法（非水滴定法）进行了比较，结果一致。

A sodium tetraphenylboron method has been studied to determine the contents of cimetidin tablets. The average recoveries was 99.88 ±0.42%. This method is smiple,rapid and accurate. The method provides consistent results comparable to those obtained from the assay defined in the CP(1990 edition)for four batches of tablets.
