摘要
目的 :研究糖衣对盐酸维拉帕米片含量测定的影响。方法 :采用紫外分光光度法 ,并进行配对设计的t检验。结果 :糖衣溶液在 2 0 0～ 4 0 0nm范围内无吸收 ,平均回收率为 99 16% (n =5 ) ,RSD为 0 5 5 %。P >0 0 5 (n =4 ) ,差别无显著性意义。结论 :糖衣对盐酸维拉帕米片的含量测定无干扰 ,可不剥糖衣进行该片的含量测定。
OBJECTIVE: To study the effect of sugarcoat on the determination of verapamil hydrochloride tablets METHOD: A ultraviolet spectrophotometer was used RESULT: Sugarcoat solution had no absorbance over the range 200 to 400 nm The average recovery of the assay was 99 16% ( n =5), and the RSD was 0 55% There was no remarkable difference between the two methods ( P >0 05) CONCLUSION: The sugarcoat had no effect on the determination of verapamil hydrochloride tablets
