摘 要 目的:考察国内硝酸甘油片仿制制剂与参比制剂(原研药)的体外质量一致性。方法:参照硝酸甘油片进口药品注册标准
JX20010267测定硝酸甘油片1批参比制剂(A厂家)和4批仿制制剂(B、C、D、E厂家)中硝酸甘油和有关物质的含量。采用溶出度
测定方法中的桨法,转速为50 r/min,以高效液相色谱法测定上述5批制剂在4种不同溶出介质(pH 1.2盐酸溶液、pH 4.0醋酸盐缓
冲液、pH 6.8磷酸盐缓冲液、水)中10 min内的溶出量,计算累积溶出度,绘制溶出曲线,并以2、5、8 min时的累积溶出度计算相似
因子(f2 ),评价溶出曲线的相似性。结果:A、B、C、D、E厂家制剂中硝酸甘油含量分别为99.8%、98.3%、94.0%、93.3%、96.7%(n=
2),有关物质含量分别为0.46%、0.55%、0.63%、0.72%、0.49%(n=2)。以A厂家参比制剂为对照,在pH 1.2盐酸溶液中B、C、D、E
厂家仿制制剂的f2分别为74、28、25、67,在pH 4.0醋酸盐缓冲液中的f2分别为76、26、28、84,在pH 6.8磷酸盐缓冲液中的f2分别为
79、39、35、71,在水中的f2分别为69、32、37、62。结论:本方法适用于硝酸甘油片仿制制剂的体外质量一致性评价。与参比制剂比
较,C、D厂家的仿制制剂主药含量较低,体外溶出曲线不具有相似性。

ABSTRACT OBJECTIVE:To investigate the in vitro quality consistency of domestic Nitroglycerin tablet imitative preparation
and reference preparation (original drug). METHODS:The contents of nitroglycerin and related substances in 1 batch of
Nitroglycerin tablet reference preparation(manufacturer A)and 4 batches of imitative preparation(manufacturer B,C,D,E)
were determined according to Nitroglycerin Tablet Import Drugs Registration Standard JX20010267. The paddle method of
dissolution determination method was adopted,with the rotating speed of 50 r/min. HPLC method was adopted to determine the
dissolution amount of 5 batches of above preparations in 4 kinds of dissolution mediums(pH 1.2 hydrochloric acid solution,pH
4.0 acetate buffer solution,pH 6.8 phosphate buffer solution,water) within 10 min.The accumulative dissolution rate was
calculated,and dissolution curves of samples were drawn.The similarity of the dissolution curves was evaluated by calculating
similarity factor(f2 )of 2,5,8 min accumulative dissolution rate. RESULTS:The contents of nitroglycerin in the preparations
from manufacturer A,B,C,D,E were 99.8%,98.3%,94.0%,93.3%,96.7%,respectively(n=2);the contents of related
substance were 0.46%,0.55%,0.63%,0.72%,0.49%,respectively(n=2). Using reference preparation of manufacturer A as
control,f2 of imitative preparation from manufacturer B,C,D,E were 74,28,25,67 in pH 1.2 hydrochloric acid solution;76,
26,28,84 in pH 4.0 acetate buffer solution;79,39,35,71 in pH 6.8 phosphate buffer solution;69,32,37,62 in water,
respectively. CONCLUSIONS:The method is suitable for in vitro quality consistency evaluation of Nitroglycerin table timitative
preparation. Compared with reference preparation,the contents of main components in the imitative preparations from manufacturer
C,D are lower;in vitro dissolution curves of those imitative preparation are not similar to reference preparation.
