肥猪片中除主药甲基硫氧嘧啶外,尚含其他赋形药,因此造成检验上的困难。应用英美药典规定的硷量法测定,终点不明显,测定结果不精确。有的药厂应用定氮法测定,但因含量甚微,定氮操作过于冗繁,亦不合理想。为了提高肥猪片检验工作效率,我厂利用甲基硫氧嘧啶能溶于硷和能与硝酸银产生沉淀的特性,研究出一种新的测定肥猪片含量的广法,试验结
Fat pig tablets in addition to the main drug methylthiouracil, it contains other excipients, resulting in inspection difficulties. Application of the United States and the United States Pharmacopoeia determination of the amount of alkali method, the end is not obvious, the measurement results are not accurate. Some pharmaceutical companies determine the use of nitrogen determination, but because of the content is very small, fixed nitrogen operation is too cumbersome, but also not ideal. In order to improve the work efficiency of the fat swine test, I plant the use of methylthiouracil soluble in alkaline and can precipitate with silver nitrate properties, developed a new method for the determination of fat swine tablets, test method
