對(duì)照品或標(biāo)準(zhǔn)品混用,即將對(duì)照品或標(biāo)準(zhǔn)品用于不是其標(biāo)定方法的含量測定,是藥品檢驗(yàn)中經(jīng)常出現(xiàn)但未引起重視的一個(gè)問題[3]。盡管同一批對(duì)照品不同標(biāo)定方法的含量有很好的相關(guān)性,但并不*相同,有時(shí)差別會(huì)很大。如英國Glaxo公司提供的*酯對(duì)照品,HPLC標(biāo)定為96.9%,供含量測定用;UV為98.8%,供溶出度測定。雖然中國藥典凡例明確規(guī)定衛(wèi)生部所發(fā)對(duì)照品僅用于正文中所規(guī)定的分析方法。但由于:
?。?)衛(wèi)生部提供的對(duì)照品使用說明書不夠詳盡,大多無對(duì)照品質(zhì)量要求及標(biāo)定方法;
(2)對(duì)對(duì)照品或標(biāo)準(zhǔn)品的正確使用缺乏認(rèn)識(shí);
