國內(nèi)外七廠家羅紅霉素在兩種介質(zhì)中的溶出度考察

1、國內(nèi)外七廠家羅紅霉素在兩種介質(zhì)中的溶出度考察            摘要目的：比較國內(nèi)外7廠家羅紅霉素在兩種介質(zhì)中的體外溶出度。方法：采用紫外分光光度法測定7廠家羅紅霉素的含量和在兩種不同介質(zhì)中的溶出度。結(jié)果：7廠家羅紅霉素在人工胃液中溶出度均不符合要求，在人工腸液中有2家產(chǎn)品不符合要求。結(jié)論：羅紅霉素在兩種介質(zhì)中溶出度有很大差異，各廠家之同的產(chǎn)品溶出度也存在差異，選用羅紅霉素時注意產(chǎn)品質(zhì)量。關(guān)鍵詞：羅紅霉素溶出度介質(zhì)固體口服制劑的溶出度是控制藥品質(zhì)量、有效保證體內(nèi)生物利用度

2、的重要指標(biāo)。羅紅霉素是新型大壞內(nèi)酯類抗生素，與紅霉素有相似抗菌譜，藥物動力學(xué)優(yōu)于紅霉素。由于羅紅霉素具強(qiáng)疏水性，制劑工藝將影響其在體內(nèi)的溶出和吸收?，F(xiàn)在市場上羅紅霉素產(chǎn)品比較多，包括不同的劑型，中國藥典（95年版）未收載羅紅霉素，各生產(chǎn)廠家測定溶出度時均采用地方標(biāo)準(zhǔn)，溶出介質(zhì)不同，為此我們對國內(nèi)外7廠家羅紅霉素在兩種介質(zhì)中溶出度迸行了考察。我們利用硫酸呈色反應(yīng)，采用比色法測定羅紅霉素的溶出量。1實驗材料和儀器1.1試樣與拭劑羅紅霉素對照品（效價970u）；羅紅霉素片劑（A：香港某廠家提供； B：國內(nèi)某廠家提供；C：國內(nèi)某廠家提供；D：國外某廠家提供；規(guī)格均是150mg）；羅紅霉素膠囊（E：國內(nèi)

3、某廠家提供；F：國內(nèi)某廠家提供1；G：國內(nèi)某廠家提供，規(guī)格均是150mg）試劑均為分析純。1.2儀器天津無線電廠ZRS-4智能溶出試驗儀，北京市通用儀器設(shè)備公司TU-1221型紫外可見分光光度計。2方法與結(jié)果    表1七廠家羅紅霉素累積溶出度結(jié)果（%，X±SD，n=6）     廠家    時間(min)    含量 %    5    10&#
