  • 市售复方酮康唑乳膏包含酮康唑、硫酸新霉素和丙酸氯倍他索,是治疗浅部真菌感染的常用药物。其中,酮康唑是最常用的抗真菌药物,具有价格低、抗菌谱广、抗真菌活性强等优势。但细菌对硫酸新霉素易产生耐药性,可导致患者反复感染,难以根治,且丙酸氯倍他索不适合12岁以下儿童使用,副作用较多,可产生红斑、灼热、瘙痒等刺激症状,长期大面积用药可导致高血糖等[1-5]。针对上述问题,为改善市售产品的有效性和安全性,本课题组将硫酸新霉素替换为抗菌作用更强的莫匹罗星,将丙酸氯倍他索替换为副作用较少的糠酸莫米松,再结合酮康唑,制备新型复方酮康唑软膏,以提高患者的用药依从性[6-8]

    本研究采用反相高效液相色谱法同时测定复方酮康唑软膏中酮康唑、莫匹罗星和糠酸莫米松3种药效成分的含量,该方法目前未见有文献报道。本法简便,灵敏,分离度好,准确性高,可以为该制剂的质量标准研究提供依据。

  • AL204型电子天平(梅特勒-托利多仪器有限公司);TU-1901型紫外可见分光光度计(北京普析通用仪器有限责任公司);Agilent 1200型高效液相色谱仪(美国Agilent公司);Starter 2C型实验室pH计(奥豪斯仪器有限公司);KQ-800KDE型超声波清洗器(昆山市超声仪器有限公司)。

  • 酮康唑对照品(批号:100294-201203,含量99.4%)、莫匹罗星对照品(批号:130568-200501,含量94.2%)、糠酸莫米松对照品(批号:100930-201201,含量99.9%)均购自中国食品药品检定研究院;酮康唑原料药(批号:20130405)、莫匹罗星原料药(批号:20130301)、糠酸莫米松原料药(批号:20130228)均购自武汉鑫佳公司;聚乙二醇400和聚乙二醇3350(中国医药对外贸易公司)。

  • 分别取酮康唑、莫匹罗星和糠酸莫米松适量,精密称定,加流动相制备成适宜浓度的溶液,以相应的溶剂为空白溶液,在190~400 nm波长范围内进行紫外扫描,结果见图1

    图1可见,莫匹罗星在220 nm处具有最大吸收波长,糠酸莫米松在248 nm处具有最大吸收波长,酮康唑在203 nm和245.5 nm具有最大吸收波长,三者在220 nm与248 nm之间均有吸收,因在供试品中酮康唑和莫匹罗星的浓度均是糠酸莫米松的20倍,糠酸莫米松在220 nm处响应值较小,为保证3种药物能同时测定,确定酮康唑、莫匹罗星和糠酸莫米松的检测波长为248 nm。

  • 色谱柱:Intersil ODS-3柱(250 mm×4.6 mm,5 µm),流动相为甲醇-pH5.5磷酸盐缓冲液(65∶35),柱温45 ℃,流速1.0 ml/min,检测波长248 nm,进样量10 µl。理论塔板数以各组分峰计,均不低于5000,各色谱峰的分离度良好。

    莫匹罗星对照品溶液:取莫匹罗星20 mg,精密称定,置10 ml量瓶中,加入适量65%甲醇,超声使其完全溶解,加65%甲醇稀释至刻度,摇匀,得到莫匹罗星的标准储备液,4 ℃低温避光保存。精密吸取莫匹罗星的标准储备液1 ml,置于10 ml量瓶中,加65%甲醇稀释至刻度,摇匀,即得。

    糠酸莫米松对照品溶液:取糠酸莫米松10 mg,精密称定,置100 ml量瓶中,加入适量65%甲醇,超声使其完全溶解,加65%甲醇稀释至刻度,摇匀,得到糠酸莫米松的标准储备液,4 ℃低温避光保存。精密吸取糠酸莫米松的标准储备液1 ml,置于10 ml量瓶中,加65%甲醇稀释至刻度,摇匀,即得。

    混合对照品溶液:取酮康唑、莫匹罗星和糠酸莫米松的标准储备液各1 ml,置10 ml量瓶中,加65%甲醇稀释至刻度,摇匀,即得。

  • 取复方酮康唑软膏0.5 g,精密称定,置于50 ml的容量瓶中,加65%甲醇适量,超声溶解,加65%甲醇稀释至刻度,摇匀,即得供试品溶液。

  • 取空白软膏基质0.5 g,精密称定,置于50 ml的容量瓶中,加65%甲醇适量,超声溶解,加65%甲醇稀释至刻度,摇匀,即得阴性对照溶液。

  • 取上述对照品溶液、供试品溶液和阴性对照溶液,用0.22 μm微孔滤膜过滤,弃去初滤液,续滤液分别按照上述色谱条件进样,记录色谱图及相关参数。莫匹罗星的保留时间为5.075 min,理论塔板数为9196,对称因子0.81;糠酸莫米松的保留时间为18.413 min,理论塔板数为11859,对称因子0.88;酮康唑的保留时间为23.318 min,理论塔板数为12291,对称因子0.89,空白基质对莫匹罗星、糠酸莫米松和酮康唑的测定无干扰,方法专属性好。对照品溶液、供试品溶液及阴性对照溶液色谱见图2

  • 分别精密吸取酮康唑、莫匹罗星和糠酸莫米松标准储备液各0.2、0.4、0.8、1.0、1.2、1.4、1.6、2 ml,置10 ml量瓶中,用65%甲醇稀释至刻度,摇匀,0.22 μm微孔滤膜过滤,弃去初滤液,续滤液按上述色谱条件分别进样10 µl,记录色谱图峰面积。以峰面积A对浓度C (µg/ml)进行线性回归,结果见表1

  • 本研究根据软膏剂的特性,选择了提取效率较高,操作简便的超声提取法进行样品前处理,对溶剂种类、溶剂体积、提取时间进行考察,最终选择65%甲醇50 ml,超声提取10 min,该提取方法可有效的除去样品中的杂质,让测定的专属性更高。

  • 对于流动相的选择,本实验尝试以甲醇-0.6%醋酸铵溶液作为流动相[9-12],结果基线非常不稳定,这可能是由于醋酸铵的紫外吸收所造成。以甲醇-水、乙腈-水,甲醇-磷酸二氢钠溶液和甲醇-乙腈-水等作为流动相[13-15],使用磷酸二氢钠溶液分离效果及峰形较好,有机相甲醇的比例应控制在一定范围,甲醇低于50%则酮康唑峰保留时间过长;流动相的酸度对酮康唑(弱碱性)和莫匹罗星(弱酸性)[16]的峰形及保留时间亦有影响,用磷酸将磷酸二氢钠的pH值调节到4.5、5.0、5.5和6.0。结果表明,当流动相的pH值为5.5时,莫匹罗星、糠酸莫米松和酮康唑的三组峰值均具有较好的分离度,并且无前延和拖尾现象。对于检测波长的选择,酮康唑、莫匹罗星和糠酸莫米松在220 nm与248 nm均有吸收,因在供试品中酮康唑和莫匹罗星的浓度均是糠酸莫米松的20倍,为了让这三种药物能同时测定,提高检测的灵敏度,确定最佳检测波长为248 nm。对于色谱柱的选择,本研究考察了岛津、安捷伦和沃特世等品牌的色谱柱,最终选择了岛津Intersil ODS-3柱,三种待测成分在该柱上分离度好,峰形佳,所以确定为最佳色谱柱。

  • 3个批次的复方酮康唑软膏均为实验室自制,从测定结果可以看出,不同批次的样品中酮康唑、莫匹罗星和糠酸莫米松的含量有一定波动,这提示我们在进行中试放大生产时,要充分考虑各因素的影响,保证制剂中主要成分的含量稳定,同时对软膏剂的长期稳定性也需要进行考察。
