Description
技术领域
本发明涉及一种三唑类抗真菌药,尤其涉及泊沙康唑干混悬剂及其制备方法。
背景技术
泊沙康唑是一种新型三唑类抗真菌药,通过抑制真菌细胞色素P450 14α-去甲基化酶造成14α-去甲基甾醇等的累积,抑制角麦甾醇的合成,从而发挥抗真菌的作用。泊沙康唑具有广谱抗菌活性,主要用于难治性疾病或其他药物耐药引起的真菌感染,如曲霉病、镰刀菌病和接合菌病。泊沙康唑的溶解性受PH影响较大,在胃酸性环境中溶解度较高,但在中性或碱性肠道环境中溶解度很小,而肠道则是药物吸收的主要部位,这是泊沙康唑口服制剂生物利用度低且个体差异大的主要原因。因此,增加泊沙康唑在肠道中的溶解度就显得非常重要。
发明内容
本发明的目的在于提供一种肠道内溶解度高、生物利用度高的泊沙康唑干混悬剂;
本发明的另一目的在于提供一种泊沙康唑干混悬剂的制备方法。
为了实现上述发明目的,本发明采用如下技术方案:
泊沙康唑干混悬剂,包括如下重量比的组分:泊沙康唑3%~10%、稀释剂75%~90%、粘合剂1%~5%、助悬剂0.1%~1%、二氧化硅3%~20%、助流剂0.1%~1%,泊沙康唑与二氧化硅的重量比为1:0.5~2。
所述的泊沙康唑与二氧化硅的重量比为1:1。
所述的泊沙康唑与二氧化硅的重量比为1:2。
所述的稀释剂是甘露醇。
本发明还公开了泊沙康唑干混悬剂的制备方法,包括如下步骤:
(1)API-二氧化硅颗粒制备:将PEG400介质加热至100℃,加入泊沙康唑原料和二氧化硅颗粒以及部分粘合剂,进行高速均质,使二氧化硅沉积于药物表面,然后过滤,干燥至水分低于2.0%;
(2)预混合:将上述API-二氧化硅颗粒、稀释剂和剩余粘合剂于高剪切湿法制粒机中预混5min;
(3)湿法制粒;
(4)湿整粒;
(5)干燥;
(6)干整粒;
(7)混合:将干整粒颗粒、助悬剂、助流剂置于混合桶内混合均匀后灌装即得。
本发明泊沙康唑干混悬剂采用均质分散沉积法,在PEG400介质中加入二氧化硅进行高速均质,使二氧化硅沉积在药物表面,利用二氧化硅的亲水性增加药物的亲水性,提高溶解度,进而提高药物溶出速率和生物利用度。
具体实施方式
实施例1:采用二氧化硅沉积法(泊沙康唑:二氧化硅1:0.5)
采用如下物料:
制备过程:
(1)API-二氧化硅颗粒的制备:将PEG400介质加热到100℃,加入泊沙康唑原料、一部分聚维酮、二氧化硅进行高速均质分散,使二氧化硅沉积在药物表面;然后过滤,干燥至水分低于2.0%;
(2)预混合:将上述API-二氧化硅颗粒、甘露醇、剩余的聚维酮置于高剪切湿法制粒机中预混5min;
(3)湿法制粒:喷雾的形式加入适量的纯化水进行制粒;
(4)湿整粒:将湿颗粒过4*4mm孔径的筛网进行湿整粒;
(5)干燥:将上述颗粒置于流化床内进行干燥,干燥温度为60℃,干燥至水分低于2.0%时,结束干燥;
(6)干整粒:将干燥后颗粒过1.2mm筛网进行干整粒;
(7)混合:将干整粒颗粒、黄原胶、二氧化钛置于混合桶内混合均匀;
(8)灌装:将总混颗粒用复合膜袋进行分装,每份3000.0mg;
实施例2:采用二氧化硅沉积法(泊沙康唑:二氧化硅1:1)
采用如下物料:
制备过程与实施例1相同。
实施例3:采用二氧化硅沉积法(泊沙康唑:二氧化硅=1:2)采用如下物料:
制备过程与实施例1相同。
实施例4:无二氧化硅沉积
采用如下物料:
制备过程:
(1)预混合:将微粉化的泊沙康唑、甘露醇、聚维酮置于高剪切湿法制粒机中预混5min;
(2)湿法制粒:喷雾的形式加入适量的纯化水进行制粒;
(3)湿整粒:将湿颗粒过4*4mm孔径的筛网进行湿整粒;
(4)干燥:将上述颗粒置于流化床内进行干燥,干燥温度为60℃,干燥至水分低于2.0%时,结束干燥;
(5)干整粒:将干燥后颗粒过1.2mm筛网进行干整粒;
(6)混合:将干整粒颗粒、黄原胶、二氧化钛置于混合桶内混合均匀;
(7)灌装:将总混颗粒用复合膜袋进行分装,每份3000.0mg;
实施例5:质量评价
1、测定实施例1~实施例4的溶出:
溶出方法:桨法、50rpm、0.3%十二烷基硫酸钠水溶液、900ml;
溶出结果:
由上表可知,实施例4中没有采用二氧化硅沉积,其15分钟内的溶出较少;泊沙康唑的溶解性在PH小于3的条件下较好,因此需要在胃酸环境下溶出,而一般药物在胃内的滞留时间较短,需要在短时间内溶出效果越好则药物的生物利用度越高。而采用了二氧化硅沉积法制备得到的泊沙康唑干混悬剂,15分钟的溶出达到90%以上,明显提高溶出效果从而提高药物的生物利用度。
2、沉降体积比
按照《中国药典》2015版第二部附录口服混悬剂的要求,检查沉降体积比:取供试品5袋,倒出内容物,加入50ml具塞量筒内,加入48ml水,强力振摇后,初始高度为50ml(H0),静置1、5、12、24小时记录溶液的高度H,H/H0应不低于0.9,即符合规定,具体数据如下:
3、加速稳定性
由加速稳定性实验结果可知,采用了二氧化硅沉积法获得的泊沙康唑干混悬剂稳定性数据合格,加速6个月后溶出度无显著变化。
