Description

一种宠物用复方氯硝柳胺驱虫片剂及其制备方法
技术领域
本发明涉及一种宠物用复方氯硝柳胺驱虫片剂及其制备方法。
背景技术
兽医寄生虫病学的第一需要是开发出新的抗寄生虫药物。但新药开发需要耗费巨资,每个新药从着手研究到最后的注册、上市要经历很长时间。在原有药物的基础上,开发各种制剂剂型,利用现有药物和新技术制备出复方制剂是研制新药的一个研究方向。临床研究结果证明,复方制剂与单剂药有同样的高疗效、药物不良反应少,服用方便等优点,在日常的防治工作中,更易避免漏服,保障用药的合理性。宠物由于其自身特点,不会像人那样利用自己的理智去服药,因此合适的剂型显得尤为重要。片剂是公认的较适合宠物的口服制剂。在我国,氯硝柳胺与盐酸左旋咪唑均是中国兽药典2005版收载的品种,其单方制剂已能大批量生产,复方制剂尚未见报道及销售。
发明内容
本发明的目的在于提供一种工艺可行、投服方便、驱虫效果好的宠物用复方氯硝柳胺驱虫片剂及其制备方法,它能满足当前日益复杂的宠物体内寄生虫感染及越来越严重的抗药性对新兽药的需求。
一种宠物用复方氯硝柳胺驱虫片剂,其特征在于它的组分及质量百分数分别为氯硝柳胺68~80、盐酸左旋咪唑3~5、淀粉13~20、用于制备乙醇水溶液的聚乙二醇40000.1~1、羧甲基淀粉钠3~6、硬脂酸镁0.5~1。
上述宠物用复方氯硝柳胺驱虫片剂的制备方法,其特征在于称取氯硝柳胺,加入淀粉混合粉碎过60~100目筛,制得均匀混合物;另将盐酸左旋咪唑溶于乙醇水溶液中,该乙醇水溶液中溶有质量百分浓度为5%~15%的聚乙二醇4000,再将该乙醇水溶液加入上述混合物中,制成软材,用14~20目筛制粒,50℃~70℃下干燥,所得干颗粒用14~20目筛整粒,加入硬脂酸镁及羧甲基淀粉钠,混合均匀,压片,即得产品。
本发明的片剂外观光洁,崩解迅速,片剂各项指标均达到了最优化,口服后驱虫效果好,且工艺简单、可行、成本低,适合工业生产。
具体实施方式
本发明的组分及质量百分数分别为氯硝柳胺68~80、盐酸左旋咪唑3~5、淀粉13~20、用于制备乙醇水溶液的聚乙二醇4000 0.1~1、羧甲基淀粉钠3~6、硬脂酸镁0.5~1。制备时称取氯硝柳胺,加入淀粉混合粉碎过60~100目筛,制得均匀混合物;另将盐酸左旋咪唑溶于乙醇水溶液中,该乙醇水溶液中溶有质量百分浓度为5%~15%的聚乙二醇4000,再将该乙醇水溶液加入上述混合物中,制成软材,用14~20目筛制粒,50℃~70℃下干燥,所得干颗粒用14~20目筛整粒,加入硬脂酸镁及羧甲基淀粉钠,混合均匀,压片,即得产品。
本发明采用硬脂酸镁为润滑剂,羧甲基淀粉钠为崩解剂,以5%~15%的聚乙二醇4000乙醇水溶液为黏合剂。所述的乙醇水溶液中乙醇的质量百分数范围为48%~52%。本发明以氯硝柳胺为主药,以盐酸左旋咪唑为辅药,盐酸左旋咪唑主治线虫,氯硝柳胺对绦虫及前后盘吸虫均有很好的疗效,二药无配伍禁忌,组成的复方抗虫谱广、成本低、临床效果好。
本发明以淀粉为稀释剂,同时兼有帮助主药氯硝柳胺粉碎过筛的作用。氯硝柳胺粉碎过筛时,先加入淀粉混合制得混合物,过60~100目筛,从而克服了因主药静电作用而自行聚集成团,不易过筛,难以混合均匀的缺点。
本发明将处方量的盐酸左旋咪唑溶于5%~15%的聚乙二醇4000乙醇水溶液中,再将它们加入上述混合物中制软材,从而避免了辅药太少而导致的片剂均匀度不合格问题。
实施例
取氯硝柳胺750g,加入淀粉150g混合粉碎,过100目筛,制得均匀混合物;另将盐酸左旋咪唑37.5g溶于20g质量百分浓度为10%的聚乙二醇4000的乙醇水溶液,其中乙醇和水的质量百分数均为50%;再将后者加入上述混合物中,制成软材,用20目筛制粒,50℃~70℃下干燥,所得干颗粒用20目筛整粒,整粒后加入5.5g硬脂酸镁及55g羧甲基淀粉钠,混合均匀,压片,使制得片剂光洁美观,片重控制在245mg~280mg。
