Description
技术领域
本发明涉及一种含有氢溴酸伏硫西汀的薄膜包衣片及其制备方法,属于药物制剂技术领域。
背景技术
抑郁症是一种常见的精神疾病,全球累计患病人数超过3.5亿。世界卫生组织在2012年发布的一份题为《抑郁症:全球性危机》的报告中指出,抑郁症已成为中国负担第二大的疾病。中国的患病率为3.02%,有超过4000万人患有抑郁症。但是,相对于高血压、糖尿病等慢性疾病,抑郁症存在着就诊率低的现象。
伏硫西汀(Vortioxetine)是一种新型抗抑郁药物,由丹麦灵北制药公司(Lundbeck)和日本武田药品公司(Takeda Pharmaceutical)研发,化学名为:1-[2-(2,4-二甲基苯基硫烷基)-苯基]哌嗪。2013年该药获得美国食品药品管理局(FDA)的上市批准,商品名为心达悦。该药为5-HT3、5-HT7、5-HT1D受体拮抗剂、5-HT1B受体部分激动剂、5-HT1A受体激动剂、5-HT转运体抑制剂,通过调节5-HT起到抗抑郁作用,用于治疗成人重性抑郁障碍。多项临床研究表明,伏硫西汀对于治疗成人重度抑郁症(MDD)有较好的疗效,且安全性和耐受性良好。
伏硫西汀口服给药后吸收缓慢但吸收良好,在7至11小时内达到最大血浆浓度。按5mg、10mg、20mg每天的剂量给药后,观察到的稳态平均CMAX为9~33ng/ml,未发现食物对药代动力学的影响。
目前,该药已获得国家食品药品监督管理总局(CFDA)的上市批准,规格为5mg和10mg,国内暂时没有仿制药上市。根据中国专利CN200780022338.5报道,该片剂采用湿法制粒工艺制备。但湿法制粒工艺所得颗粒细粉较多,影响可压性,使用乙醇等有机润湿剂易产生有机残留。本发明采用干法制粒工艺,颗粒粒径分布稳定可控,所制颗粒用于压片可压性良好,且制备过程中不引入水分及有机试剂。
发明内容
本发明提供了一种氢溴酸伏硫西汀薄膜包衣片及其制备方法。该方法采用干法制粒,加入填充剂、崩解剂、粘合剂、润滑剂等赋形剂制成片剂,不引入额外水分及有机试剂,操作简单,工艺稳定且可控,易于掌握。
本发明提供一种含氢溴酸伏硫西汀的薄膜包衣片及其制备方法,包括:
(1)将有效量的氢溴酸伏硫西汀、填充剂、崩解剂、粘合剂粉碎过筛后,得到合适的粒径分布的颗粒;
(2)将步骤(1)得到的颗粒混合均匀,得到混合物;
(3)将步骤(2)所得到的颗粒加入填充剂、崩解剂、润滑剂中的至少一种,混合均匀;
(4)将上述混合颗粒压片,用薄膜包衣预混剂进行包衣,得到氢溴酸伏硫西汀薄膜包衣片。
优选的,所述步骤(3)中颗粒粒径分布满足60目以上颗粒占30%~80%;
优选的,颗粒的粒径分布满足60目以上颗粒占30%~70%;更优选的,颗粒的粒径分布满足60目以上颗粒占30%~50%;
优选的,步骤(1)所述的填充剂选自甘露醇、微晶纤维素、乳糖、磷酸氢钙、预胶化淀粉、玉米淀粉中的一种或几种;
优选的,步骤(1)所述的崩解剂选自羧甲基淀粉钠、交联聚维酮、交联羧甲基纤维素钠、低取代羟丙基纤维素中的一种或几种;
优选的,步骤(1)所述的粘合剂选自羟丙基纤维素、聚维酮、羟丙甲纤维素、乙基纤维素中的一种;
优选的,步骤(4)所述的润滑剂选自硬脂酸镁、山嵛酸甘油酯、硬脂富马酸钠中的一种或几种;
优选的,步骤(5)所述的薄膜包衣预混剂为欧巴代薄膜包衣预混剂;
所述活性成分氢溴酸伏硫西汀的含量为5mg/片~10mg/片。
有益效果
与现有制备方法相比,该发明无需另加润湿剂,工序较少,无有机残留及易爆等危险。混制备工艺简单,且干法制粒机参数设定后无需其他操作,相比湿法制粒,所得颗粒质量更加均一稳定,更加适合规模化生产。

实施例5
制备工艺
(1)将氢溴酸伏硫西汀、甘露醇、羟丙纤维素、交联羧甲基纤维素钠、硬脂酸镁分别过60目筛一次备用;
(2)将氢溴酸伏硫西汀、甘露醇、微晶纤维素、羟丙纤维素、交联羧甲基纤维素钠加入三维混合机混合均匀;
(3)将(2)中混合物加入干法制粒机制粒,制粒筛网选用16目,60目以下细粉再次制粒,至颗粒粒径分布满足60目以上颗粒占30%~50%;
(4)干法制粒所得颗粒,加入交联羧甲基纤维素钠、硬脂酸镁,三维混合机中混合均匀;
(5)杏仁形异形冲压片,硬度6kg~10kg,控制片重,欧巴代薄膜包衣预混剂以水为分散体系分散均匀,采用高效包衣机包衣,包衣增重4%,即得氢溴酸伏硫西汀薄膜包衣片。实施例1、2、3分别通过干法制粒制备了不同颗粒率范围的样品,实施例4通过湿法制粒工艺制备,实施例5改变了赋形剂的加入方式。将上述实施例与心达悦片剂(10mg)进行溶出曲线对比,计算F2因子,并且在光照、40℃、60℃、RH75%、RH92.5%条件下放置影响因素,比较稳定性的差异。
溶出曲线测定方法:使用富科思12杯溶出仪,根据2015版中国药典四部特性检查法下溶出度与释放度测定法二法,介质体积为900ml,温度为37℃,转速为50rpm,实施例溶出结果如下:
影响因素结果如下:
本发明实施例1、2、3、5与心达悦片剂溶出曲线比较,F2均大于50,溶出相似,实施例1~3颗粒率依次增大,溶出速率依次减慢,实施例1与心达悦片剂的F2因子最大,相似性最高。因此颗粒率可选30%~80%,优选为30%~70%,更优选的为30%~50%。将部分崩解剂外加,F2因子仍大于50,因此该制备工艺亦可行。相同处方分别采用湿法制粒和干法制粒制备,干法制粒的处方总杂更小,在影响因素条件下,有关物质也小于湿法制粒处方,因此本发明减少了制备过程中与水的接触,具有优越性。
以上仅是本发明的优选实施方式,并不用以限制本发明,对于本领域技术人员来说,在不脱离本发明原理的前提下,还可以做出的若干改进、润饰、等同替换,均应包含在本发明保护范围之内。
