Description
技术领域
本发明涉及药物制剂技术领域,尤其涉及一种盐酸阿比多尔缓释胶囊及其制备方法。
背景技术
阿比多尔(又称“阿比朵尔”,Arbidol),其化学名称为:6-溴-4-(二甲氨基甲基)-5-羟基-1-甲基-2-(苯硫甲基)-1H-吲哚-3-羧酸乙酯盐酸盐。
目前,上市的阿比多尔剂型有胶囊、片剂、口服混悬剂多种剂型,由于药物中有效成份释放速度过快,使血药浓度波动较大,不能保证药物使用的有效性和安全性,且患者服药次数多,造成长期服药的慢性疾病患者使用不方便。同时阿比多尔水溶性较差,缓释制剂常存在最终释药不完全的现象。
发明内容
针对盐酸阿比多尔药物释放不稳定、不完全的问题,本发明提供一种药物平稳释放、生物利用度高的盐酸阿比多尔缓释胶囊。
为达到上述发明目的,本发明实施例采用了如下的技术方案:
一种盐酸阿比多尔缓释胶囊,该缓释胶囊的内容物为缓释微丸,该缓释微丸由作为母核的空白丸芯及依次包裹在所述空白丸芯外的隔离层、含阿比多尔的主药层和缓释包衣层组成;所述隔离层的成分包括粘合剂和滑石粉,所述主药层的成分包括盐酸阿比多尔、粘合剂、水溶性填充剂和聚乙二醇400,所述缓释包衣层的成分包括粘合剂和致孔剂;所述粘合剂包括乙基纤维素、羟丙甲纤维素和Eudragit S100;所述缓释微丸各部分按重量份数计分别为:空白丸芯10~20份,隔离层5~15份,含药层25~50份,缓释包衣层15~30份。
本发明采用乙基纤维素、羟丙甲纤维素和Eudragit S100复合作为粘合剂,并将该特定的粘合剂既用于主药层又用于缓释包衣层,使阿比多尔层层包封于该缓释材料内,以调节阿比多尔释放速率,确保阿比多尔平稳释放;滑石粉在本发明具有控释溶出的功效,能够协同粘合剂起到隔离的作用,使丸芯不能释放,降低了缓释微丸内部的渗透压,减缓了药物的释放速度;水溶性填充剂可在水中溶解形成释药通道,本发明通过采用特定的水溶性填充剂与粘合剂的比例可以有效防止药物发生突释现象,同时协同聚乙二醇400,能够提高阿比多尔在释放初期的溶出度,使其部分有效释放,确保患者在服药初期即达到有效的血药浓度,但同时还确保阿比多尔不会释放速度过快而削弱缓释效果。
本发明通过该微丸结构以及各层中不同成分的协同,使制备的盐酸阿比多尔缓释胶囊能在初期释放部分阿比多尔,较快地提升血药浓度至有效阈值,之后有效控制阿比多尔的释放速度,实现12小时内平稳而缓慢地释放,避免血药浓度产生大幅度波动,同时又能使阿比多尔在12小时内释放完全,从而提高了阿比多尔的用药安全性和有效性,能够减少给药次数,提高患者服药依从性。
优选地,缓释微丸按照以下重量份数组成:空白丸芯15份,隔离层10份,含药层40份和缓释包衣层25份。
更优选的重量份数制得的缓释微丸配比更合理,能够使阿比多尔具有更平稳的释放速率和更多的累计释放量,保证药物的平稳释放和生物利用度。
优选地,所述隔离层中粘合剂和滑石粉的重量比为(2~4):1。
优选地,所述主药层中盐酸阿比多尔、粘合剂、水溶性填充剂和聚乙二醇400的重量比为(6~10):1:(1~1.5):(0.5~1),所述水溶性填充剂为蔗糖、甘露醇、果糖和乳糖中的一种或多种。
优选地,所述缓释包衣层中粘合剂和致孔剂的重量比为(5~10):1,所述致孔剂为聚维酮K30和K90中的一种或两种。
将上述致孔剂用于缓释包衣层,能够与粘合剂协同调节药物释放速率,并更好地提升阿比多尔的溶出效果。
通过上述隔离层、含药层和缓释包衣层中各组分的合理配比,能够使阿比多尔的释放速度得到有效控制,同时保证阿比多尔在一定时间内完全释放,从而能更好发挥盐酸阿比多尔的药效,提高其药物有效率,减少给药次数,提高患者服药依从性。
优选地,所述乙基纤维素、羟丙甲纤维素和Eudragit S100的重量比为6:(0.5~1):(1.5~2)。
乙基纤维素为pH依赖性的水不溶性缓释材料,不受胃肠道环境的影响,协同特定比例的羟丙甲纤维素和Eudragit S100能够保证药物在体内平稳释药。
以及,本发明实施例还提供一种盐酸阿比多尔缓释胶囊的制备方法,包括以下步骤:
步骤1:称取粘合剂的各组分,加入75%~95%的乙醇配制成10%~30%的粘合剂溶液待用,将空白丸芯放入离心造粒机中,喷液上粉,使处方量的粘合剂溶液和滑石粉包覆在空白丸芯上,制成具备隔离层的微丸;
步骤2:称取盐酸阿比多尔、水溶性填充剂和聚乙二醇400加入含有处方量粘合剂的粘合剂溶液中混合均匀,喷在步骤1制成的具备隔离层的微丸上,制成具备主药层的微丸;
步骤3:称取致孔剂加入含有处方量的粘合剂的粘合剂溶液搅拌均匀,喷在步骤2制成的具备主药层的微丸上,干燥,制成具备缓释包衣层的所述缓释微丸,选取25~45目的所述缓释微丸装入胶囊中,即得所述阿比多尔缓释胶囊。
本发明的盐酸阿比多尔缓释胶囊的制备方法,制备得到的微丸流动性好、圆整度高、收率高于80%,制备工艺简单,隔离层、含药层及缓释包衣层的制备过程均在离心造粒机中完成,并且各步骤中离心造粒机的工艺参数可以相同,无需在制备过程中调整参数,提高了生产效率,并且无需在制备过程中取出物料待参数稳定后重新加入,减少了人工操作,降低制备过程中的物料损失,节约成本。
优选地,喷洒时的工艺参数设置为造粒机转速为50~70rpm,各步骤的喷液速度为100~200g/min,雾化压力为0.3~0.4MPa,加粉速度为200~300g/min。
合适的喷液速度和加粉速度使粉末层积速度适中,制得微丸的圆整度较好;合适的转速使微丸的润滑性良好,保证微丸的收率,过快会使层积部分容易发生脱落,导致润湿性不好,收率下降。
优选地,阿比多尔缓释微丸的干燥温度为40~50℃,干燥时间为6~8小时。

2、溶出曲线测定:
对实施例1-3、对比例1-2进行溶出曲线测定,检测结果如表1~3所示。
表1溶出介质为0.1mol/L盐酸溶液的释放度结果
表2溶出介质为pH4.5醋酸盐缓冲液的释放度结果
表3溶出介质为水的释放度结果
影响因素试验:
为考察本发明实施例制备的盐酸阿比多尔缓释微丸的稳定性,按照中国药典2015年版四部通则《原料药与药物制剂稳定性试验指导原则》和ICH Q1A Q1B的要求,对实施例1制备得到的产品分别进行了高温、高湿的影响因素试验研究,试验条件如表4所示,试验结果如表5-表6所示。
表4
表5影响因素高温试验结果
