Description

一种β-葡聚糖作为粘合剂在制备片剂或颗粒剂中的应用 技术领域:
本发明涉及药物制剂领域,涉及β-葡聚糖作为粘合剂在制备片剂中的应用,具体涉及一种β-葡聚糖片剂及其制备方法。
背景技术:
燕麦中的β-(1→3,1→4)葡聚糖简称燕麦β-葡聚糖,是一种相对分子质量较小的短链葡聚糖,相对分子质量的变化范围为5300-257200,存在于燕麦胚乳和糊粉层细胞壁中。其组成单体为β-D-吡喃葡萄糖,连接类型为β-(1→3)和β-(1→4)糖苷键.
燕麦β-葡聚糖具有多种治疗效果,如抗肿瘤、抗氧化应激、抗组织纤维化、防治病毒感染、防治致病菌感染、防治神经退行性疾病、降低发生心肌梗死或脑卒中或心血管疾病导致的风险、改善心肌缺血和改善脑缺血、保护心脑细胞、降血脂、防治心脑血管疾病等。
燕麦β-葡聚糖作为一种天然提取物,副作用小,是一种非常有潜力药物,但其理化性质上却存在相当的问题,使得现有技术中很少将其制备成药物制剂形式:
(1)燕麦β-葡聚糖易吸湿,遇水后易结块,具有一定的粘性。目前燕麦β-葡聚糖通常采用用水冲饮,直接送服的方式,这种方式使得部分活性成分无法充分得到溶胀,无法发挥药物的最大功效,进入体内后也无法充分吸收。
(2)燕麦β-葡聚糖分散性较差,导致其与其他辅料混合不均匀,可压缩性差,再后续制备颗粒或压片的过程中存在含量不均一的问题。
因此,有待研究上述问题,得到一种燕麦β-葡聚糖的药物制剂,提高燕麦β-葡聚糖的分散性和生物利用度,以满足临床的需要,具有很好的市场前景。

优选的,所述药物组合物的剂型为片剂或胶囊。
本发明的另一目的是提供了一种β-葡聚糖药物组合物的制备方法:将β-葡聚糖和表面活性剂十二烷基硫酸钠共同分散在有机溶剂中,充分搅拌后干燥,进一步气流粉碎,得到β-葡聚糖-十二烷基硫酸钠改性粉末,将该粉末与其他辅料混合后制备得到药物制剂。
本发明具体制备方法如下:

(2)利用燕麦β-葡聚糖自身粘性制粒,无需添加粘合剂,处方组成简单,既能保证片剂的成型,又能保证片剂或胶囊剂的溶出速度。
(3)制备燕麦β-葡聚糖与表面活性剂十二烷基硫酸钠的改性粉末,有效提高了燕麦β-葡聚糖的分散性,提高制剂的均匀性和一致性,增强制剂的溶出效果。

对比例1-3(粘合剂的使用):
Figure PCTCN2020123828-appb-000004
除了制粒方法有区别外,其余制备方法同实施例1。其中,采用湿法制粒制备得到 的片剂可压性差,且压片过程中出现黏冲现象,主要原因是β-葡聚糖易吸湿,在湿法制粒过程中粘度增大,导致黏冲。由于β-葡聚糖自身具有粘性,可以在片剂成型过程中发挥很好的粘合剂作用,无需添加其他粘合剂。
对比例4:
处方组成均与实施例1处方1一致,区别仅在于制备方法为:将所有辅料混合后,直接压片。该方法制备得到的片剂可压性差,不能成型,成型的片剂脆碎度低。其原因主要是β-葡聚糖的分散性差和可压性差,与辅料直接混合混合不均匀,导致片剂成型困难。
对比例5:
处方组成均与实施例1处方1一致,区别在于制备方法为:将β-葡聚糖与十二烷基硫酸钠直接混合,气流粉碎,得到β-葡聚糖-十二烷基硫酸钠混合粉末,与乳糖,微晶纤维素,交联羧甲基纤维素钠混合后干法制粒。
实验例1燕麦β-葡聚糖标准曲线的绘制
采用刚果红分光光度法测定燕麦β-葡聚糖浓度,具体方法如下:
(1)燕麦β-葡聚糖标准溶液的配制:准确称取20mg燕麦β-葡聚糖,加少量去离子水,在70℃水浴条件下搅拌溶解,待其溶解完全后,取出冷却至20℃,加去离子水定容至200mL,得标准溶液(0.1mg/mL)。
(2)刚果红溶液的配置:准确称取刚果红试剂0.020g,用磷酸缓冲液(0.1mol/L、pH8.0)溶解并定容至200mL。
(3)标准曲线的绘制:取10mL试管6只,分别加入0、0.2、0.4、0.6、0.8、1.0mL燕麦β-葡聚糖标准储备液(0.1mg/mL),用去离子水补至1.0mL,然后各加入4.0mL刚果红溶液(0.1mg/mL),摇匀,于20℃的水浴中静置30min,在545nm波长条件下测定吸光度值,以燕麦β-葡聚糖的质量浓度为横坐标,吸光度值为纵坐标,绘制标准曲线。
实验例2溶出度测定
对各实施例和比例得到的燕麦β-葡聚糖片进行含量均一性和溶出试验,本发明所采用的溶出度测定方法如下:参照《中国药典2015年版四部通则》0931第二法溶出度测定法,以磷酸盐缓冲液(pH值至7.4)900ml为溶出介质,转速为每分钟75转,依法操作,分别于10、30、45、60、90、120分钟各取样5mL,同时补加5mL同等温度的新鲜溶出介质。样品经0.22μm滤膜过滤后,采用刚果红法测量并计算累计溶出百分率,结果见下表:
表1本申请实施例1-9片剂的溶出量考察
Figure PCTCN2020123828-appb-000005
由溶出度实验可以看出,本发明实施例1-9的片剂,均能达到很好的溶出效果,而在片剂中添加普通的粘合剂(对比例1)后,以及未经溶解于有机溶剂分散(对比例4),片剂溶出均很低,原因如下:(1)由于β-葡聚糖自身具有一定的粘性,可以在片剂成型过程中发挥一定的粘合作用,又能保证药物的溶出。而添加了本领域常用的粘合剂的片剂(对比例1),溶出度下降,粘合剂的存在不利于β-葡聚糖的溶出。(2)β-葡聚糖溶解度差,分散性差,仅采用常规气流粉碎的方式并不能很好的改善药物的溶出,而本发明采用了先将药物与表面活性剂分散在有机溶剂中预处理的方式,再进行气流粉碎,很好的改善了药物的溶出度,进而提高药物的生物利用度。
以上所述仅为本发明的优选实施例,并不用于限制本发明,对本领域技术人员来说,本发明可以有各种更改和变化,凡在本发明的精神和原则之内,所作的任何修改、等同替换、改进等,均应包含在本发明的保护范围内。
