本发明涉及一种口腔速溶膜及其制备方法,所述口腔速溶膜,其中各组分的重量百分比如下:
Description
技术领域
本发明属于药物制剂范畴,涉及一种口腔速溶膜及其制备方法,特别涉及植物可溶性多糖作为膜剂辅料增加溶解时间的应用。
背景技术
口腔速溶膜又称为口溶膜剂、口腔溶解膜剂、口腔分散膜剂,是一种新型药物传递系统,是指局部或系统的在口腔中或通过胃肠道吸收提供治疗的含药聚合物薄膜。口溶膜剂由药物和成膜材料组成,其大小、形状、厚度类似于邮票,适用于儿童、老年、吞咽困难等患者药物和适宜的成膜材料经过加工制成膜状制剂,供口服使用的一种药物剂型。无需喝水即可在唾液中能快速溶解、释放药物。
桔梗是一种常用中药材。具有宣肺、祛痰、利咽、排脓等功能,主治咳嗽痰多、咽喉肿痛等症状。桔梗多糖是从桔梗中提取的多糖,提取方法属于现有技术,如文献“桔梗多糖提取方法的比较”中公开了热水浸提法,超声提取法,微波提取法。中国专利2014106285207中的提取方法如下:选择晒干的桔梗,粉碎后过40-80目筛,得桔梗粉,在桔梗粉中加水并搅拌均匀,桔梗粉与水的重量比例为1:5-10,在水中浸泡8-16小时,再加入纤维素酶,纤维素酶的添加量为0.5-0.9%、酶解温度45℃、pH值5,将上述的原料置于微波提取设备中提取,微波的功率为400-600W,频率为800MHZ,酶解0.1-0.5h;再加入无花果蛋白酶和菠萝蛋白酶,酶解温度45℃、pH值5.5-6.5,将上述的原料置于微波提取设备中提取得酶解液;将上述的酶解液置于真空浓缩器中浓缩,减压低温浓缩至酶解液至原体积的1/3,得桔梗粗多糖浓缩液;浓缩液按1:4比例加入95%乙醇沉淀静置10-30小时、离心10-30min,离心转速为4500rpm,收集沉淀并用乙醇反复清洗3-3次,冷冻干燥至水分含量为4-6%后,再在-1-4℃下进行粉碎,得可溶性多糖;
中药药渣来源于中成药生产、原料药生产、中药材加工与炮制、以及含中药的轻化工产品生产等。中药残渣在《工业固体废物名录》中属第15类废物。根据《麻醉药品和精神药品管理条例》(国务院令第442号)以及《麻醉药品和精神药品生产管理办法(试行)》(国食药监安〔2005〕528号)第二十三条规定:生产中产生的具有活性成分的残渣残液,由企业自行销毁并作记录。给生产厂家、社会、环境带来急需解决的难题,即药渣处理问题。
采用桔梗提取后的药渣制备桔梗多糖目前尚未文献报道,本发明为此进行了研究,得到一种从桔梗药渣中获得桔梗多糖的方法,所述方法,步骤如下:
桔梗水提后的残渣100g,加入1000ml碱水(2%NaOH溶液),煎煮4小时,后静置过夜,分离出上清液,量取滤液100ml,用稀盐酸中和,调节pH至中性,抽滤。将滤液倒入150ml烧杯中,加入适量活性炭粉末,搅拌1.5h后,抽滤即可,所得产物90ml,经鉴定为桔梗多糖。
本发明人对所得多糖进行研究,意外发现,其可以用于口溶膜制剂的制备与生产。将其作为润湿剂,添加到口溶膜剂中,得到的口腔膜剂具有适口性好、溶解速度快、载药量大、口腔粘附性良好的特点。
为此,本发明人在口溶膜剂研究中将有关的植物来源的可溶性多糖作为辅料,加入到难溶性药物制备的口溶膜剂中,可以使药物均匀分布,且大幅度缩短膜剂的溶解时间。
本发明提供的口溶膜剂,服用方便,药物释放迅速,可以令药物作用迅速。本发明示例之中,优选的药物包括,西地那非,酒石酸唑吡坦,其中所述酒石酸唑吡坦适用于偶发性失眠症、暂时性失眠症;他达拉非适用于治疗前列腺良性增生的下尿路症状。
