Description
技术领域
本发明涉及一种药物固体制剂,特别涉及一种盐酸西替利嗪口服溶液及其制备方法,属于药物制剂领域。
背景技术
盐酸西替利嗪为白色或类白色结晶性粉末;无臭、味苦,有引湿性,在水中易溶,在甲醇或乙醇中溶解,在氯仿或丙酮中几乎不溶,盐酸西替利嗪是人体内羟嗪的代谢产物,动物实验证明盐酸西替利嗪为选择性组胺H1受体拮抗剂,抑制组胺的传递作用,还可抑制参与变态反应的血管活性肽及P物质,减少炎症细胞的移动,有效的抑制皮肤变态反应,对变态反应发作时的嗜酸性细胞的活化与趋化有抑制作用;对变应原皮肤试验,鼻粘膜及支气管激发试验亦有明显的抑制作用。
盐酸西替利嗪临床用于季节性和常年性过敏鼻炎,鼻结膜炎,荨麻疹及由药品、食品和昆虫叮咬引起的过敏反应。目前国内上市的剂型包括片剂、胶囊剂、分散片、口腔崩解片、糖浆、口服溶液、滴剂等。
盐酸西替利嗪作为一种极为优良的抗组胺药物,在世界范围内得到了极为广泛的应用,对于很多吞咽困难的老年患者或儿童,口服溶液剂无疑具有更大的优势,但盐酸西替利嗪具有较强的苦味且易用降解,给口服制剂,特别是口服溶液剂的开发带来较大的困难。
专利号02130823.3的中国发明专利公开了一种含左西替利嗪的抗过敏药物溶液剂,在1000ml药物组合物溶液中包括左西替利嗪或其药学上可接受的盐0.5~20g,聚乙烯吡咯烷酮20~100g、泊洛沙姆5~50g、聚乙二醇40010~250g,该溶液剂虽然提高了制剂的稳定性,但是泊洛沙姆为非离子表面活性剂,有较大的起泡性。在制备过程或运输过程都会产生大量的气泡而影响溶液的形态。在患者服用时由于气泡的存在对患者使用时的定量也带来了差异,并且泊洛沙姆有异味,加入量多会直接影响溶液的气味,不利于口服。
申请号201410562636.5的发明专利申请公开了一种由盐酸西替利嗪糖浆、制剂中含有盐酸西替利嗪、谷氨酸钠、黄原胶、蔗糖、pH调节剂、矫味剂和水,虽然胶乳了掩味剂黄原胶和蔗糖等矫味剂,可有效的掩盖西替利嗪的苦涩味道,但制备工艺复杂,需进行灭菌等处理,不仅增加了生产成本,而且盐酸西替利嗪经过高温灭菌后的稳定性也会较差。
申请号201310375767.8的发明专利申请公开的由盐酸西替利嗪溶液,包括了盐酸西替利嗪、甘露醇、羟苯基纤维素,可以有效的掩盖活性成分的苦涩味道,可以提高口服溶液的稳定性,但制备工艺需要将纯化水加热至沸腾10~20分钟,而且还需要降温至45~55℃才能进行溶液的配制,不仅增加了生产成本,还增加了生产周期。
发明内容
本发明的目的是针对上述现有盐酸西替利嗪口服溶液剂存在的技术问题,提供一种盐酸西替利嗪口服溶液,本发明的盐酸西替利嗪口服溶液的口感好,可以提高患者的用药顺应性,而且稳定性高,防止盐酸西替利嗪的降解和聚集,减少杂质的增加,同时药物在体内的吸收好,提高了药物的生物利用度,而且制备工艺简单,不需进行加热或灭菌,采用常规的液体制备工艺进行生产,生产成本较低。
为实现本发明的目的,本发明一方面提供一种盐酸西替利嗪口服溶液,由盐酸西替利嗪、稳定剂同时兼具改善口感70%山梨醇溶液和甘油,改善口感的糖精钠,掩味剂香蕉香精,防腐剂羟苯甲酯和羟苯丙酯,防腐剂增溶剂丙二醇,溶液调节剂冰醋酸和醋酸钠组成包括盐酸西替利嗪、丙二醇、甘油、70%山梨醇溶液、羟苯甲酯、羟苯丙酯、糖精钠、香蕉香精、冰醋酸和醋酸钠。

综上所述,糖精钠采用0.01%-0.15%时的用时,甜味比较适宜。
实施例3丙二醇和甘油用量的筛选
1)将主药盐酸西替利嗪与其他辅料按照如表5的配比备料,其中,每个处方按1000ml配制10瓶。每瓶100ml。
表5处方1-9的原辅料配比组成表
2)将羟苯甲酯和羟苯丙酯加入丙二醇中,搅拌使其溶解完全;
3)称取适量纯化水,加入糖精钠和香蕉香精,搅拌溶解完全;

将按照表5的处方制备的口服溶液置于温度40±2℃,相对湿度75%±5的条件下,加速试验30天,考察口服溶液的性状、pH值、有关物质和含量,检测结果见表6和表7所示。
表60天检测数据
表7高温40℃30天检测数据
由表6、7的加速试验结果表明:
处方1、2、3中甘油加入量为100g,溶液在经过高温40℃30天条件后,溶液的杂质相比于0天的杂质数据增加较多,说明甘油加入量较少,没有起到较好的溶液稳定剂的效果,丙二醇加入量为20g时,羟苯甲酯和羟苯丙酯溶解速度较慢,说明丙二醇用量偏少,当加入量为50g和80g,丙二醇溶解较快。
处方4、5、6中甘油的加入量为200g,溶液在经过高温40℃30天条件后,溶液的杂质相比于0天的杂质数据增加较少,说明此时的甘油加入量已经起到溶液稳定剂的效果,丙二醇加入量为20g时,羟苯甲酯和羟苯丙酯溶解速度较慢,说明丙二醇用量偏少,当加入量为50g和80g,丙二醇溶解较快。
处方7、8、9中甘油的加入量为300g,溶液在经过高温40℃30天条件后,溶液的杂质相比于0天的杂质数据增加较少,说明此时的甘油加入量已经起到溶液稳定剂的效果,但是溶液因甘油加入量较多,导致过滤时间显著增加,而且溶液黏度较大,口感相较于处方1-6差,也不利于生产,丙二醇加入量为20g时,羟苯甲酯和羟苯丙酯溶解速度较慢,说明丙二醇用量偏少,当加入量为50g和80g,丙二醇溶解较快。
综上所述,甘油的加入量不宜过少也不宜过多,过少起不到稳定剂的作用,过多会影响溶液的口感,丙二醇不宜过少,会影响羟苯甲酯和羟苯丙酯的溶解时间,不利于生产。
