Description
技术领域
本发明涉及一种配制方法,尤其是一种黄芩苷液配制方法。
背景技术
黄芩甙(苷)为黄酮类化合物,目前尚无国家批准生产的黄芩甙(苷)液用于临床,而黄芩甙(苷)药理活性是多方面的,它在清除氨自由基,减轻组织缺血再灌注损伤,调节免疫功能,保肝利胆、抗感染、抗肿瘤等方面均有一定的作用,是多种中药注射液、胶囊、饮片的组成成分,黄芩甙(苷)溶解度好,毒性小,具有潜在开发应用价值。
发明内容
本发明要解决上述所述的不足,提供一种黄芩苷液配制方法。
本发明解决其技术问题所采用的技术方案。这种黄芩苷液配制方法,1)、称取黄芩苷粉及抗氧化剂,其中黄芩苷粉按所需体积及设定的浓度称取,抗氧化剂为每100ml加0.1g,然后添加注射用水至预配量体积的75-85%;2)、用5%-10%碱性溶液和5%-10%酸性溶液以滴加或喷洒方式调节PH至6.5~8.5,按设定的浓度加水定容并静置3-12小时,即100毫升含设定值的黄芩苷,测渗透压合格;3)、添加活性炭,按照每100ml液体加0.1-0.2g,在80℃条件下保温半小时,放置冷却3天~1周后,依次用滤纸、垂熔漏斗、0.22um微孔滤膜过滤,分装于玻璃容器内,115℃灭菌30分种,灯检提示澄明,静置无沉淀,并经动物实验证实其溶血、热原、血管脆性、无菌试验合格后即得。
本发明所提供的黄芩苷液配制方法还可以进行完善。所述的抗氧化剂为无水亚硫酸钠、硫代硫酸钠或其它抗氧化剂。所述的碱性溶液为NaOH、碳酸氢钠、磷酸二氢钠、磷酸氢二钠或其他碱性溶液。所述的酸性溶液为盐酸或磷酸或其他酸性溶液。
在步骤2中可以加入1%-5%的亲脂性助溶剂,所述的亲脂性助溶剂为聚乙二醇,以增加其稳定性。还可以在步骤2和步骤3之间添加精品氯化钠或精品葡萄糖粉,调渗透压到等渗状态。
本发明有益的效果是:黄芩甙(苷)药理活性是多方面的,它在清除氨自由基,减轻组织缺血再灌注损伤,调节免疫功能,保肝利胆、抗感染、抗肿瘤等方面均有一定的作用,是多种中药注射液、胶囊、饮片的组成成分,黄芩甙(苷)溶解度好,毒性小,具有潜在开发应用价值。
具体实施方式
下面结合实施例对本发明作进一步描述。
实施例1:
1、20%黄芩甙(苷)液配方:按所需体积5000ml称取纯度>95%(如为99%)的黄芩甙(苷)粉1010克(5000ml*20%/99%)及抗氧化剂:硫代硫酸钠(每100ml加0.1g),添加注射用水至预配量体积5000ml的80%左右,用5%NaOH溶液以滴加或喷洒方式调节PH至7.0~7.4,必要时滴加或喷洒5%HCL进行调节,同时加入2%-5%的亲脂性助溶剂聚乙二醇,以增加其稳定性。按20%浓度加水定容并静置3小时,即5000毫升含1010克的黄芩苷,测渗透压合格。添加活性炭,每100ml液体加0.1g,于80℃条件下保温半小时,放置冷却3天~1周后,依次用滤纸、垂熔漏斗、0.22um微孔滤膜过滤,分装于玻璃容器内,115℃灭菌30分种,灯检提示澄明,静置无沉淀,并经动物实验证实其溶血、热原、血管脆性、无菌试验合格后即得。溶液颜色依据浓度不同可为棕色、棕红色。
2、保存方法:避光、阴凉保存
3、制剂用途:静脉注射、腹腔注射、肌肉注射、外用(眼、鼻、皮肤等)
4、临床推荐剂量:成人50-100mg/kg体重,静脉滴注或推注,一次/日,5-7天为一疗程,用于治疗各类感染性疾病。5%~10%可用于滴眼、滴鼻、灌肠等。5%~20%可外用于治疗溃疡、烧创伤创面、感染切口等。
5、小鼠静脉注射20%黄芩甙注射液的急性毒性实验(LD50)。计算半数致死量LD50(Bliss’s法)
