Description

一种雷诺嗪缓释组合物及其制备方法 技术领域
本发明涉及药物制剂领域,具体涉及一种雷诺嗪缓释组合物及其制备方法。
背景技术
慢性心绞痛(Chronic angina pectoris)系指某种因素引起冠状动脉供血不足,心肌发生急剧、暂时的缺血与缺氧,引起阵发性、持续时间短暂,前胸压榨性疼痛为主要表现的临床综合症。症状特点为前胸阵发性、压榨性疼痛,疼痛主要位于胸骨后部,可放射至心前区与左上肢,劳动或情绪激动时常发生,每次发作持续3~5分钟,可数日一次,也可一日数次。本病多见于男性,多数40岁以上,劳累、情绪激动、饱食、受寒、阴雨天气、急性循环衰竭等为常见诱因。
雷诺嗪(ranolazine),化学名为(±)-N-(2,6-二甲基苯基)-4-[2-羟基-3-(2-甲氧基苯氧基)-丙基]-1-哌嗪乙酰胺、或其对映异构体(R)-(+)-N-(2,6-二甲基苯基)-4-[2-羟基-3-(2-甲氧基苯氧基)-丙基]-1-哌嗪乙酰胺、和(S)-(+)-N-(2,6-二甲基苯基)-4-[2-羟基-3-(2-甲氧基苯氧基)-丙基]-1-哌嗪乙酰胺、及其可接受的盐、和其混合物。雷诺嗪是一种局部脂肪氧化酶抑制剂,作用机制为钙离子通道拮抗剂,通过酶调节作用降低心脏需氧量,增加葡萄糖氧化,改善氧供需间的不平衡,缓解局部心肌缺血和抗心绞痛的症状,同时对血流动力学无影响,能提高心绞痛患者的生活质量,一般用于治疗慢性稳定型心绞痛。
雷诺嗪结构式为:
Figure PCTCN2020079856-appb-000001
2006年1月27日,由CV Therapeutics公司开发的新药雷诺嗪缓释片(Ranexa TM)获得美国FDA批准上市,用于治疗慢性心绞痛。2008年11月,FDA批准Ranexa TM作为一线药物用于治疗慢性心绞痛,也是唯一不引起心率和血压改变的抗心绞痛药物。
雷诺嗪本身在酸中溶解度较高,随着pH值的增高,其药物溶解度逐渐降低,而且其血浆半衰期相对较短,常规口服剂型使药物在胃中快速溶解、吸收和清除,一方面容易引起药物的血药浓度大范围波动,另一方面作用时间短,需要频繁口服给药。目前国内雷诺嗪缓释片均处于审评状态,有12家获得临床批件,而原研进口国内还处于验证性临床排队待审评状态, 所以目前还没有一款雷诺嗪制剂在国内上市。
美国专利US5506229的实施例描述了一种胶囊控释制剂,该胶囊由外包控制释放聚合物的雷诺嗪和微晶纤维素的微丸组成,用药次数为一天2次。中国专利CN1891218A公开了一种包含40~90wt%的盐酸雷诺嗪,7~40wt%的缓释基质,2~15wt%的粘合剂,0.5~5wt%的润滑剂的盐酸雷诺嗪缓释片,缓释基质有羟丙甲基纤维素K100M、乙基纤维素(10CP)和Eudragit RS PO,制备工艺采用常规湿法制粒技术,先用混料的一部分做内芯片颗粒压制成内芯片,再用混料的另一部分做外层片颗粒,一起压成包芯片,一方面工艺复杂,放大生产困难,另一方面容易造成内芯片破裂或外层脱落,导致体内释放过快。中国专利CN1193757公开一种包含50%~95%重量的雷诺嗪和1%~20%重量的pH依赖性粘合剂的持续释片药物剂型。中国专利CN1193757的即时释放制剂是以胶囊或片剂口服形式给药的,该专利的持续释放制剂中的口服剂量是以雷诺嗪碱的片剂形式给药的。中国专利CN1193757公开了雷诺嗪碱相对不溶于pH大于6.5的水溶液,而pH小于6时溶解度突然增加。由于雷诺嗪碱在肠液中微溶至极微溶解,而该专利未能提供确切的数据证明pH依赖性粘合剂促雷诺嗪在肠道中释放,因此雷诺嗪碱的释放可能不完全从而导致人体吸收不完全。
针对现存的雷诺嗪在应用中碰到的问题,目前急需开发一种新型的雷诺嗪缓释片,使其在口服给药后,受到体内pH值变化影响较小,药物在体内持续平稳释放,以此维持雷诺嗪在血浆中的有效浓度并且减小浓度波动,从而更好地发挥药效。为解决这一技术问题,本发明人提供一种雷诺嗪缓释组合物及制备方法,制备方法易于放大生产,且得到的缓释组合物,可持续12小时释药,释药平稳,杜绝了突释现象的发生,稳定性考察结果显示活性成分稳定性好,市售包装在加速试验条件下放置6个月,活性成分的含量、有关物质、释放度等均未见明显变化且符合质量标准的要求。

实验例11
雷诺嗪普通片和雷诺嗪缓释片(单层片、双层片)的体外释放曲线比较
照溶出度测定法(中国药典2015年版四部附录XD第二法)装置,以0.1N盐酸900ml为溶出介质,转速50转,温度37.0℃±0.5℃,测定对比例2雷诺嗪普通片在5min、10min、15min、20min、30min、45min、60min的溶出度。结果见图1和表1。
照释放度测定法(中国药典2015年版四部附录XD第二法)装置,以0.1N盐酸(0~1小时)+pH5.0磷酸盐缓冲液(1~3小时)、pH6.8磷酸盐缓冲(3~12小时)为释放介质,体积900ml,转速为100rpm,温度37.0℃±0.5℃,分别测定1小时、2小时、4小时、6小时、8小时、10小时和12小时的释放度,结果见图2和表2。

根据图1、表1、图2、表2可知,对比例2普通片从10分钟开始,对比例1单层缓释片从4小时开始均出现明显的突释现象,而雷诺嗪双层缓释片12小时释放平稳,与原研释放一致,效果明显优于普通片和单层缓释片。

根据表3和表4可知,经过加速稳定性试验,对比例1和原研参比加速6个月含量明显降低,有关物质大幅度增加,溶出度也比0天明显加快;而自研雷诺嗪双层缓释片加速6个月含量没有降低,有关物质没有明显增加,溶出度变化幅度较小,稳定性明显优于单层缓释片。
综上,本发明实施例公开了一种雷诺嗪缓释组合物及其制备方法。通过使用本发明所述的具有调控层的新型骨架缓释片技术后,在常规骨架片的基础上增加了调控层,克服了现有技术中骨架缓释片的缺陷,制备的雷诺嗪缓释片与CV Therapeutics的上市品Ranexa TM缓释片相比,体外释放行为非常接近,同时技术简单,只需要普通双层压片技术即可实现,工艺要求低,成本低廉。
以上实施例的说明只是用于帮助理解本发明的方法及其核心思想。应当指出,对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以对本发明进行若干改进和修饰,这些改进和修饰也落入本发明权利要求的保护范围内。
