Description
技术领域
本申请涉及但不限于药物制剂技术领域,特别涉及艾司氯胺酮液体制剂及其作为抗抑郁药物的用途。
背景技术
抑郁症是躁狂抑郁症的一种发作形式,以情感低落、思维迟缓、以及言语动作减少,迟缓为典型症状。抑郁症严重困扰患者的生活和工作,给家庭和社会带来沉重的负担,约15%的抑郁症患者死于自杀。世界卫生组织、世界银行和哈佛大学的一项联合研究表明,抑郁症已经成为中国疾病负担的第二大病。
近年来,氯胺酮作为精神科药物治疗抑郁症颇受关注,已有大量报道证明其抗抑郁作用。氯胺酮作为一个快速起效的抗抑郁药物,其机制可能是通过增加单胺释放或抑制突触前单胺再摄取,从而升高大脑单胺化合物水平来达到抗抑郁的作用。
氯胺酮为N-甲基-D-天门冬氨酸(NMDA)受体拮抗剂,目前临床使用的氯胺酮多为消旋体,含有两个对映体,即右旋氯胺酮和左旋氯胺酮。研究表明,右旋氯胺酮,即艾司氯胺酮(Esketamine)对NMDA、阿片受体、M胆碱受体的亲和力比左旋高约2~4倍,而对5-HT的抑制作用仅为左旋的50%。此外,氯胺酮在应用中出现幻觉、梦境等副作用主要由左旋型异构体产生。因此,艾司氯胺酮疗效更佳,致幻、成瘾等副作用更小。
美国强生(Johnson&Johnson)研制的一种新机制的抗抑郁药物,就是以盐酸艾司氯胺酮为主药的鼻喷雾剂,该品对难治性抑郁症和已有自杀倾向的患者具有速效、持久的强大疗效,并于2019年3月获批在美国首次上市。此外,该品分别于2013年和2016年获得FDA授予的治疗难治性抑郁症的突破性药物资格和治疗伴有紧迫自杀风险的重度抑郁症的突破性药物资格(BTD)。
虽然艾司氯胺酮通过鼻腔给药的形式已到达很好的抗抑郁效果,但是针对鼻腔有炎症或者鼻粘膜耐受性较差的患者,经鼻给药无法满足该类患者的药用需求;此外,对于已上市的盐酸艾司氯胺酮的鼻喷制剂,其经鼻给药的体积较小,为达到治疗剂量,该制剂中盐酸艾司氯胺酮浓度较高,接近艾司氯胺酮水溶饱和度。这种高浓度的盐酸艾司氯胺酮溶液在一定程度上会增加氯胺酮滥用的风险;再者,通过药代动力学研究发现,艾司氯胺酮经鼻喷给药,药物吸收速度快,但是鼻喷给药,体内药物吸收不好,生物利用度不高。因此,为了更好的扩展氯胺酮在抗抑郁的临床应用范围,满足更多抑郁症患者的需求,降低治疗成本,减轻患者家庭负担,亟需考虑其他有效的给药途径。

2、实验方案
本实验采用新西兰白兔,2.5kg~3.0kg,每组6只,雌雄各半。对比例1采用单侧经鼻给药,给药量为0.05ml/只(1喷);实施例1采用单侧口颊液给药,给药量为0.125ml/只;对比例2、对比例3采用单侧口颊膜给药,给药量为1片/只(7mg);对比例2、对比例3采用舌下给药,给药量为1片/只(7mg)。采血前将家兔置于兔固定盒中,采血方式为耳缘静脉采血,采集血液时间点为:0min(给药前),2min、5min、10min、15min、30min、60min、120min、240min。每个时间点取约1mL全血至含肝素钠的采血管中,4000rpm离心10min,离心得血浆样品,取上清液分装3份至0.5ml EP管中(前2份装150μl,多余血浆装于第3个冻存管中作为备份样),血浆样品分装处理后置于≤-80℃保存样本。
3、实验结果
表7:六组样品不同给药途径兔子药代实验结果
由表7和图1可知,在盐酸艾司氯胺酮兔子的不同给药途径组中,与经鼻给药组(对比例1)相比,口颊液的口颊给药组(实施例1)的Tmax与其相近,大约在4~7min内,而口溶膜组(对比例2、对比例3)的Tmax在20~60min的范围内,说明本申请的盐酸艾司氯胺口颊液的颊膜给药与其鼻喷的经鼻给药的起效时间类似,而口溶膜的起效时间慢。
由平均Cmax的数据可知,与经鼻给药组(对比例1)相比,口颊液的口颊给药组(实施例1)的Cmax明显增大,提高约1倍;而口溶膜组(对比例2、对比例3)的Cmax低于经鼻给药组,降低了约1~2倍,说明了本申请盐酸艾司氯胺酮口颊液颊膜给药的药物吸收较经鼻给药更高。
由表7和图2可知,与经鼻给药组(对比例1)相比,口颊液的口颊给药组(实施例1)的AUC0-240min明显增大(p<0.05),提高约1倍;而口溶膜组(对比例2、对比例3)的AUC0-240min与经鼻给药组相差不大(p>0.05),这个结果与Cmax的结果一致,进一步说明了本申请的盐酸艾司氯胺酮口颊液颊膜给药的体内药物吸收高于经鼻给药、口溶膜给药。
综上所述,盐酸艾司氯胺酮口颊液颊膜给药的体内药物吸收显著高于经鼻给药、口溶膜给药,提高约1倍,且这两种途径的起效时间相近,约4~7min,起效速度快于口溶膜给药。
本申请技术方案也可用于R-氯胺酮、氯胺酮或药学上可接受的盐的口颊液颊膜给药系统,通过调整或改变活性成分含量、可用于药学上的辅料种类、用量等手段达到本发明目的。
虽然本申请所揭露的实施方式如上,但所述的内容仅为便于理解本申请而采用的实施方式,并非用以限定本申请。任何本申请所属领域内的技术人员,在不脱离本申请所揭露的精神和范围的前提下,可以在实施的形式及细节上进行任何的修改与变化,但本申请的保护范围,仍须以所附的权利要求书所界定的范围为准。
