生物活性&实验参考方法
靶点
α2-adrenergic receptor ( Ki = 1.08 nM )
α2A-adrenergic receptor (Ki = 0.08 nM) [1]
- α2B-adrenergic receptor (Ki = 0.25 nM) [1]
- α2C-adrenergic receptor (Ki = 0.17 nM) [1]
- α1-adrenergic receptor (Ki = 640 nM, 8000-fold lower affinity than α2A subtype) [1]
体外研究 (In Vitro)
右美托咪定具有相对较高的 α2/α1 活性比率(1620:1,而可乐定为 220:1),因此被认为是 α2 受体的完全激动剂。这可能会产生更有效的镇静作用,而不会因 α1 受体激活而对心血管产生不良影响。右美托咪定的 2 小时半衰期比可乐定短近 4 倍,这增加了连续输注右美托咪定用于镇静的可能性。右美托咪定还具有保留最低肺泡麻醉浓度 (MAC) 的特性,但其作为麻醉佐剂的使用因持续低血压而变得复杂,需要静脉输液和血管加压药。此外,大剂量使用会因α2受体介导的血管收缩而导致高血压变得复杂。
大鼠大脑皮层膜制备物与Dexmedetomidine(0.01-100 nM)孵育后,高亲和力结合α2-肾上腺素受体各亚型,其Ki值较α1受体低7000-8000倍,显示出极强的亚型选择性[1]
- 原代大鼠皮质神经元经Dexmedetomidine(10 nM)处理后,通过α2-肾上腺素受体激活抑制毛喉素诱导的cAMP蓄积达68%,降低神经元兴奋性[3]
- Dexmedetomidine(1-10 μM)呈剂量依赖性抑制脂多糖(LPS)诱导的小鼠腹腔巨噬细胞释放肿瘤坏死因子-α(TNF-α),10 μM时抑制率达42%,发挥抗炎作用[3]
体内研究 (In Vivo)
美托咪定(10-100 μg/kg;静脉注射,间隔 5 分钟)会导致给予戊巴比妥的大鼠出现剂量依赖性瞳孔扩张[1]。
健康志愿者静脉注射Dexmedetomidine(0.5 μg/kg)后10分钟内出现轻至中度镇静(Ramsay镇静评分=4),静息心率降低18次/分钟,平均动脉压降低12 mmHg,且无显著呼吸抑制[2]
- 大鼠肌内注射Dexmedetomidine(50 μg/kg)后,镇静持续150分钟,热痛阈值较基线提高65%(通过甩尾试验评估)[3]
- 儿童术前口服Dexmedetomidine(2 μg/kg),给药后60分钟镇静评分(1-5分制)达3.8±0.5,与口服咪达唑仑(0.5 mg/kg)疗效相当,且不良反应更少(如呕吐发生率:3% vs. 12%)[3]
- 麻醉犬静脉注射Dexmedetomidine(10 μg/kg)后15分钟给予异氟醚麻醉,异氟醚的最低肺泡有效浓度(MAC)降低30%,术中血流动力学参数稳定[1]
酶活实验

细胞实验
神经元cAMP抑制实验:原代大鼠皮质神经元接种于24孔板,培养7天。用Dexmedetomidine(0.1-100 nM)预处理细胞30分钟后,用毛喉素(10 μM)刺激15分钟。裂解细胞后,采用竞争性ELISA试剂盒检测cAMP水平[3]
- 巨噬细胞抗炎实验:收集小鼠腹腔巨噬细胞接种于96孔板,培养24小时后用Dexmedetomidine(1-10 μM)预处理1小时,再暴露于LPS(1 μg/mL)6小时。ELISA法定量培养上清液中的TNF-α浓度[3]
动物实验
雌性Sprague-Dawley大鼠(270-350 g)
1、5、10、50、100 mg/kg
静脉注射,每5分钟一次
健康志愿者(n=12)接受静脉输注右美托咪定(0.5 μg/kg,10分钟内输注完毕),溶于0.9%生理盐水中。每5分钟监测一次镇静评分、心率、平均动脉压和呼吸频率,持续60分钟[2]
- 雄性Sprague-Dawley大鼠(10周龄)随机分为对照组和治疗组。右美托咪定(50 μg/kg)通过肌内注射给药。通过观察运动活动记录镇静持续时间,并使用甩尾试验每隔30分钟测量一次热痛阈值[3]
- 麻醉的比格犬(n=6)在异氟烷麻醉前15分钟接受静脉注射右美托咪定(10 μg/kg)。记录维持麻醉所需的异氟烷最小肺泡浓度(MAC),并在整个手术过程中监测血流动力学参数(心率、血压)[1]
- 接受择期手术的儿童(3-12岁,n=60)被随机分配到口服右美托咪定(2 μg/kg,溶于果汁)或口服咪达唑仑(0.5 mg/kg),于麻醉诱导前60分钟服用。记录镇静评分、面罩诱导的依从性以及不良事件[3]
药代性质 (ADME/PK)
吸收、分布和排泄
一项质量平衡研究表明,静脉注射放射性标记的右美托咪定后,9天后平均95%的放射性物质从尿液中回收,4%从粪便中回收。对尿液中排泄的放射性物质进行分馏分析表明,N-葡萄糖醛酸化产物约占累积尿排泄量的34%。大部分代谢物经尿液排出。

毒性/毒理 (Toxicokinetics/TK)
妊娠期和哺乳期影响
◉ 哺乳期用药概述
有限的数据表明,静脉输注结束后 4 至 6 小时内,极少量的右美托咪定会分泌到乳汁中。输注结束后 24 小时内,乳汁中不再含有该药物。舌下含服后乳汁中的药物含量预计低于静脉输注后的含量。由于乳汁中的药物剂量低且口服生物利用度差,预计右美托咪定不会对母乳喂养的婴儿或新生儿造成不良影响。舌下含服期间,应监测母乳喂养婴儿的烦躁情况。
◉ 对母乳喂养婴儿的影响
截至修订日期,未找到相关的已发表信息。
◉ 对泌乳和母乳的影响
一项双盲研究将 160 名接受择期剖宫产且行脊髓麻醉的女性随机分为两组,一组接受舒芬太尼进行患者自控静脉镇痛(标准治疗),另一组在标准治疗的基础上加用右美托咪定。右美托咪定的给药剂量为 5 mcg/kg,随后以 0.5 mcg/kg/小时的速度持续输注,直至手术结束。后一组患者术后接受右美托咪定联合舒芬太尼进行患者自控静脉镇痛,持续 2 天。接受右美托咪定治疗的患者首次泌乳时间更短(28 小时 vs 34 小时),更快实现纯母乳喂养(8 天 vs 11 天),并且在产后第二天乳汁量更多。
在一项对接受剖宫产的女性进行的回顾性研究中,比较了 3 种方案:麻醉前和分娩期间使用右美托咪定(n = 115)、麻醉前和分娩期间使用生理盐水,分娩后使用右美托咪定(n = 109)以及麻醉前和分娩期间使用生理盐水(n = 168)。接受右美托咪定麻醉前和分娩期间的女性在住院期间服用舒芬太尼和昂丹司琼的剂量较少,且首次泌乳时间略短于其他组的女性(25 分钟 vs 27 至 28 分钟)。

- 右美托咪定在人血浆中的血浆蛋白结合率为94%,在大鼠血浆中的血浆蛋白结合率为91% [2]
