产品描述
罗哌卡因是一种有效的钠通道阻滞剂。罗哌卡因通过可逆地抑制钠离子流入而引起神经纤维冲动传导阻滞。 Ropivacaine 也是 K2P(双孔钾通道)TREK-1 的抑制剂(阻断剂/拮抗剂),对 COS-7 细胞膜的 IC50 为 402.7 μM。罗哌卡因用于缓解神经性疼痛。
生物活性&实验参考方法
靶点
Voltage-gated sodium channels (Na+ channels).
体内研究 (In Vivo)
罗哌卡因抑制压力引起的滤过系数 (Kf) 增加,而不影响肺动脉压 (Ppa)、肺毛细血管压 (Ppc) 和弥散特性 (ZC) [2]。罗哌卡因可防止 PaO2、肺湿干比和脉络膜体积维持在伪波形水平,从而证明压力引起的肺水肿和相关的高渗透性 [2]。与脉络膜肺相比,罗哌卡因可阻断硝基肺中压力引起的肺水肿
在单侧L5/L6脊神经结扎诱导的神经病理性疼痛大鼠模型中,单次硬膜外给予甲磺酸罗哌卡因注射液(200 µg 游离碱)能显著阻断机械性异常性疼痛(52.0%)和热痛觉过敏(70.9%),生物学半衰期约为3小时。
同等剂量的罗哌卡因游离碱缓释混悬液(蓖麻油基质)能显著延长抗异常性疼痛和抗痛觉过敏的持续时间,生物学半衰期分别为5.2±1.4小时和6.4±1.3小时。
两种剂型连续多日硬膜外给药(200 µg/天,连续3天)均未诱导镇痛耐受或效应增强。
术前单次硬膜外给予甲磺酸罗哌卡因注射液(200 µg,术前1小时)能延迟神经病理性疼痛的发展,将生物学半衰期从不到4小时延长至约1天。
术前单次硬膜外给予罗哌卡因缓释混悬液(200 µg)能进一步将生物学半衰期延迟至约2天。
术前连续多日硬膜外给予缓释混悬液(200 µg/天,连续3天)能进一步延长延迟效应,机械性异常性疼痛和热痛觉过敏的生物学半衰期分别达到75.3±15.9小时和78.5±7.4小时。[2]
动物实验
动物/疾病模型:成年SD(Sprague-Dawley)大鼠(300–400g)[1]
剂量:1 μM
给药途径:输注(加入灌注液储液罐)
实验结果:压力依赖性降低。滤过系数(Kf)增加。
使用成年雄性Wistar大鼠(240±20 g)。在异氟烷麻醉下,将聚乙烯导管(PE-10)手术植入腰椎硬膜外腔(L3-L4节段)进行给药。
在异氟烷麻醉下,通过单侧结扎L5和L6脊神经诱导神经性疼痛。
药物治疗时,罗哌卡因甲磺酸盐注射液用无菌生理盐水稀释。罗哌卡因缓释混悬液(蓖麻油溶剂中的游离碱,含苯甲醇和苯甲酸苄酯)直接使用或用其无菌油溶剂稀释。
硬膜外注射缓慢进行(30 秒内注射 100 µL),随后用 10 µL 生理盐水冲洗。
在已建立的神经病变模型中,大鼠每日接受单次或多次硬膜外注射 200 µg 游离罗哌卡因(两种制剂均可)或溶剂。在注射前和注射后多个时间点(例如,1.5、2.5、4、8、16 小时)评估疼痛行为(通过电子冯·弗雷试验评估机械性痛觉过敏,通过足底热痛觉过敏试验评估热痛觉过敏)。
在预防性研究中,于脊神经结扎手术前 1 小时给予单次或多次每日硬膜外注射,并在术后数天内评估疼痛行为。[2]
药代性质 (ADME/PK)
吸收、分布和排泄
罗哌卡因的药代动力学高度依赖于剂量、给药途径和患者病情。硬膜外给药后,罗哌卡因完全吸收,呈双相吸收。
静脉给药后,86%的给药剂量经尿液排泄,其中1%为原药。
血管内输注后,罗哌卡因的稳态分布容积为41±7升。罗哌卡因能够轻易穿过胎盘。
静脉给药后,罗哌卡因的平均血浆清除率为 387 ± 107 mL/min,游离血浆清除率为 7.2 ± 1.6 L/min,肾清除率为 1 mL/min。
代谢/代谢物
罗哌卡因代谢广泛,主要通过 CYP1A2 介导的芳香族羟基化作用生成 3-羟基罗哌卡因。尿液中排泄的主要代谢物是 N-去烷基化代谢物 (PPX) 和 3-羟基罗哌卡因。其他已鉴定的代谢物包括 4-羟基罗哌卡因、3-羟基-N-去烷基化代谢物 (3-OH-PPX) 和 4-羟基-N-去烷基化代谢物 (4-OH-PPX),以及 2-羟基甲基罗哌卡因(已鉴定但未定量)。游离的 PPX、3-羟基罗哌卡因和 4-羟基罗哌卡因在动物模型中表现出的药理活性低于罗哌卡因。罗哌卡因已知的人体代谢物包括 PPX 和 3-羟基罗哌卡因。肝脏代谢:罗哌卡因在肝脏中广泛代谢,主要通过细胞色素 P4501A 介导的芳香族羟基化作用生成 3-羟基罗哌卡因。单次静脉注射后,约 37% 的总剂量以游离和结合的 3-羟基罗哌卡因的形式经尿液排出。静脉注射后,罗哌卡因总剂量的 86% 经尿液排出,其中仅有 1% 为原形药物。
半衰期:约 4.2 小时。
生物半衰期
罗哌卡因的平均终末半衰期在血管内给药后为 1.8 ± 0.7 小时,在硬膜外给药后为 4.2 ± 1 小时。
大鼠硬膜外注射甲磺酸罗哌卡因的消除半衰期 (t1/2B) 约为 100 分钟。
罗哌卡因缓释混悬液(蓖麻油中的游离碱)由于从脂质库缓慢持续释放,其消除半衰期较甲磺酸盐注射液显著延长。本研究未提供该混悬液的确切半衰期值,但据称其半衰期显著延长。
硬膜外罗哌卡因的鞘内生物利用度较低,约为10%。[2]
毒性/毒理 (Toxicokinetics/TK)
毒性概述
局部麻醉药如罗哌卡因可阻断神经冲动的产生和传导,其作用机制可能是提高神经电兴奋阈值、减缓神经冲动的传播速度以及降低动作电位上升速率。具体而言,它们阻断钠通道,降低去极化和随后动作电位的发生概率。通常,麻醉的进展与受影响神经纤维的直径、髓鞘化程度和传导速度有关。
与布比卡因相比,罗哌卡因对中枢神经系统和心血管系统的毒性较小。
在本研究中,硬膜外注射罗哌卡因(60、180、600 µg)可导致大鼠出现剂量依赖性的、即刻的、可逆的后肢运动麻痹。在相同剂量下,缓释混悬液的麻痹持续时间比甲磺酸盐注射液更长。所采用的硬膜外给药方案未报告其他全身毒性或死亡病例。[2]

作用机制
罗哌卡因等局部麻醉药通过提高神经电兴奋阈值、减缓神经冲动的传播以及降低动作电位上升速率来阻断神经冲动的产生和传导。具体而言,它们阻断钠通道,降低去极化和随后的动作电位发生的概率。一般来说,麻醉的进展与受累神经纤维的直径、髓鞘化程度和传导速度有关。
药效学

罗哌卡因是一种长效酰胺类局部麻醉药,其化学结构与布比卡因和甲哌卡因类似。它广泛用于区域麻醉和硬膜外镇痛。
与布比卡因相比,罗哌卡因具有更好的感觉运动差异阻滞(在低于引起运动阻滞的剂量下即可有效镇痛)和更佳的毒性特征。
其作用机制涉及阻断电压门控钠通道,从而抑制神经元动作电位的产生和传导。这种方法尤其能有效抑制受损神经的异位放电,而异位放电正是导致神经性疼痛的原因之一。

这项研究表明,硬膜外罗哌卡因,尤其是缓释制剂,具有治疗神经性疼痛和提供预防性镇痛的潜力,且不会产生耐受性。[2]

  • Dose responses of epidural administration of ropivacaine both in mesylate injection and sustained release suspension form on motor paralysis duration (A) and latency (B) in rats. Data are presented as means ± SEM (n = 6 in each group). a denotes statistically significant difference of ropivacaine sustained release suspension compared to the ropivacaine mesylate group (P < 0.05 by a two-way repeated-measures ANOVA followed by a post-hoc Student-Newman-Keuls test).[2]. Li TF, et al. Epidural sustained release ropivacaine prolongs anti-allodynia and anti-hyperalgesia in developing and established neuropathic pain. PLoS One. 2015 Jan 24;10(1):e0117321.
  • Blockade effects of the subsequent first (A, B), second (C, D) and third (E, F) epidural administration of ropivacaine, both in mesylate injection and sustained release suspension form, on mechanical allodynia and heat hyperalgesia in spinal nerve ligation-induced neuropathic rats.Peripheral neuropathy was induced by unilateral L5/L6 spinal nerve ligation and approximately 7 days later. The rats received repetitive epidural injections for 3 days and the paw withdrawal responses to mechanical and radiate heat stimuli in both the ipsilateral and contralateral hind-limbs were subsequently (with 10-min interval) measured before and 1.5, 2.5, 4, 8, and 16 hrs after epidural injection. Data are presented as means ± S.E.M. (n = 6 in each group). a and b denote statistical significance of ropivacaine sustained release suspension compared to the normal saline group and ropivacaine mesylate group, respectively (P < 0.05 by a two-way ANOVA followed by a post-hoc Student-Newman-Keuls test).[2]. Li TF, et al. Epidural sustained release ropivacaine prolongs anti-allodynia and anti-hyperalgesia in developing and established neuropathic pain. PLoS One. 2015 Jan 24;10(1):e0117321.
  • Preemptive effects of epidural administration of ropivacaine both in mesylate injection and sustained release suspension form on mechanical allodynia and heat hyperalgesia in spinal nerve ligation-induced neuropathic rats.The rats received single-dose (A, B) or multi-daily (C, D) epidural administrations and underwent L5/L6 spinal nerve ligation surgery one hour after the final treatment. The paw withdrawal responses to mechanical and radiate heat stimuli in both the ipsilateral and contralateral hindlimbs were subsequently (with 10-min interval) measured 8 hrs after surgery and afterwards. Data are presented as means ± S.E.M. (n = 6 in each group). a and b denote statistical significance of ropivacaine sustained release suspension compared to the normal saline group and ropivacaine mesylate group, respectively (P < 0.05 by a two-way ANOVA followed by a post-hoc Student-Newman-Keuls test).[2]. Li TF, et al. Epidural sustained release ropivacaine prolongs anti-allodynia and anti-hyperalgesia in developing and established neuropathic pain. PLoS One. 2015 Jan 24;10(1):e0117321.
