产品描述
Bupivacaine HCl (AH250; HSDB7790; SKY0402; AH-250; Win-11318; HSDB-7790; SKY-0402; Marcaine) 是布比卡因的盐酸盐,是一种有效的 cAMP 生成抑制剂,也与细胞内部分结合电压门控钠通道并阻止钠流入神经细胞。布比卡因是一种用于冷冻特定区域组织的药物。它的给药方式是将其注射到该区域、供应该区域的神经周围或椎管的硬膜外腔中。它可以与少量肾上腺素混合,以使其持续时间更长。布比卡因与电压门控钠通道的细胞内部分结合,阻止钠流入神经细胞,从而防止去极化。

Bupivacaine HCl (HSDB 7790) primarily targets voltage-gated sodium channels [1]
It also exerts antitumor effects on gastric cancer cells via targets independent of sodium channel blockade [2]
体外研究 (In Vitro)
在与中枢敏化密切相关的脊髓背角区域,盐酸布比卡因可阻断 NMDA 受体介导的突触传递 [1]。盐酸布比卡因将半最大激活/失活膜电位移向稍微更负的膜电位,这对通道激活和稳态失活的电压依赖性有影响。 SCN5A 通道对盐酸布比卡因的 IC50 为 2.18±0.16 μM,这表明在非活性状态下有轻微的敏感性[2]。盐酸布比卡因的 IC50 为 16.5 μM,剂量依赖性且可逆地抑制 SK2 通道 [3]。
作为局部麻醉药,Bupivacaine HCl(1-100 μM)剂量依赖性阻滞神经元细胞的电压门控钠通道,抑制钠离子内流和动作电位传导;10 μM 时在静息膜电位下实现 90% 钠通道阻滞 [1]

- 对正常人胃上皮细胞(GES-1)毒性较低:1 mM 浓度处理 72 小时后细胞活力仍 >80% [2]
体内研究 (In Vivo)
Bupivacaine 不仅能诱导大鼠肌浆网 (SR) 释放 Ca2+,还能抑制 SR 对 Ca2+ 的摄取,这主要受 SR Ca2+ 三磷酸腺苷酶活性的调节。
在裸鼠 MGC-803 胃癌异种移植模型中,腹腔注射 Bupivacaine HCl(20 mg/kg,隔日一次,连续 21 天)的肿瘤生长抑制率(TGI)达 56%,肿瘤重量从溶媒组的 1.1 g 降至 0.49 g;肿瘤组织中 TUNEL 阳性凋亡细胞比例达 35%(溶媒组为 7%),p-AKT/p-mTOR 表达降低 [2]

药代性质 (ADME/PK)
吸收、分布和排泄
局部麻醉药的全身吸收取决于给药剂量和浓度,以及给药总量。影响全身吸收速率的其他因素包括给药途径、给药部位的血流量以及麻醉溶液中是否存在肾上腺素。与美洛昔康配制的布比卡因用于滴注后,单次不同剂量的给药后,其全身指标各不相同。在接受拇外翻切除术的患者中,60 mg 布比卡因的 Cmax 为 54 ± 33 ng/mL,Tmax 中位数为 3 小时,AUC∞ 为 1718 ± 1211 ng·h/mL。在疝修补术中使用的 300 mg 剂量,相应的数值分别为 271 ± 147 ng/mL、18 小时和 15,524 ± 8921 ng·h/mL。最后,在全膝关节置换术中使用的 400 mg 剂量,其 21 小时和 38,173 ± 29,400 ng/mL 的血药浓度分别为 695 ± 411 ng/mL 和 38,173 ± 29,400 ng/mL。
仅有 6% 的布比卡因以原形经尿液排出。
盐酸布比卡因被吸收入血后,其与血浆蛋白的结合率高于其他任何局部麻醉药;据报道,布比卡因的结合率为 82-96%。盐酸布比卡因是所有肠外局部麻醉药中胎盘转运程度最低的,因此可能对胎儿的抑制作用最小。
妊娠大鼠在 15 分钟内以 0.33 mg·kg⁻¹·min⁻¹ 的速率接受静脉输注布比卡因。胎儿在输注结束时或给药后 2 小时或 4 小时娩出。采用毛细管气相色谱-质谱联用技术测定母体和胎儿血液及组织样本中布比卡因及其代谢物的浓度。布比卡因的消除半衰期为37.7分钟。主要代谢物为3'-羟基布比卡因。给药结束时,所有样本中均检测到布比卡因和3'-羟基布比卡因。血浆中布比卡因的胎儿与母体浓度比为0.29,胎盘中为0.63。羊膜中布比卡因浓度最高,是母体血浆浓度的3倍,是胎儿血浆浓度的11倍。给药4小时后,所有母体和胎儿样本中均检测不到布比卡因,而除胎儿血浆和心脏外,所有组织中仍存在3'-羟基布比卡因。这些数据表明,胎盘两侧、羊膜和子宫肌层均吸收了大量的布比卡因。除胎儿血浆和心脏样本外,所有组织中均存在3'-羟基布比卡因,即使母体化合物已无法检测到。
在人体注射盐酸布比卡因进行尾部、硬膜外或周围神经阻滞后,血液中布比卡因的峰值浓度在30至45分钟内达到,随后在接下来的3至6小时内下降至可忽略不计的水平。
直接静脉注射盐酸布比卡因后的血浆药代动力学研究表明,其符合三室开放模型。第一室代表药物在血管内的快速分布。第二室代表药物在脑、心肌、肺、肾和肝等高灌注器官中的平衡。第三个隔室代表药物与灌注不良的组织(例如肌肉和脂肪)的平衡。药物从组织分布中的消除主要取决于循环中结合位点将其运送到肝脏进行代谢的能力。

代谢/代谢物
酰胺类局部麻醉药(例如布比卡因)主要在肝脏中通过与葡萄糖醛酸结合进行代谢。布比卡因的主要代谢物是 2,6-哌啶甲酰亚胺,主要由细胞色素 P450 3A4 催化。
妊娠大鼠在 15 分钟内以 0.33 mg·kg-1·min-1 的速率接受布比卡因静脉输注。胎儿在输注结束时或给药后2小时或4小时娩出。采集母体和胎儿的血液和组织样本,采用毛细管气相色谱-质谱法测定布比卡因及其代谢物。布比卡因的消除半衰期为37.7分钟。主要代谢物为3'-羟基布比卡因。给药结束时,所有样本中均检测到布比卡因和3'-羟基布比卡因。血浆中布比卡因的胎儿与母体浓度比为0.29,胎盘中为0.63。羊膜中布比卡因浓度最高:比母体血浆高3倍,比胎儿血浆高11倍。给药4小时后,在所有母体和胎儿样本中均检测不到布比卡因,而3'-羟基布比卡因仍存在于除胎儿血浆和心脏以外的所有组织中。这些数据表明,胎盘两侧以及羊膜和子宫肌层均吸收了大量的布比卡因。即使母体化合物已无法检测,除胎儿血浆和心脏样本外,所有组织中仍存在3'-羟基布比卡因。
盐酸布比卡因主要通过N-去烷基化代谢为哌啶基二甲苯胺(PPX),该过程可能发生在肝脏。布比卡因主要以少量PPX、原药(5%)和其他尚未鉴定的代谢物的形式经尿液排出。酰胺类局部麻醉药(如布比卡因)主要在肝脏中通过与葡萄糖醛酸结合代谢。布比卡因的主要代谢物是2,6-哌啶甲酰亚胺,主要由细胞色素P450 3A4催化。消除途径:仅有6%的布比卡因以原药形式经尿液排出。半衰期:成人为2.7小时,新生儿为8.1小时。布比卡因与美洛昔康联合用于术后镇痛的中位半衰期为15-17小时,具体时间取决于剂量和给药部位。
妊娠大鼠接受布比卡因静脉输注,输注速率为0.33 mg·kg⁻¹·min⁻¹,输注时间为15分钟。胎儿在输注结束时或给药后2小时或4小时娩出。采集母体和胎儿的血液和组织样本,采用毛细管气相色谱-质谱法测定布比卡因及其代谢物。布比卡因的消除半衰期为 37.7 分钟。
盐酸布比卡因的消除半衰期在成人中为 1.5-5.5 小时,在新生儿中为 8.1 小时。
人体药代动力学:硬膜外注射盐酸布比卡因(15 mL 0.5% 溶液)后,血浆峰浓度 (Cmax) 为 2.8 μg/mL,末端半衰期 (t1/2) 为 2.7 小时,曲线下面积 (AUC0-∞) 为 12.6 μg·h/mL [1]
- 它主要通过细胞色素 P450 酶(CYP3A4、CYP2C9)在肝脏中代谢,其中 70% 的代谢物经尿液排泄,30% 经粪便排泄 [1]
- 布比卡因的人体血浆蛋白结合率盐酸的浓度在治疗浓度下为 95-98% [1]
- 人体分布容积 (Vd) 为 1.4 L/kg [1]
毒性/毒理 (Toxicokinetics/TK)
毒性概述
布比卡因是一种胆碱酯酶或乙酰胆碱酯酶 (AChE) 抑制剂。胆碱酯酶抑制剂(或“抗胆碱酯酶”)可抑制乙酰胆碱酯酶的活性。由于乙酰胆碱酯酶具有重要的生理功能,干扰其活性的化学物质是强效神经毒素,低剂量即可引起唾液分泌过多和流泪,随后出现肌肉痉挛,最终导致死亡。神经毒气和许多杀虫剂中使用的物质已被证实可通过与乙酰胆碱酯酶活性位点中的丝氨酸残基结合而发挥作用,从而完全抑制该酶的活性。乙酰胆碱酯酶可分解神经递质乙酰胆碱,乙酰胆碱在神经和肌肉连接处释放,使肌肉或器官放松。乙酰胆碱酯酶抑制剂的作用机制是使乙酰胆碱积累并持续发挥作用,从而导致神经冲动不断传递,肌肉收缩无法停止。最常见的乙酰胆碱酯酶抑制剂是含磷化合物,这类化合物的作用机制是与酶的活性位点结合。其结构要求为:一个磷原子连接两个亲脂基团、一个离去基团(例如卤化物或硫氰酸酯)和一个末端氧原子。
毒性数据
在恒河猴中,布比卡因的平均致痫剂量为 4.4 mg/kg,平均动脉血浆浓度为 4.5 mcg/mL。
LD50:6 至 8 mg/kg(静脉注射,小鼠)
LD50:38 至 54 mg/kg(皮下注射,小鼠)
相互作用
对于正在服用单胺氧化酶抑制剂 (MAOI) 或曲替林或丙咪嗪类抗抑郁药的患者,应极其谨慎地使用含有血管收缩剂(例如肾上腺素)的盐酸布比卡因溶液,因为可能导致严重的持续性高血压。
布比卡因盐酸肾上腺素(1:200,000)或其他血管加压药不应与麦角类催产药同时使用,因为可能发生严重的持续性高血压。
非人类毒性值
小鼠皮下注射LD50 38-54 mg/kg
小鼠静脉注射LD50 6-8 mg/kg
中枢神经系统 (CNS) 毒性:在人类中,血浆浓度 >4 μg/mL 可能导致头晕(25% 的患者)、耳鸣(18%)和惊厥(罕见,<1%)[1]
- 心血管毒性:高剂量(静脉注射 >4 mg/kg)可能诱发心动过缓、低血压和心律失常;人体最小中毒静脉注射剂量约为 2 mg/kg [1]
- 动物毒性:盐酸布比卡因的 LD50 为 25 mg/kg(小鼠腹腔注射)和 10 mg/kg(大鼠静脉注射)[1]
- 用盐酸布比卡因(20 mg/kg,隔日一次,连续 21 天)治疗的小鼠,肝脏、肾脏或心脏未检测到明显的组织病理学异常;体重减轻 <4% [2]

其他信息
治疗用途
盐酸布比卡因用于浸润麻醉以及外周神经阻滞、交感神经阻滞和硬膜外(包括尾部)阻滞麻醉。0.75%的布比卡因溶液(溶于8.25%葡萄糖溶液)用于脊髓麻醉。布比卡因不用于产科宫颈旁阻滞或局部麻醉。/用途详见美国产品标签/
盐酸布比卡因适用于外科手术、牙科和口腔外科手术、诊断和治疗操作以及产科手术的局部或区域麻醉或镇痛。仅0.25%和0.5%浓度的布比卡因可用于产科麻醉。 /使用说明见美国产品标签/
药物警告
由于0.75%盐酸布比卡因溶液用于产科麻醉与产科患者心脏骤停、复苏困难或死亡相关,因此不再推荐将其用于产科麻醉。心脏骤停的发生可能是由于全身毒性引起的癫痫发作,而癫痫发作显然是由于意外的血管内注射所致。
局部麻醉药应仅由精通剂量相关毒性及其他可能由麻醉阻滞引起的急性紧急情况的诊断和处理的临床医生使用,并且必须在确保氧气、其他复苏药物、心肺复苏设备以及妥善处理毒性反应和相关紧急情况所需的人员资源随时可用后方可使用。
剂量相关毒性、任何原因导致的通气不足和/或敏感性改变若未能及时妥善处理,可能导致酸中毒、心脏骤停,甚至死亡。/局部麻醉药/
在积累更多关于该药物用于儿科患者的数据之前,盐酸布比卡因溶液不应用于12岁以下儿童,用于脊髓麻醉的溶液不应用于18岁以下儿童。
一些市售的盐酸布比卡因制剂含有焦亚硫酸钠,这是一种亚硫酸盐,可能在某些易感人群中引起过敏反应,包括过敏性休克和危及生命或较轻的哮喘发作。亚硫酸盐过敏在普通人群中的总体患病率尚不清楚,但可能较低;这种敏感性在哮喘患者中似乎比非哮喘患者更常见。

药效学
布比卡因是一种广泛使用的局部麻醉剂。在全髋关节置换术前,通常通过脊髓注射给予布比卡因。它也常被注射到手术伤口部位,以减轻术后长达20小时的疼痛。与其他局部麻醉剂相比,它的作用持续时间较长。但大剂量使用时,它对心脏的毒性也最大。这个问题促使人们使用其他长效局部麻醉剂:罗哌卡因和左布比卡因。左布比卡因是布比卡因的衍生物,具体来说是其对映体。局部麻醉剂的全身吸收会对心血管系统和中枢神经系统产生影响。在治疗剂量下达到的血药浓度范围内,心脏传导、兴奋性、不应期、收缩力和外周血管阻力的变化极小。然而,中毒血药浓度会抑制心脏传导和兴奋性,可能导致房室传导阻滞、室性心律失常和心脏骤停,有时甚至会导致死亡。此外,心肌收缩力也会降低,并伴有外周血管舒张,从而导致心输出量和动脉血压下降。局部麻醉药经全身吸收后,可引起中枢神经系统兴奋、抑制或两者兼有。
盐酸布比卡因是一种酰胺类局部麻醉药,临床上适用于硬膜外麻醉、脊髓麻醉和周围神经阻滞麻醉,以及术后镇痛[1]。
其核心麻醉机制涉及可逆性阻滞神经元膜上的电压门控钠通道,从而阻止钠离子内流并抑制神经冲动传导[1]。
除麻醉作用外,它还通过多种不依赖于钠通道阻滞的机制对胃癌具有抗肿瘤活性:诱导caspase依赖性细胞凋亡、抑制PI3K/AKT/mTOR信号通路以及抑制肿瘤细胞增殖和克隆形成[2]。
与短效局部麻醉药相比,它具有更高的效力和更长的作用持续时间,但需要谨慎用药以避免中枢神经系统和心血管毒性[1]。该药物对胃癌细胞表现出选择性毒性,对正常胃上皮细胞的损伤极小,提示其具有作为辅助抗肿瘤药物的潜力[2]

  • 计算制备已知体积和浓度的溶液所需的化合物的质量
  • 计算将已知质量的化合物溶解到所需浓度所需的溶液体积
  • 计算特定体积中已知质量的化合物产生的溶液的浓度
使用摩尔浓度计算器计算摩尔浓度的示例如下所示:
假如化合物的分子量为350.26 g/mol,在5mL DMSO中制备10mM储备液所需的化合物的质量是多少?
  • 在分子量(MW)框中输入350.26
  • 在“浓度”框中输入10,然后选择正确的单位(mM)
  • 在“体积”框中输入5,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案17.513 mg出现在“质量”框中。以类似的方式,您可以计算体积和浓度。

稀释计算器可计算如何稀释已知浓度的储备液。例如,可以输入C1、C2和V2来计算V1,具体如下:

制备25毫升25μM溶液需要多少体积的10 mM储备溶液?
使用方程式C1V1=C2V2,其中C1=10mM,C2=25μM,V2=25 ml,V1未知:
  • 在C1框中输入10,然后选择正确的单位(mM)
  • 在C2框中输入25,然后选择正确的单位(μM)
  • 在V2框中输入25,然后选择正确的单位(mL)
  • 单击“计算”按钮
  • 答案62.5μL(0.1 ml)出现在V1框中
g/mol

分子量计算器可计算化合物的分子量 (摩尔质量)和元素组成,具体如下:

注:化学分子式大小写敏感:C12H18N3O4  c12h18n3o4
计算化合物摩尔质量(分子量)的说明:
  • 要计算化合物的分子量 (摩尔质量),请输入化学/分子式,然后单击“计算”按钮。
分子质量、分子量、摩尔质量和摩尔量的定义:
  • 分子质量(或分子量)是一种物质的一个分子的质量,用统一的原子质量单位(u)表示。(1u等于碳-12中一个原子质量的1/12)
  • 摩尔质量(摩尔重量)是一摩尔物质的质量,以g/mol表示。
/

配液计算器可计算将特定质量的产品配成特定浓度所需的溶剂体积 (配液体积)

  • 输入试剂的质量、所需的配液浓度以及正确的单位
  • 单击“计算”按钮
  • 答案显示在体积框中
动物体内实验配方计算器(澄清溶液)
第一步:请输入基本实验信息(考虑到实验过程中的损耗,建议多配一只动物的药量)
第二步:请输入动物体内配方组成(配方适用于不溶/难溶于水的化合物),不同的产品和批次配方组成不同,如对配方有疑问,可先联系我们提供正确的体内实验配方。此外,请注意这只是一个配方计算器,而不是特定产品的确切配方。

计算结果:

工作液浓度 mg/mL;

DMSO母液配制方法 mg 药物溶于 μL DMSO溶液(母液浓度 mg/mL)。如该浓度超过该批次药物DMSO溶解度,请首先与我们联系。

体内配方配制方法μL DMSO母液,加入 μL PEG300,混匀澄清后加入μL Tween 80,混匀澄清后加入 μL ddH2O,混匀澄清。

(1) 请确保溶液澄清之后,再加入下一种溶剂 (助溶剂) 。可利用涡旋、超声或水浴加热等方法助溶;
            (2) 一定要按顺序加入溶剂 (助溶剂) 。
