产品描述
雷贝拉唑 (LY-307640) 是一种新型、有效的第二代质子泵抑制剂 (PPI),用作抗溃疡药物。它不可逆地灭活胃 H+/K+-ATP 酶并诱导细胞凋亡。雷贝拉唑是一种尿苷核苷核糖水解酶 (UNH) 抑制剂,IC50 为 0.3 μM。雷贝拉唑可用于胃溃疡和胃食管反流的研究。它是一种部分可逆的胃质子泵抑制剂,也是ATP4的抑制剂。
生物活性&实验参考方法
体外研究 (In Vitro)
暴露于 0.2 mM 雷贝拉唑 16 小时后,人胃癌细胞表现出活力降低 [2]。在 MKN-28 细胞中,雷贝拉唑完全抑制 ERK1/2 磷酸化。胃癌细胞系 MKN-28 在酸性培养基(pH 5.4)中生长两个小时。在 MKN-28 细胞中,雷贝拉唑预处理(0.2 mM,2 小时)显着降低 ERK1/2 磷酸化 [2]。
体内研究 (In Vivo)
在雌性小鼠中,雷贝拉唑疗程(10 mg/kg;口服;每 48 小时一次,持续 18 周)导致血清钙水平、继发性甲状旁腺疾病和骨矿物质密度 (BMD) 显着降低。甲状腺功能亢进症[3]。
细胞实验
细胞活力测定[2]
细胞类型: 三种胃癌细胞系 KATO III、MKN-28 和 MKN-45
测试浓度: 0.2 mM
孵育持续时间:16 小时
实验结果:使用 KATO III 进行治疗后,所有测试的癌细胞系的活力均下降,并进行比较与 MKN-45 细胞相比,MKN-28 细胞的细胞活力显着降低。

细胞活力测定[2]
细胞类型: 三种胃癌细胞系(KATO III、MKN-28 和 MKN-45)[2]
测试浓度: 0.2 mM
孵育持续时间:2 小时预处理
实验结果: 导致强烈抑制ERK 1/2 在 MKN-28 细胞中磷酸化,但在 KATO III 和 MKN-45 细胞中未观察到类似的作用。
动物实验
动物/疾病模型:雌性瑞士白化小鼠(体重 18-26 克)[3]
剂量:10 mg/kg
给药途径:口服;每 48 小时一次,持续 18 周
实验结果:与载体处理组相比,血清钙水平显著降低(5.5±2.07 vs. 9.68±2.77)。
药代性质 (ADME/PK)
吸收、分布和排泄
绝对生物利用度约为52%。
单次口服20 mg 14C标记的雷贝拉唑后,约90%的药物经尿液排出,主要以硫醚羧酸、其葡萄糖醛酸苷和巯基尿酸代谢物的形式排出。
排泄:肾功能正常:约1至2小时。肝功能受损:2至6小时。
蛋白结合率:非常高;约96%与人血浆蛋白结合。
由于雷贝拉唑对酸不稳定,因此以缓释片形式给药,以便其能够相对完整地通过胃。雷贝拉唑离开胃后,在给药后1小时内即可被吸收。生物利用度约为52%。
尚不清楚雷贝拉唑是否会分布到人乳中。然而,在哺乳期大鼠中,乳汁中雷贝拉唑的浓度比血液中高2至7倍。
有关雷贝拉唑(共10项)的更多吸收、分布和排泄(完整)数据,请访问HSDB记录页面。
代谢/代谢物
肝脏代谢
约90%的雷贝拉唑剂量以代谢物的形式经尿液排出。这些代谢物主要包括硫醚羧酸(TCA)、TCA的葡萄糖醛酸苷和巯基尿酸。
雷贝拉唑代谢广泛。在人血浆中检测到的主要代谢物是硫醚和砜。未观察到这些代谢物具有显著的抗分泌活性。体外研究表明,雷贝拉唑主要在肝脏中经细胞色素P450 3A (CYP3A)代谢为砜类代谢物,并经细胞色素P450 2C19 (CYP2C19)代谢为去甲基雷贝拉唑。硫醚类代谢物是由雷贝拉唑还原而非酶促生成的。CYP2C19存在已知的遗传多态性,这是由于某些亚人群(例如3%至5%的白种人和17%至20%的亚洲人)存在CYP2C19缺陷所致。在这些亚人群中,雷贝拉唑代谢缓慢,因此他们被称为该药物的弱代谢者。
雷贝拉唑是雷贝拉唑(雷贝拉唑硫醚)的已知人体代谢产物。
生物半衰期
1-2 小时(血浆中)
血浆半衰期为 1 至 2 小时。
本研究旨在确定 20 mg 雷贝拉唑片剂在正常健康受试者中的绝对生物利用度,并与静脉注射 20 mg 雷贝拉唑进行比较。……每位受试者在研究开始时被随机分配,在第一阶段接受单次 20 mg 雷贝拉唑静脉注射或口服。……静脉注射剂量以 5 分钟的持续输注方式给药。口服雷贝拉唑钠后的消除半衰期(1.47±0.82 小时)明显长于静脉注射后的消除半衰期(1.02±0.63 小时),这可能是由于吸收速度比消除速度慢所致。
毒性/毒理 (Toxicokinetics/TK)
肝毒性
尽管雷贝拉唑应用广泛,但其引起肝损伤的病例却很少见。在大规模的雷贝拉唑长期试验中,血清ALT升高发生率低于1%,且与安慰剂或对照药物组的发生率相似。在大型药物性肝损伤病例系列研究中,雷贝拉唑仅导致少数有症状的急性肝损伤。目前仅有少数雷贝拉唑引起的临床明显肝病病例报道,且该损伤的特征尚未明确,但似乎与其他质子泵抑制剂相关的肝损伤特征相似。质子泵抑制剂引起的临床明显肝损伤通常在治疗的前4周内出现,症状包括黄疸、恶心和疲乏,以及肝细胞性或混合型血清酶升高。停药后通常可迅速恢复。皮疹、发热和嗜酸性粒细胞增多症很少见,自身抗体形成也很少见。已有报告显示再次用药后出现复发病例。
可能性评分:D(可能是临床上明显的肝损伤的罕见原因)。
妊娠和哺乳期影响
◉ 哺乳期用药概述
由于目前尚无关于哺乳期使用雷贝拉唑的信息,因此建议选择其他药物,尤其是在哺乳新生儿或早产儿时。
◉ 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。
◉ 对哺乳和母乳的影响
美国一项回顾性索赔数据库研究发现,质子泵抑制剂使用者发生男性乳房发育症的风险增加。
西班牙药物警戒系统发现,1982年至1983年间报告了一例90岁男性服用雷贝拉唑后出现男性乳房发育症的病例。 2006年。该反应发生在治疗32天后,停药后消退。
一篇综述文章报道,欧洲药物警戒中心数据库检索发现,雷贝拉唑相关不良反应包括11例男性乳房发育症、3例溢乳、2例乳房疼痛和1例乳房增大。世界卫生组织全球药物警戒数据库检索发现,雷贝拉唑相关不良反应包括38例男性乳房发育症、29例溢乳、28例乳房疼痛和5例乳房增大。
一名女性因腹泻和消化不良被处方甲硝唑400毫克,每日三次,以及含有雷贝拉唑20毫克和多潘立酮30毫克的复方制剂,每日一次。治疗3天后,
她出现双侧溢乳。雷贝拉唑和多潘立酮的联合用药被认为是导致不良反应的原因。
蛋白结合率
96.3%(与人血浆蛋白结合)
药物相互作用
华法林:潜在的药代动力学相互作用。质子泵抑制剂可能抑制华法林的代谢。单剂量研究中未发现具有临床意义的相互作用,但有报道称,同时服用这些药物的患者会出现国际标准化比值 (INR) 和凝血酶原时间 (PT) 升高;在与雷贝拉唑联合用药期间可能需要监测 INR 和 PT。
雷贝拉唑可能升高胃肠道 pH 值;正常受试者同时服用地高辛和雷贝拉唑会导致血清峰浓度升高 29%。
雷贝拉唑可能升高胃肠道 pH 值;酮康唑与雷贝拉唑合用导致雷贝拉唑生物利用度降低30%。
体外人肝微粒体孵育实验表明,雷贝拉唑抑制环孢素代谢的IC50值为62微摩尔,该浓度比健康志愿者连续14天服用20毫克雷贝拉唑后达到的Cmax高50倍以上。这种抑制程度与等浓度奥美拉唑的抑制程度相似。
雷贝拉唑、阿莫西林和克拉霉素联合用药导致雷贝拉唑和14-羟基克拉霉素的血浆浓度升高。

其他信息
治疗用途
抗溃疡药
雷贝拉唑适用于短期治疗(4-8周),以缓解糜烂性或溃疡性胃食管反流病的症状并促进其愈合。对于未愈合的患者,雷贝拉唑可额外治疗8周。雷贝拉唑也适用于维持糜烂性或溃疡性胃食管反流病的愈合。/美国产品标签包含/
雷贝拉唑适用于长期治疗病理性高分泌状态,包括卓-艾综合征。/美国产品标签包含/
雷贝拉唑适用于短期治疗(最长4周),以促进活动性十二指肠溃疡患者的愈合并缓解其症状。 /包含于美国产品标签/
药物警告
对于严重肝功能损害的患者,应谨慎用药,尤其因为缺乏该患者群体的临床数据。然而,每日20毫克的常用剂量不太可能导致雷贝拉唑蓄积,轻度至中度肝功能损害患者无需调整剂量。
雷贝拉唑治疗的症状缓解并不能排除胃肿瘤隐匿存在的可能性。约4%的患者在随访期间(长达40个月)未出现肠化生,且未观察到持续性变化。
使用质子泵抑制剂与某些感染(例如社区获得性肺炎)风险增加相关。
FDA妊娠风险类别:B /无证据表明对人类存在风险。尽管动物实验中发现了不良反应,但对孕妇进行的充分、控制良好的研究并未显示胎儿畸形风险增加;或者,在缺乏充分的人体研究的情况下,动物研究显示无胎儿风险。胎儿受损的可能性很小,但仍然存在。/

药效学
雷贝拉唑可抑制胃酸分泌。它能减轻胃食管反流病(GERD)或溃疡患者的症状,并预防食管或胃损伤。雷贝拉唑也适用于胃酸分泌过多的疾病,例如卓-艾综合征。雷贝拉唑也可与抗生素联合使用,以清除与某些溃疡相关的细菌。雷贝拉唑是一种选择性且不可逆的质子泵抑制剂,它通过特异性抑制壁细胞分泌表面的H+,K+-ATP酶来抑制胃酸分泌。这样一来,它就抑制了氢离子(通过与钾离子交换)最终转运到胃腔的过程。

注意: 以上为较为常见方法,仅供参考, InvivoChem并未独立验证这些配方的准确性。具体溶剂的选择首先应参照文献已报道溶解方法、配方或剂型,对于某些尚未有文献报道溶解方法的化合物,需通过前期实验来确定(建议先取少量样品进行尝试),包括产品的溶解情况、梯度设置、动物的耐受性等。

请根据您的实验动物和给药方式选择适当的溶解配方/方案:
1、请先配制澄清的储备液(如:用DMSO配置50 或 100 mg/mL母液(储备液));
2、取适量母液,按从左到右的顺序依次添加助溶剂,澄清后再加入下一助溶剂。以 下列配方为例说明 (注意此配方只用于说明,并不一定代表此产品 的实际溶解配方):
10% DMSO → 40% PEG300 → 5% Tween-80 → 45% ddH2O (或 saline);
假设最终工作液的体积为 1 mL, 浓度为5 mg/mL: 取 100 μL 50 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀/澄清;向上述体系中加入50 μL Tween-80,混合均匀/澄清;然后继续加入450 μL ddH2O (或 saline)定容至 1 mL;

3、溶剂前显示的百分比是指该溶剂在最终溶液/工作液中的体积所占比例;
4、 如产品在配制过程中出现沉淀/析出,可通过加热(≤50℃)或超声的方式助溶;
5、为保证最佳实验结果,工作液请现配现用!
6、如不确定怎么将母液配置成体内动物实验的工作液,请查看说明书或联系我们;
7、 以上所有助溶剂都可在 Invivochem.cn网站购买。
制备储备液 1 mg 5 mg 10 mg
1 mM 2.7821 mL 13.9105 mL 27.8211 mL
5 mM 0.5564 mL 2.7821 mL 5.5642 mL
10 mM 0.2782 mL 1.3911 mL 2.7821 mL

1、根据实验需要选择合适的溶剂配制储备液 (母液):对于大多数产品,InvivoChem推荐用DMSO配置母液 (比如:5、10、20mM或者10、20、50 mg/mL浓度),个别水溶性高的产品可直接溶于水。产品在DMSO 、水或其他溶剂中的具体溶解度详见上”溶解度 (体外)”部分;

2、如果您找不到您想要的溶解度信息,或者很难将产品溶解在溶液中,请联系我们;

3、建议使用下列计算器进行相关计算(摩尔浓度计算器、稀释计算器、分子量计算器、重组计算器等);

4、母液配好之后,将其分装到常规用量,并储存在-20°C或-80°C,尽量减少反复冻融循环。

  • Decline in cancer cell viability induced by rabeprazole and expression level analysis of α - and β-subunits of hydrogen/potassium adenosine triphosphatase (H+/K+-ATPase) in gastric cancer cells. (A) Rabeprazole attenuated the cell viability of the human gastric cancer cells. Following treatment with 0.2 mM of the proton pump inhibitor rabeprazole for 16 h, the cell viability of the MKN-28 cells significantly decreased compared with the KATO III and MKN-45 cells, respectively. *P<0.05 vs. the viability of the KATO III cells. #P<0.05 vs. the viability of the MKN-45 cells. (B) Expression level analysis of α - and β-subunits of H+/K+-ATPase in the gastric cancer cells. The α-subunit of H+/K+-ATPase was strongly expressed in the KATO III and MKN-28 cells, while being weakly expressed in the MKN-45 cells. The β-subunit of H+/K+-ATPase was equally expressed in the tested cancer cells. Glyceraldehyde 3-phosphate dehydrogenase (GAPDH) was used as an internal control to verify equal amounts of total cDNA in each sample. RT-PCR, reverse transcription polymerase chain reaction.[2].

  • Rabeprazole treatment induces apoptotic cell death in gastric cancer AGS cells. (A) Kinetics of apoptotic cell death (%) induced by rabeprazole. Exposure to 0.2 mM rabeprazole resulted in significant apoptosis in the AGS cells after 72 h. (B) Annexin V-FITC)/PI double staining fluorescence-activated cell sorting analysis. Cells were harvested, stained with annexin V-FITC/PI, and analyzed by flow cytometry following treatment with rabeprazole. Administration of rabeprazole to the AGS cells markedly increased the apoptosis rate, reaching 72.21±3.24% compared with 3.20±0.26% in the control group (P<0.01). FITC, fluorescein isothiocyanate; PI, propidium iodide.[2]. Mengli Gu, et al. Rabeprazole Exhibits Antiproliferative Effects on Human Gastric Cancer Cell Lines. Oncol Lett. 2014 Oct;8(4):1739-1744.
  • Effect of suppression of ERK 1/2 on cell viability. Following treatment with proton pump inhibitor rabeprazole or PD98059 (a potent ERK 1/2 inhibitor) for 2 h, the AGS cells were further cultured at various pH levels (pH 7.4, 6.4 or 5.4) for 16 h. (A) Administration of rabeprazole to the AGS cells at a dosage of 0.2 mM resulted in a marked attenuation in cancer cell viability at pH 5.4. *P<0.05 vs. 0 mM rabeprazole treatment at pH 5.4. #P<0.05 vs. 0.1 mM rabeprazole treatment at pH 5.4. ΔP<0.05 vs. 0.2 mM rabeprazole treatment at pH 7.4 or 6.4. (B) Pretreatment with 100 μM PD98059 significantly reduced the cell viability at pH 5.4. *P<0.05 vs. 0 μM PD98059 treatment at pH 5.4. #P<0.05 vs. 50 μM PD98059 treatment at pH 5.4. ΔP<0.05 vs. 100 μM PD98059 treatment at pH 7.4 or 6.4. (C) PD98059 and rabeprazole were each able to efficaciously inhibit the phosphorylation of ERK 1/2 in the AGS cells. P-ERK, phosphorylated extracellular signal-regulated protein kinase 1/2; Rabe, rabeprazole.[2]. Mengli Gu, et al. Rabeprazole Exhibits Antiproliferative Effects on Human Gastric Cancer Cell Lines.
