代谢
在吸收之后,文拉法辛在肝脏经历广泛的预处理系统代谢。它主要经历CYP2D6介导的脱甲基作用,形成其活性代谢物O-去甲基文拉法辛(ODV)。文拉法辛还可以通过CYP2C9、CYP2C19和CYP3A4介导的N-脱甲基作用形成N-去甲基文拉法辛(NDV),但这是一条次要的代谢途径。ODV和NDV进一步通过CYP2C19、CYP2D6和/或CYP3A4代谢,形成N,O-双去甲基文拉法辛(NODV),NODV可以进一步代谢形成N, N, O-三去甲基文拉法辛,随后可能发生葡萄糖醛酸化。
Following absorption, venlafaxine undergoes extensive presystemic metabolism in the liver. It primarily undergoes CYP2D6-mediated demethylation to form its active metabolite O-desmethylvenlafaxine (ODV). Venlafaxine can also undergo N-demethylation mediated by CYP2C9, and CYP2C19, and CYP3A4 to form N-desmethylvenlafaxine (NDV) but this is a minor metabolic pathway. ODV and NDV further metabolized by CYP2C19, CYP2D6 and/or CYP3A4 to form N,O-didesmethylvenlafaxine (NODV) and NODV can be further metabolized to form N, N, O-tridesmethylvenlafaxine, followed by a possible glucuronidation.

代谢
在吸收之后,文拉法辛在肝脏中经历广泛的预处理系统代谢,主要转化为O-去甲文拉法辛,但也转化为N-去甲文拉法辛、N,O-二去甲文拉法辛以及其他少量代谢物。体外研究表明,O-去甲文拉法辛的形成由CYP2D6催化;这一发现在一项临床研究中得到了证实,该研究发现CYP2D6平较低的患者("弱代谢者")与CYP2D6平正常的患者("广泛代谢者")相比,文拉法辛平增加,而O-去甲文拉法辛平降低。然而,CYP2D6弱代谢者和广泛代谢者之间的差异预计在临床上不会重要,因为文拉法辛O-去甲文拉法辛的总和在两组中相似,且文拉法辛O-去甲文拉法辛在药理作用上大约是等效和等效的。
Following absorption, venlafaxine undergoes extensive presystemic metabolism in the liver, primarily to O-desmethylvenlafaxine, but also to N-desmethylvenlafaxine, N,O-didesmethylvenlafaxine, and other minor metabolites. In vitro studies indicate that the formation of O-desmethylvenlafaxine is catalyzed by CYP2D6; this has been confirmed in a clinical study showing that patients with low CYP2D6 levels ("poor metabolizers") had increased levels of venlafaxine and reduced levels of O-desmethylvenlafaxine compared to people with normal CYP2D6 ("extensive metabolizers"). The differences between the CYP2D6 poor and extensive metabolizers, however, are not expected to be clinically important because the sum of venlafaxine and O-desmethylvenlafaxine is similar in the two groups and venlafaxine and O-desmethylvenlafaxine are pharmacologically approximately equiactive and equipotent.

代谢
抑郁症药物文拉法辛(VF)在体外研究中被转化为其主要两种代谢物:O-去甲基文拉法辛(ODV)和N-去甲基文拉法辛(NDV),使用人肝微粒体和含有单个人类细胞色素P450(CYP)的微粒体进行。文拉法辛与选择性CYP抑制剂和几种选择性5-羟色胺再摄取抑制剂(SSRIs)共同培养,以评估它们对文拉法辛代谢的抑制效果。与人微粒体共同培养的ODV形成速率符合单一酶介导反应的米氏动力学,并受到底物抑制。通过非线性回归确定的平均参数为:Vmax = 0.36 nmol/min/mg蛋白质,Km = 41微M,Ks = 22901微M(Ks代表一个常数,反映了底物抑制的程度)。奎尼丁(QUI)是ODV形成的强效抑制剂,其Ki为0.04微M,帕罗西汀(PX)是最有效的SSRI抑制剂,其平均Ki值为0.17微M。使用表达的细胞色素的研究表明,ODV由CYP2C9、-2C19和-2D6形成。CYP2D6占主导地位,具有最低的Km,23.2微M,以及最高的内在清除率(Vmax/Km比率)。对于所有四个测试的肝脏,没有独特的模型适用于NDV的形成。应用单一酶模型确定的参数为Vmax = 2.14 nmol/min/mg蛋白质,Km = 2504微M。酮康唑是NDV生成的强效抑制剂,尽管其抑制活性不如纯3A底物观察到的强。NDV形成也受到针对大鼠肝CYP3A1的多克隆兔抗体的42%抑制。使用表达的细胞色素的研究表明,NDV由CYP2C9、-2C19和-3A4形成。最高的内在清除率归因于CYP2C19,最低的归因于CYP3A4。然而,3A亚型的高体内丰度将放大这一细胞色素的重要性。伏沙明(FX)在20微M的浓度下,将NDV的产生降低了46%,这与FX抑制CYP3A、2C9和2C19的能力一致。这些结果与先前的研究一致,表明CYP2D6和-3A4在ODV和NDV的形成中发挥着重要作用。此外,我们还展示了其他几种CYP在文拉法辛生物转化中发挥着重要作用。
The biotransformation of venlafaxine (VF) into its two major metabolites, O-desmethylvenlafaxine (ODV) and N-desmethylvenlafaxine (NDV) was studied in vitro with human liver microsomes and with microsomes containing individual human cytochromes from cDNA-transfected human lymphoblastoid cells. VF was coincubated with selective cytochrome P450 (CYP) inhibitors and several selective serotonin reuptake inhibitors (SSRIs) to assess their inhibitory effect on VF metabolism. Formation rates for ODV incubated with human microsomes were consistent with Michaelis-Menten kinetics for a single-enzyme mediated reaction with substrate inhibition. Mean parameters determined by non-linear regression were: Vmax = 0.36 nmol/min/mg protein, K(m) = 41 microM, and Ks 22901 microM (Ks represents a constant which reflects the degree of substrate inhibition). Quinidine (QUI) was a potent inhibitor of ODV formation with a Ki of 0.04 microM, and paroxetine (PX) was the most potent SSRI at inhibiting ODV formation with a mean Ki value of 0.17 microM. Studies using expressed cytochromes showed that ODV was formed by CYP2C9, -2C19, and -2D6. CYP2D6 was dominant with the lowest K(m), 23.2 microM, and highest intrinsic clearance (Vmax/K(m) ratio). No unique model was applicable to the formation of NDV for all four livers tested. Parameters determined by applying a single-enzyme model were Vmax = 2.14 nmol/min/mg protein, and K(m) = 2504 microM. Ketoconazole was a potent inhibitor of NDV production, although its inhibitory activity was not as great as observed with pure 3A substrates. NDV formation was also reduced by 42% by a polyclonal rabbit antibody against rat liver CYP3A1. Studies using expressed cytochromes showed that NDV was formed by CYP2C9, -2C19, and -3A4. The highest intrinsic clearance was attributable to CYP2C19 and the lowest to CYP3A4. However the high in vivo abundance of 3A isoforms will magnify the importance of this cytochrome. Fluvoxamine (FX), at a concentration of 20 microM, decreased NDV production by 46% consistent with the capacity of FX to inhibit CYP3A, 2C9, and 2C19. These results are consistent with previous studies that show CYP2D6 and -3A4 play important roles in the formation of ODV and NDV, respectively. In addition we have shown that several other CYPs have important roles in the biotransformation of VF.

代谢
在此案例报告中,一名被表型和基因型识别为广泛代谢型CYP2D6的患者在服用450毫克/天的文拉法辛和多种合并用药的情况下,三次测量到了异常高的文拉法辛血浆浓度。在第一次血样中,文拉法辛和O-去甲基文拉法辛的值分别确定为1.54和0.60毫克/升,这给出了一个异常高的文拉法辛到O-去甲基文拉法辛的比例。这表明文拉法辛到O-去甲基文拉法辛的代谢受损,最可能是由于米安色林(240毫克/天)和普萘洛尔(40毫克/天)的代谢相互作用。在此血样中测量的(S)-文拉法辛浓度几乎是(R)-文拉法辛的两倍((S)/(R)比例:1.94)。在第二次采血时,加入了强有力的CYP2D6抑制剂硫利达嗪(260毫克/天),文拉法辛的浓度进一步增加(2.76毫克/升),而O-去甲基文拉法辛的浓度降低(0.22毫克/升)。(S)/(R)-文拉法辛比例的降低(-20%)表明在这些高文拉法辛浓度下,参与文拉法辛O-去甲基化的酶可能对(R)-对映体具有立体选择性。在第三次采血时,中断了硫利达嗪治疗后,文拉法辛和O-去甲基文拉法辛的浓度与第一次血样中测量的相似。这个病例报告显示了进行关于遗传决定或获得的代谢缺陷对文拉法辛动力学影响的研究的重要性。
On three occasions, unusually high trough plasma concentrations of venlafaxine were measured in a patient phenotyped and genotyped as being an extensive CYP2D6 metabolizer and receiving 450 mg/day of venlafaxine and multiple comedications. Values of 1.54 and of 0.60 mg/l of venlafaxine and O-desmethylvenlafaxine, respectively, were determined in the first blood sample, giving an unusually high venlafaxine to O-desmethylvenlafaxine ratio. This suggests an impaired metabolism of venlafaxine to O-desmethylvenlafaxine, and is most likely due to metabolic interactions with mianserin (240 mg/day) and propranolol (40 mg/day). Concentration of (S)-venlafaxine measured in this blood sample was almost twice as high as (R)-venlafaxine ((S)/(R) ratio: 1.94). At the second blood sampling, after addition of thioridazine (260 mg/day), which is a strong CYP2D6 inhibitor, concentrations of venlafaxine were further increased (2.76 mg/l), and concentrations of O-desmethylvenlafaxine decreased (0.22 mg/l). A decrease of the (S)/(R)-venlafaxine ratio (-20%) suggests a possible stereoselectivity towards the (R)-enantiomer of the enzyme(s) involved in venlafaxine O-demethylation at these high venlafaxine concentrations. At the third blood sampling, after interruption of thioridazine, concentrations of venlafaxine and O-desmethylvenlafaxine were similar to those measured in the first blood sample. This case report shows the importance of performing studies on the effects of either genetically determined or acquired deficiency of metabolism on the kinetics of venlafaxine.

毒理性
  • 毒性总结
盐酸文拉法辛的准确作用机制尚不清楚,但似乎与其在中枢神经系统中增强神经递质活性的作用有关。盐酸文拉法辛及其活性代谢物O-去甲文拉法辛(ODV)可抑制5-HT和NE的再摄取,对5-HT再摄取过程的抑制效力大于NE再摄取过程。文拉法辛和ODV代谢物对多巴胺的再摄取有轻微的抑制作用,但与三环类抗抑郁药不同,且与SSRIs相似,它们在组胺能、毒蕈碱能或α1-肾上腺素能受体上无活性。
The exact mechanism of action of venlafaxine is unknown, but appears to be associated with the its potentiation of neurotrasmitter activity in the CNS. Venlafaxine and its active metabolite, O-desmethylvenlafaxine (ODV), inhibit the reuptake of both serotonin and norepinephrine with a potency greater for the 5-HT than for the NE reuptake process. Both venlafaxine and the ODV metabolite have weak inhibitory effects on the reuptake of dopamine but, unlike the tricyclics and similar to SSRIs, they are not active at histaminergic, muscarinic, or alpha(1)-adrenergic receptors.

  • 肝毒性
肝脏测试异常在接受文拉法辛或去甲文拉法辛治疗的患者中报告的发生率不到1%,而且升高的程度通常较轻,通常不需要调整剂量或停药。在接受文拉法辛治疗的患者中,但未在去甲文拉法辛治疗的患者中报告了急性、临床上明显的肝脏损伤的罕见病例,表现为肝酶显著升高,伴或不伴黄疸,这可能是由于对较新批准的药物使用较少。损伤的发生通常在1到3个月内。血清酶升高的模式从胆汁淤积到肝细胞不等。所有病例都是自限性的,并在几个月内解决。自身免疫(自身抗体)和免疫过敏特征(皮疹、发热、嗜酸性粒细胞增多)不常见或轻微。估计的发生频率为每5000名患者暴露一年中有1例。 可能性评分(文拉法辛):B(很可能是临床上明显肝脏损伤的罕见原因)。 可能性评分(去甲文拉法辛):E*(怀疑但未证实的临床上明显肝脏损伤的原因)。
Liver test abnormalities have been reported to occur in less than 1% of patients on venlafaxine or desvenlafaxine, and elevations are usually modest and usually do not require dose modification or discontinuation. Rare instances of acute, clinically apparent episodes of liver injury with marked liver enzyme elevations with or without jaundice have been reported in patients on both venlafaxine but not desvenlafaxine, perhaps because of less overall use of the more recently approved agent. The onset of injury is usually within 1 to 3 months. The patterns of serum enzyme elevation have varied from cholestatic to hepatocellular. All cases have been self-limiting and resolved within a few months. Autoimmune (autoantibodies) and immunoallergic features (rash, fever, eosinophilia) are uncommon or mild. The estimated frequency is 1 per 5000 patients years of exposure. Likelihood score (venlafaxine): B (highly likely rare causes of clinically apparent liver injury). Likelihood score (desvenlafaxine): E* (suspected but unproven cause of clinically apparent liver injury).

口服给药后,文拉法辛被很好地吸收,绝对生物利用度大约为45%。在质量平衡研究中,至少有92%的单次口服剂量的文拉法辛被吸收。在每日两次口服150毫克文拉法辛即释制剂后,Cmax(最高血药浓度)为150 ng/mL,Tmax(达到最高血药浓度的时间)为5.5小时。ODV(活性代谢物O-去甲基文拉法辛)的Cmax和Tmax分别为260 ng/mL和9小时。文拉法辛的缓释制剂吸收速率较慢,但吸收程度与即释制剂相同。在每日一次口服75毫克文拉法辛缓释制剂后,Cmax为225 ng/mL,Tmax为2小时。ODV的Cmax和Tmax分别为290 ng/mL和3小时。食物不影响文拉法辛或其活性代谢物ODV的生物利用度。
Venlafaxine is well absorbed after oral administration with an absolute bioavailability of approximately 45%. In mass balance studies, at least 92% of a single oral dose of venlafaxine was absorbed. After twice-daily oral administration of immediate-release formulation of 150 mg venlafaxine, Cmax was 150 ng/mL and Tmax was 5.5 hours. Cmax and Tmax of ODV were 260 ng/mL and nine hours, respectively. The extended-release formulation of venlafaxine has a slower rate of absorption, but the same extent of absorption as the immediate-release formulation. After once-daily administration of extended-release formulation of 75 mg venlafaxine, Cmax was 225 ng/mL and Tmax was two hours. Cmax and Tmax of ODV were 290 ng/mL and three hours, respectively. Food does not affect the bioavailability of venlafaxine or its active metabolite, O-desmethylvenlafaxine (ODV).
