代谢
多非利特是一种三类抗心律失常药物,它通过肾脏和代谢途径进行清除。体外研究其代谢过程可以解释物种间的差异,而识别涉及的人类酶则允许评估潜在的药物相互作用。在肝微粒体中,多非利特氧化代谢的速率顺序为:雄性大鼠 > 雌性大鼠 > 狗 > 人,这与体内观察到的代谢清除情况相关。体外氧化代谢产物,通过N-脱烷基化形成,与体内形成的相同,其中N-去甲基是主要产物。这条多非利特代谢途径由细胞色素P450(CYP)介导。在人类中,N-脱甲基的KM值很高,为657 +/- 116 uM,表明对酶活性位点的亲和力较低。在许多人类肝微粒体制备中,这一速率与CYP3A4的活性相关(r = 0.903)。与其他同种酶的活性没有相关性。特定的同种酶抑制剂也表明CYP3A4的参与,酮康唑和托拉伦多霉素部分抑制,而激活剂α-萘黄酮导致周转增加。其他同种酶的特异性抑制剂或竞争性底物没有观察到抑制。多非利特在体外浓度高达100微M时,并未显著抑制CYP2C9、CYP2D6或CYP3A4。相比之下,胺碘酮(IC50,25 uM)和氟卡尼(49微M)抑制CYP2C9,奎尼丁(0.26 uM)和氟卡尼(0.44 uM)抑制CYP2D6。许多抗心律失常药物具有活性的循环代谢物,这使剂量与临床反应之间的关系复杂化。体外药理学研究允许评估代谢物对药理学特征的潜在贡献。比较了多非利特及其代谢物的活性,针对三类(K+通道阻断)和一类(Na+通道阻断)抗心律失常活性。多非利特的三个代谢物表现出三类活性,但浓度至少比多非利特高20倍。多非利特N-氧化物表现出一类活性,但仅在较高浓度下。任何代谢物都不会影响静息膜电位或动作电位幅度。这种生物学上不相关的活性与多非利特血浆浓度与药理反应之间的密切相关性一致。
Dofetilide, a class III antidysrhythmic agent, undergoes both renal and metabolic clearance. Characterization of the metabolism in vitro allows explanation of species differences, whereas identification of the human enzymes involved permits assessment of potential drug interaction. In liver microsomes, the rate of oxidative metabolism of dofetilide is in the order: male rat > female rat > dog > humans, which correlates with the metabolic clearance seen in vivo. In vitro products of oxidative metabolism, formed by N-dealkylation, are the same as those formed in vivo, with the N-desmethyl being the major product. This route of dofetilide metabolism is mediated by cytochrome P450 (CYP). In humans, N-demethylation has a high KM of 657 +/- 116 uM, indicating low affinity for the enzyme's active site. In a number of human liver microsomal preparations, this rate correlated (r = 0.903) with the activity of CYP3A4. There was no correlation with the activities of other isozymes. Specific isozyme inhibitors also indicated the involvement of CYP3A4, with partial inhibition being observed with ketoconazole and troleandeomycin, whereas the activator, alpha-naphthaflavone, caused increased turnover. No inhibition was observed with specific inhibitors or competing substrates for other isozymes. Dofetilide did not significantly inhibit CYP2C9, CYP2D6, or CYP3A4 at concentrations up to 100 microM in vitro. In contrast, amiodarone (IC50, 25 uM) and flecainide (49 microM) inhibited CYP2C9 and quinidine (0.26 uM), and flecainide (0.44 uM) inhibited CYP2D6. Many antidysrhythmic drugs have active, circulating metabolites, complicating the relationship of dose and clinical response. In vitro pharmacology studies allow assessment of the potential contribution to the pharmacological profile by metabolites. Potency of dofetilide and metabolites has been compared for class III (K+ channel blockade) and class I (Na+ channel blockade) antidysrhythmic activities. Three of the metabolites of dofetilide displayed class III activity but at concentrations at least 20-fold higher than dofetilide. Dofetilide N-oxide showed class I activity, but only at high concentration. Neither resting membrane potential or action potential amplitude were affected by any metabolite. This lack of biologically relevant activity is in accord with the close correlation between plasma concentrations of dofetilide and pharmacological response.

代谢
大约80%的单剂量多非利特通过尿液排出,其中大约80%以未改变的多非利特形式排出,其余20%由无活性或微活性的代谢物组成。体外研究显示,多非利特可以被CYP3A4代谢,但它对这个同工酶的亲和力较低。代谢物通过N-脱烷基化和N-氧化形成。在血浆中没有可量化代谢物,但在尿液中已经鉴定出5种代谢物。
Approximately 80% of a single dose of dofetilide is excreted in urine, of which approximately 80% is excreted as unchanged dofetilide with the remaining 20% consisting of inactive or minimally active metabolites. ... In vitro studies with human liver microsomes show that dofetilide can be metabolized by CYP3A4, but it has a low affinity for this isoenzyme. Metabolites are formed by N-dealkylation and N-oxidation. There are no quantifiable metabolites circulating in plasma, but 5 metabolites have been identified in urine

毒理性
  • 肝毒性
在临床试验中,多非利特治疗期间血清基转移酶和碱性磷酸酶的升高并不比安慰剂治疗更常见。15%的多非利特接受者报告了不同程度的ALT升高,但相似比例的安慰剂接受者也有报告;这些升高超过正常上限3倍的比例为1.5%对2.0%。因此,适合接受多非利特治疗的房颤患者的血清ALT升高背景率似乎较高。尽管如此,多非利特并未与具有症状或黄疸的临床明显肝损伤的病例相关联。多非利特的产品标签没有提到肝毒性,也没有特别推荐监测肝功能测试。
In clinical trials, serum aminotransferase and alkaline phosphatase elevations were no more common during dofetilide than placebo therapy. Some degree of ALT elevation was reported in 15% of dofetilide but a similar proportion of placebo recipients; these elevations were above 3 times the upper limit of normal in 1.5% vs 2.0%. Thus, the background rate of serum ALT elevations in patients with atrial fibrillation eligible for dofetilide treatment appears to be high. Despite this, dofetilide has not been linked to instances of clinically apparent liver injury with symptoms or jaundice. The product label for dofetilide does not mention hepatotoxicity and does not specifically recommend monitoring of liver tests.

吸收、分配和排泄
1. 对 dofetilide 的药物动力学进行了研究,涉及人类、狗、大鼠和小鼠,在单次静脉注射和口服 dofetilide 或 (14)C-dofetilide 剂量后。2. dofetilide 在所有物种中都被完全吸收。人类较低的代谢清除率导致口服给药后完全的生物利用度。啮齿类动物和狗(程度较小)较高的代谢清除率导致生物利用度降低,这是由于首次通过肝脏代谢。3. 静脉给药后,分布体积在所有物种中只有适度的变化(2.8-6.3 l/kg)。啮齿类动物高血浆清除率导致短的半衰期值(小鼠 0.32 小时,雄性大鼠 0.5 小时,雌性大鼠 1.2 小时),而狗和人类较低的清除率导致更长的末端消除半衰期(分别为 4.6 小时和 7.6 小时)。4. 单次静脉注射 (14)C-dofetilide 剂量后,未改变的药物是所有物种尿液中排出的主要成分,同时还存在几种代谢物。5. 在所有物种尿液中鉴定出的代谢物是由 dofetilide 三级氮原子的 N-氧化或 N-脱烷基化形成的。6. 在人类口服和静脉给药 (14)C-dofetilide 后,母化合物是血浆中唯一可检测到的成分,占血浆放射活性的 75%。没有单一的代谢物占血浆放射活性的 5% 以上。
1. Pharmacokinetics of dofetilide were studied in man, dog, rat and mouse after single IV and oral doses of dofetilide or (14)C-dofetilide. 2. Dofetilide was absorbed completely in all species. Low metabolic clearance in man resulted in complete bioavailability following oral administration. Higher metabolic clearance in rodents, and to a lesser extent dogs, resulted in decreased bioavailability because of first-pass metabolism. 3. Following IV administration, the volume of distribution showed only moderate variation in all species (2.8-6.3 l/kg). High plasma clearance in rodents resulted in short half-life values (mouse 0.32, male rat 0.5 and female rat 1.2 hr), while lower clearance in dog and man gave longer terminal elimination half-lives (4.6 and 7.6 hr respectively). 4. After single IV doses of (14)C-dofetilide, unchanged drug was the major component excreted in urine of all species with several metabolites also present. 5. Metabolites identified in urine from all species were formed by N-oxidation or N-dealkylation of the tertiary nitrogen atom of dofetilide. 6. After oral and IV administration of (14)C-dofetilide to man, parent compound was the only detectable component present in plasma and represented 75% of plasma radioactivity. No single metabolite accounted for greater than 5% of plasma radioactivity.
