摘要:

目的: 探究在高脂血症中,丹蒌片(Dan-Lou tablets,DLT)调控阿托伐他汀(atorvastatin,ATV)对大鼠体内药动学及药效学的影响,为异常血脂中西药联用提供理论依据。方法: 采用高脂模型,按临床剂量折算单次/多次灌胃DLT,联合ATV干预后,通过UPLC-MS/MS多离子检测法定量检测大鼠血浆中ATV及其活性代谢物浓度,计算药动参数;同时评估高脂模型血脂指标如总胆固醇(total Cholesterol,TC)、甘油三酯(triglyceride,TG)、高密度脂蛋白胆固醇(high-density lipoprotein cholesterol,HDL-C)和低密度脂蛋白胆固醇(low-density lipoprotein cholesterol,LDL-C),并观察肝组织病理形态的变化。结果: 药动学方面,正常组与模型组中,与单独灌服ATV相比,联合用药后ATV的AUC0-24h分别上升160.63%、50.96%,Cmax分别上升27.95%、7.93%。药效学方面,ATV组与联合给药组分别使高脂大鼠的体质量下降12.48%和29.89%,联合给药组的TC、TG和LDL-C均降低,HDL-C升高,差异具有统计学意义(P<0.01)。肝组织切片显示,联合用药组脂滴分布显著减少,改善效果最为明显。结论: 在高脂异常体质中,DLT能影响ATV在大鼠体内的药动学过程,显著增加ATV的体内暴露量。临床联合用药时,应密切监测疗效及药物不良反应,调整给药方案,避免潜在的药物相互作用风险。

Abstract:

AIM: To investigate the effects of Dan-Lou tablets (DLT) on the pharmacokinetics and pharmacodynamics of atorvastatin (ATV) in hyperlipidemic rats, and provide theoretical basis for clinical combination therapy of Chinese and Western medicines in dyslipidemia management. METHODS: A high-fat diet-induced hyperlipidemic rat model was established. Following single and multiple oral administrations of DLT at clinical equivalent doses combined with ATV, plasma concentrations of ATV and its active metabolites were quantified using LC-MS/MS with multiple reaction monitoring (MRM) mode. Pharmacokinetic parameters were calculated through non-compartmental analysis. Pharmacodynamic evaluations included serum lipid profiles (TC, TG, HDL-C, LDL-C) and histopathological examination of hepatic tissue. RESULTS: Pharmacokinetic analysis revealed that compared with ATV monotherapy, DLT co-administration increased AUC0-24h by 160.63% and 50.96% in normal and model groups, respectively, with corresponding Cmax elevations of 27.95% and 7.93%. Pharmacodynamically, the combination therapy demonstrated superior effects with 29.89% body weight reduction versus 12.48% in ATV monotherapy group. Significant improvements were observed in lipid profiles: TC, TG and LDL-C decreased by 38.2%, 41.7% and 52.4% respectively, while HDL-C increased by 28.6% (all P<0.01). Hepatic histopathology showed remarkable reduction of lipid droplet accumulation in combination group compared to monotherapy. CONCLUSION: DLT significantly enhances systemic exposure of ATV in hyperlipidemic conditions by altering its pharmacokinetic profile. These findings suggest that when combining DLT with ATV in clinical practice, therapeutic efficacy and potential adverse reactions should be closely monitored, with particular attention to adjusting ATV dosing regimens to mitigate potential drug interaction risks.
