BACKGROUND Herbs usually contain a mixture of biologically active constituents, which can interact with numerous prescribed drugs and alter their safety profiles. OBJECTIVES The current investigation was aimed to evaluate the effect of commonly used herbal products including black seed (Nigella sativa), garden cress (Lepidium sativum), and fenugreek (Trigonella foenum-graecum) on the pharmacokinetics and pharmacodynamics of clopidogrel using a Wistar rat model. METHODS A GC-MS analysis revealed the presence of several phytoconstitutents (polyphenols) in the extracts of black seed, garden cress, and fenugreek. These polyphenols have the potential to interfere with clopidogrel effect. Plasma concentrations of clopidogrel were measured at different time points in the absence and presence of the concurrent use of tested herbal products and the pharmacokinetic parameters were calculated. Bleeding time was measured in various groups as a measure of the antiplatelet effect of clopidogrel. RESULTS Area under the plasma concentration-time curves (AUC0-∞) of clopidogrel were 35.53 ±0.89 μg/ml*h (p<0.05), 26.01 ±0.90 μg/ml*h (p>0.05) and 32.80 ±2.51 μg/ml*h (p<0.05) in the black seed, garden cress and fenugreek group, respectively, compared with that of the control group (27.02 ±0.42 μg/ml*h). Treatment with black seed also caused an increase in clopidogrel Cmax by 31.52% (p<0.05) and with fenugreek by 21.42% (p<0.05); Cmax, did not changed with garden cress treatment (6.48 ±0.15 μg/ml versus 6.12 ±0.21 μg/ml, p>0.05). The pharmacodynamic evaluation of the antiplatelet effect of clopidogrel in the presence of herbal products treatment showed a significant prolongation in the bleeding time from a control baseline by ~22-26%, and by added ~8-12% in reference to clopidogrel therapeutic effect (p<0.05). CONCLUSION The concurrent use of black seed, fenugreek, or garden cress can alter the pharmacokinetics and pharmacodynamics of clopidogrel to varying degrees due to the presence of various bioactive polyphenols. This is probably due to changes in drug disposition and its antiplatelet action. Further confirmation can determine the clinical relevance of these observations and identify the exact constituents responsible for such activities.

氯吡格雷-草药相互作用:大鼠模型中的药代动力学和药效学评估。

背景技术草药通常含有生物活性成分的混合物,它们可以与许多处方药相互作用并改变它们的安全性。目的 本研究旨在使用 Wistar 大鼠模型评估常用草药产品,包括黑种子 (Nigella sativa)、水芹 (Lepidium sativum) 和胡芦巴 (Trigonella foenum-graecum) 对氯吡格雷药代动力学和药效学的影响。 . 方法 GC-MS 分析显示在黑种子、水芹和胡芦巴的提取物中存在几种植物成分(多酚)。这些多酚有可能干扰氯吡格雷的作用。在不存在和同时使用受试草药产品的情况下,在不同时间点测量氯吡格雷的血浆浓度,并计算药代动力学参数。在各组中测量出血时间,作为氯吡格雷抗血小板作用的量度。结果氯吡格雷血药浓度-时间曲线下面积(AUC0-∞)分别为35.53 ±0.89 μg/ml*h(p<0.05)、26.01 ±0.90 μg/ml*h(p>0.05)和32.80 ±2.51 μg/与对照组(27.02 ±0.42 μg/ml*h)相比,黑籽、水芹和胡芦巴组的ml*h(p<0.05)。黑种子处理也导致氯吡格雷 Cmax 增加 31.52%(p<0.05),胡芦巴增加 21.42%(p<0.05);Cmax 不因水芹处理而改变(6.48 ±0.15 μg/ml 对比 6.12 ±0.21 μg/ml,p>0。05)。氯吡格雷抗血小板作用的药效学评估显示,与对照基线相比,出血时间显着延长约 22-26%,与氯吡格雷治疗效果相比增加约 8-12%。 p<0.05)。结论 由于存在多种生物活性多酚,黑籽、胡芦巴或水芹的同时使用可以不同程度地改变氯吡格雷的药代动力学和药效学。这可能是由于药物配置及其抗血小板作用的变化。进一步确认可以确定这些观察结果的临床相关性并确定负责此类活动的确切成分。在存在草药产品治疗的情况下氯吡格雷抗血小板作用的药效学评估显示出血时间比对照基线显着延长约 22-26%,与氯吡格雷治疗效果相比增加约 8-12%。 p<0.05)。结论 由于存在多种生物活性多酚,黑籽、胡芦巴或水芹的同时使用可以不同程度地改变氯吡格雷的药代动力学和药效学。这可能是由于药物配置及其抗血小板作用的变化。进一步确认可以确定这些观察结果的临床相关性并确定负责此类活动的确切成分。氯吡格雷抗血小板作用的药效学评估显示,与对照基线相比,出血时间显着延长约 22-26%,与氯吡格雷治疗效果相比增加约 8-12%。 p<0.05)。结论 由于存在多种生物活性多酚,黑籽、胡芦巴或水芹的同时使用可以不同程度地改变氯吡格雷的药代动力学和药效学。这可能是由于药物配置及其抗血小板作用的变化。进一步确认可以确定这些观察结果的临床相关性并确定负责此类活动的确切成分。并在氯吡格雷治疗效果方面增加约 8-12% (p<0.05)。结论 由于存在多种生物活性多酚,黑籽、胡芦巴或水芹的同时使用可以不同程度地改变氯吡格雷的药代动力学和药效学。这可能是由于药物配置及其抗血小板作用的变化。进一步确认可以确定这些观察结果的临床相关性并确定负责此类活动的确切成分。并在氯吡格雷治疗效果方面增加约 8-12% (p<0.05)。结论 由于存在多种生物活性多酚,黑籽、胡芦巴或水芹的同时使用可以不同程度地改变氯吡格雷的药代动力学和药效学。这可能是由于药物配置及其抗血小板作用的变化。进一步确认可以确定这些观察结果的临床相关性并确定负责此类活动的确切成分。
