摘 要 目的:分析利福霉素类抗结核药与降压药之间的相互作用,促进临床合理用药。方法:通过分析1例肺结核合并高血压患者在抗结核治疗过程中血压控制不佳的原因及药学监护,探讨利福霉素类药物与降压药发生之间的相互作用。结果:利福喷丁可通过诱导CYP3A4的活性,加快钙通道阻滞剂的代谢,降低治疗效果,从而引起血压升高。结论:抗结核治疗过程中应重视利福霉素类药物与基础病治疗药物的相互作用问题,及时发现并适当处理,以优化药物治疗方案。

ABSTRACT Objective: To analyze rifapentine-antihypertensive interaction and promote clinical rational drug use. Methods: The mechanism of rifapentine-antihypertensive interaction was explored by analysis of the cause of poor blood pressure control in a patient with hypertension and pulmonary tuberculosis during anti-tuberculosis treatment and pharmaceutical monitoring. Results: Rifapentine could accelerate the metabolism of calcium channel blockers by inducing the activity of CYP3A4, reduce the therapeutic effect and cause poor blood pressure control. Conclusion: Attention should be paid to the interaction between rifamycin drugs and the treatment drugs for underlying diseases in the process of anti-tuberculosis treatment and timely detection and proper treatment are required to optimize the drug treatment regimen.

作為抗结核治疗一线用药利福平/利福喷丁/利福布丁属利福霉素类药物是一种经典的细胞色素P450(CYP)和P-糖蛋白(P-glycoprotein,P-gp)诱导剂[1],对CYP3A4的诱导作用最强[2-4],可使通过该酶代谢的药物或P-gp底物代谢加速,血药浓度明显降低,从而降低治疗效果。本研究介绍一例疑似肺结核且合并高血压的患者,在诊断性抗结核过程中出现血压波动的病例,分析血压波动的原因,发现利福喷丁诱导钙通道阻滞剂代谢,降低其血药浓度,导致血压控制不佳。通过探讨如何解决因药物相互作用导致的药物治疗矛盾,以期为此类患者的临床治疗提供参考。
