PCSK9抑制药的药理作用机制研究现状及临床应用探讨

Research status of pharmacological mechanism of PCSK9 inhibitors and discussion of their clinical application

由脂质代谢紊乱引起的动脉粥样硬化是动脉粥样硬化性心血管疾病的主要病理基础。他汀类药物是这类疾病调脂治疗的基石,但在实际应用中部分患者仍存在血脂管理不达标的状况。前蛋白转化酶枯草溶菌素9(PCSK9)抑制药作为一类新型调脂药物被逐渐应用于该类患者治疗,近年来的研究表明PCSK9抑制药除了能调节脂质代谢,还具有潜在的抗炎、抗血小板活化等作用。本文梳理了PCSK9抑制药多个药理作用机制及临床研究现状,探讨可能影响PCSK9抑制药疗效的因素,以期为PCSK9抑制药的安全合理用药提供参考。

Atherosclerosis caused by disorders of lipid metabolism is the main pathological basis of atherosclerotic cardiovascular disease.Statins are the cornerstone of lipid-modulating therapy for this type of disease,but in practice there are still some patients with suboptimal lipid management.Proprotein convertase subtilisin/kexin type 9(PCSK9)inhibitors have been gradually applied as a new class of lipid-modulating drugs for the treatment in patients with this type of disease,and recent studies have shown that in addition to regulating lipid metabolism,PCSK9 inhibitors also have potential anti-inflammatory and anti-platelet activation effects.This article sorts out the multiple pharmacological mechanisms of action of PCSK9 inhibitors and the current status of clinical research of PCSK9 inhibitors.Besides,it discusses the factors that may affect the efficacy of PCSK9 inhibitors,in order to provide a reference for the safe and rational medication of PCSK9 inhibitors.
