Definitions

  • the present invention relates to a medicament for inhibiting thrombus formation.
  • thrombotic diseases such as myocardial infarction and cerebral thrombosis are among the highest in various diseases.
  • Coronary artery or cerebrovascular artery stenosis and thrombosis are caused by repeated damage to blood vessels based on atherosclerosis.

  • ADP adenosine diphosphate
  • TXA 2 thromboxane A 2
  • Vascular injury also activates the coagulation system, and the resulting thrombin promotes further aggregation of platelets, which also leads to the formation of fibrin, which is stabilized by cross-linking.
  • Antiplatelet drugs can inhibit the adhesion, aggregation and release of platelets, inhibit thrombosis, and therefore play an important role in the prevention and treatment of thrombotic diseases.
  • Triflumuride antiplatelet coagulant has a more specific effect than acetylsalicylic acid (aspirin) in the prevention and treatment of thromboembolic diseases and complications. Compared with aspirin, it can simultaneously antagonize the activities of cyclooxygenase and c-AMP phosphodiesterase, and has strong anti-platelet aggregation ability, but has little effect on prostacyclin biosynthesis at therapeutic dose, and the risk of bleeding is also very high. small. Studies have shown that trifluxon and aspirin do not differ in the prevention of severe cardiovascular events in patients with peripheral arteriosclerotic occlusive disease (PA0D), but the incidence of severe bleeding complications is significantly lower than that of aspirin.
  • PA0D peripheral arteriosclerotic occlusive disease
  • Clopidogrel is also a commonly used anti-platelet aggregation drug.

Clopidogrel is generally considered to be slightly better than aspirin, but other benefits are not statistically different from aspirin, and authorities have not yet proposed a better basis for aspirin.

Description

一种抑制血栓形成的药物 技术领域
本发明涉及一种抑制血栓形成的药物。
背景技术
心肌梗塞和脑血栓等血栓性疾病的发病率、 致残率和死亡率在各种疾 病中居前列。 冠状动脉或脑血管动脉狭窄及血栓形成, 是在动脉粥样硬化 的基础上, 血管反复损伤所致。 血管损伤时, 血小板粘附于暴露的内皮下 组织, 粘附的血小板释放其颗粒中的内容物,二磷酸腺苷 (ADP)及经膜磷脂 代谢形成的血栓素 A2 (TXA2),二者激活循环中的血小板,在纤维蛋白原的参 与下, 血小板聚集成团,形成血小板血栓。 血管损伤亦激活凝血系统, 生 成的凝血酶促使血小板进一步聚集, 亦导致纤维蛋白的形成, 经交联使动 脉血栓稳固。 抗血小板药可抑制血小板的粘附、 聚集和释放功能, 阻抑血 栓形成, 因此在血栓性疾病的防治中具有重要地位。
三氟柳属抗血小板凝聚剂, 在预防和治疗血栓栓塞性疾病及并发症上 比乙酰水杨酸 (阿司匹林) 具有更特殊的效果。 与阿司匹林相比, 可同时 拮抗环氧合酶和 c-AMP磷酸二酯酶的活性, 抗血小板聚集能力强, 但在治 疗剂量时对前列环素生物合成的影响很小, 出血危险性也很小。研究表明, 三氟柳与阿司匹林在预防周围动脉硬化闭塞性疾病 (PA0D ) 患者严重心血 管事件方面无差别,但其严重出血并发症的发生率显著低于阿司匹林。
氯吡格雷也是常用的抗血小板聚集的药物,其机理是使 ADP受体 P2Y12 发生不可逆改变而选择性抑制 ADP所诱导的血小板聚集,还可抑制由胶原 和凝血酶诱导的血小板聚集。 一般认为氯吡格雷比阿司匹林效果稍好,但 其它益处与阿司匹林相比无统计学差异, 且权威人士尚未提出它较阿司匹 林更好的依据。 对于对低剂量阿司匹林有禁忌者,氯吡格雷(75mg/d)是高 危冠脉脑血管或外周血管疾患者的适宜的替代药物。
