一般說明

乙酰水杨酸是一种有机化合物,通常被称为阿司匹林。它通过阻止体内引发疼痛、肿胀和发热的化合物的产生来起作用。乙酰水杨酸还在预防动脉中形成血凝块方面发挥重要作用。在研究中,乙酰水杨酸被研究其在氧化应激中的作用,并在癌症研究作为生物标志物。

生化/生理作用

通过抑制环氧化酶(前列腺素H合酶),对COX-1亚型具有更高的选择性,阻止前列腺素的产生。抗血栓作用是由于COX-1在血小板中的抑制作用,阻止血栓形成和血小板聚集。 对结直肠及其他实体肿瘤有化学预防作用。

Treatment with nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with various side effects, including cardiovascular and hepatic disorders. Studies suggest that mitochondrial damage and oxidative stress are important mediators of toxicity, yet the underlying mechanisms are poorly understood. In this study

Bleeding limits anticoagulant treatment in patients with acute coronary syndromes (ACS). We investigated whether background concomitant antiplatelet therapy influences the effects of apixaban after ACS. This study examined high-risk ACS patients who were treated with aspirin or aspirin plus clopidogrel
