Antiplatelets drugs, and in particular aspirin, have therefore been recognised as potential therapeutics for COVID-19 disease. Despite being theoretically attractive, the RECOVERY trial, the only large randomised controlled trial to date, showed no difference in mortality or progression to invasive ...

Mechanism of action; Clinical pharmacology of the antiplatelet effect... AAAAD &Mdash,NEJM - 《New England Journal of Medicine》 被引量: 168发表: 0年 In brief: enteric-coated aspirin as an antiplatelet drug Aspirin is widely used as an anti-thrombotic drug; however, it has been suggested ...
Thus a thorough understanding of the various platelet inhibitors, their mechanism of action, and their indications is paramount. The P2Y12 Receptor Thienopyridines (ticlopidine, clopidogrel, and prasugrel) bind to the extracellular nucleotide P2Y12 receptor, found on the cell surface of platelets, ...
63,65,106, 107, 108 The exact mechanisms of RNA signature in TEP are not well understood. One mechanism might be via cancer cells releasing RNA into their local environment, likely through EV such as tumor-derived exosomes,109, 110, 111 and transferring mutant RNA into platelets.63,65,107...
38 Therefore, efficacy of antithrombotic agents may vary by mechanism of action, illness severity, dose, and duration. Platelets are activated and hyperaggregable in patients with COVID-19.11,12 Activated platelets reciprocally upregulate systemic inflammation, and therefore, platelet inhibition may ...
Clopidogrel is a novel ADP-selective agent whose antiaggregating properties are several times higher than those of ticlopidine and are apparently due to the same mechanism of action (inhibition of ADP binding to its platelet receptor). This effect has been seen in various experimental animal species...
This is in accordance with the predictive function of bleeding risk in the "PRECISE-DAPT" score and also potentially elucidates the mechanism behind bleeding risks during DAPT. Controversies persist regarding the relationship between leukocyte count and the antiplatelet effect in CAD patients. A recent...
Multiple electrode aggregometry (MEA) has been shown to be a useful instrument in the quantification of platelet inhibition by ASA [6]. Its mechanism of assessing platelet inhibition is based on changes in impedance on its sensor wires secondary to platelet adherence. Aspirin resistance has been ...
