Description: Antithrombotic agents are pharmaceuticals that prevent pathological blood clot formation through distinct mechanisms: DOACs (Factor Xa/thrombin inhibition), heparins (enhance antithrombin III), and antiplatelets (block ADP/P2Y12 receptors). They are critical for managing atrial fibrillation (stroke risk reduction by 60-70%), post-stent thrombosis, and DVT/PE. Novel agents like dabigatran (DOAC) offer fixed dosing without routine monitoring, while heparin derivatives require anti-Factor Xa activity assays.
