What is the action of anticoagulants in patient care?

Anticoagulants play a crucial role in patient care primarily by preventing the formation of blood clots. They do this by inhibiting various factors in the coagulation cascade, which is the series of steps that lead to clot formation. By interfering with this process, anticoagulants help to reduce the risk of thromboembolism, which can occur in conditions such as atrial fibrillation, deep vein thrombosis, or after certain surgeries.

Unlike thrombolytics, which actively dissolve existing clots, anticoagulants are not designed for that purpose. They do not strengthen blood vessels or directly improve blood flow; rather, their main function is to manage and reduce the risk of new clots forming, thereby protecting patients who have a predisposition to clotting disorders or are at risk of complications from clots. This preventive action is vital in ensuring better health outcomes for patients who are susceptible to clot-related issues.
