Aminocaproic acid or tranexamic acid is described as having which role?

• A. In fibrinolytic reversal
• B. Used prophylactically before procedures
• C. Treat bleeding during surgery
• D. Not used

Answer: (A)

Aminocaproic acid and tranexamic acid are antifibrinolytics that prevent the breakdown of clots by inhibiting the activation of plasminogen to plasmin. Because they directly counteract fibrinolysis, their primary clinical role is to reverse excessive fibrinolysis or bleeding caused by thrombolytic therapy. In practice, they are used to stop or reduce bleeding when plasmin is driving the loss of clot stability, such as after administration of thrombolytics or in hyperfibrinolytic states. While they can help reduce bleeding around certain procedures in some contexts, the best description of their main role is reversing fibrinolysis.
