Mechanism of Action
Aminocaproic acid inhibits both the activity of plasminogen activators and to a lesser degree, plasmin activity by binding to lysine-binding sites within the plasminogen/plasmin molecule, which interferes with the ability of plasmin to lyse fibrin clots.
When should I take aminocaproic acid?

Is aminocaproic acid same as tranexamic acid?
Tranexamic acid (TXA) and epsilon-aminocaproic acid (EACA) belong to the lysine analog class of antifibrinolytic agents. They have similar mechanisms of action, with TXA demonstrating a 6- to 10-fold increased affinity in binding plasminogen compared with EACA.

What is the structure of aminocaproic acid?
Aminocaproic acid (also known as ε-aminocaproic acid, ε-Ahx, or 6-aminohexanoic acid) is a derivative and analogue of the amino acid lysine, which makes it an effective inhibitor for enzymes that bind that particular residue.
When should nimodipine be given?

Does fibrinolysis cause bleeding?
Primary fibrinolysis refers to the normal breakdown of clots. Secondary fibrinolysis is the breakdown of blood clots due to a medical disorder, medicine, or other cause. This may cause severe bleeding.
Can tranexamic acid cause bradycardia?
