Aminocaproates are pharmaceutical compounds that contain an amino group (-NH2) and a carboxylic acid group (-COOH), with a carbon atom in between. The most common representative is ethylaminoacaproic acid (EACA), which is a synthetic lysine analogue. It is used as a hemostatic agent to reduce or stop bleeding in various medical conditions, such as hemophilia or following surgical procedures. Aminocaproates work by inhibiting the conversion of plasminogen to plasmin, an enzyme that breaks down blood clots. This results in a stabilization of existing clots and a reduction in further bleeding.
