QUICK LINKS

Tranexamic acid is a derivative of the amino acid lysine. Tranexamic acid functions as an antifibrinolytic agent by inhibiting the activation of plasminogen to plasmin, which in turn prevents the degradation of fibrin clots. This makes it effective in reducing bleeding by stabilizing blood clots and preventing their breakdown.
