Which of the following is an antifibrinolytic agent?

Ans. d. Epsilon aminoeaproic acid (Ref: Goodman Gilman 12/e p867; Katzung 12/e p616; KDT 7/e p628, 6/e p608) Epsilon-aminocaproic acid is a synthetic inhibitor of the ptasmin-plasminogen system. It is the only potent antifibrinolytic agent, which is commercially available."Aminoeaproic acid is a lysine analog that competes for lysine binding sites on plasminogen and plasmin, blocking the interaction of plasmin with fibrin. Aminocaproic acid is thereby a potent inhibitor of fibrinolysis and can reverse states that are associated with excessive fibrinolysis.
