Tranexamic acid (commonly marketed as Cyklokapron in the US and as Transamin in Asia) is often prescribed for excessive bleeding. It is an antifibrinolytic that competitively inhibits the activation of plasminogen to plasmin, a molecule responsible for the degradation of fibrin. Fibrin is the basic framework for the formation of a blood clot in hemostasis. It has roughly 8 times the antifibrinolytic activity of an older analogue, ε-aminoacaproic acid.

[edit] Menstrual bleeding

Tranexamic acid is commonly used to treat certain types of excessive menstrual bleeding, otherwise known as menorrhagia. UK studies have found that women suffering from menorrhagia often have elevated levels of tissue plasminogen activator, an enzyme responsible for the conversion of plasminogen into plasmin

[edit] Haemophilia

Tranexamic acid is also useful in the treatment of bleeding in haemophilia patients (i.e. Tooth extraction in haemophilia patients.

[edit] Angioedema

In acquired angioedema types I and II and non-histaminergic angioedema, antifibrinolytics such as tranexamic acid or ε-aminocaproic acid may be effective.
