Study Notes

Classification and Dosage

Tranexamic acid is an antifibrinolytic medication.
The recommended dosage of tranexamic acid for individuals over 16 years old is 1-1.5 grams, taken orally three times a day.

Mechanism of Action

The primary action of tranexamic acid is to inhibit the breakdown of blood clots, thereby reducing bleeding.

Clinical Uses

Tranexamic acid is most useful in scenarios where there is a high risk of bleeding, such as in surgical procedures or in cases of hereditary bleeding disorders.
The indications for administering tranexamic acid include treatment of heavy menstrual bleeding, dental procedures in patients with hereditary bleeding disorders, and reduction of bleeding during and after surgery.
