GENERIC NAME: tranexamic acid


DRUG CLASS AND MECHANISM: Tranexamic acid promotes the clotting of blood and thereby reduces bleeding due to heavy menstruation. Tranexamic acid is a man-made amino acid derivative that increases blood clotting by preventing the breakdown of fibrin. Fibrin is a protein and an important component of blood clots. It is broken down by another protein called plasmin. Tranexamic acid blocks the action of plasmin on fibrin and thereby prevents the breakdown of fibrin. This leads to stabilization and preservation of fibrin in blood clots, and this helps reduce bleeding during a heavy menstrual cycle. The FDA approved tranexamic acid in November 2009.



PREPARATIONS: Tablets: 650 mg.

STORAGE: Tranexamic acid tablets should be stored between 15 C to 30 C (59 F to 86 F).
