Why is it necessary to administer Transamin before surgery?

Abnormal bleeding may occur suddenly during or after operation. Although Transamin is a quick-acting medicine for abnormal bleeding, it is administered before operation to prevent the risk of bleeding beforehand. Doctors used to administer hemostatic drugs after abnormal bleeding occured, but it is an old custom whose time has passed. As preoperative therapy, Transamin is often orally administered. When oral administration is not possible, the drug is injected.
