Mode of Action
Tranexamic acid is an antifibrinolytic agent that competitively inhibits breakdown of fibrin clots. It blocks binding of plasminogen and plasmin to fibrin, thereby preventing haemostatic plug dissolution.
Precaution
Mild to moderate renal impairment, irregular menstrual bleeding, previous history of thromboembolic disease, haematuria. Monitor closely in disseminated intravascular coagulation. Monitor LFT and eye examination regularly during long-term use. Discontinue if disturbance in colour vision occurs. Avoid IV inj rate >1 ml/minute due to risk of hypotension. Pregnancy, lactation.
