  • Clinical Efficacy
    • Systematic Review of Anti-Fibrinolytics in Acute Trauma (Cochrane Database Syst Rev, 2015) [MEDLINE]
      • Tranexamic Acid Decreased Mortality Rate in Trauma with Hemorrhage without Increasing the Risk of Adverse Effects
      • Tranexamic Acid Should Be GIven within 3 hrs of Injury: treatment later than 3 hrs is likely to be ineffective or harmful (data from CRASH-2 Trial)
      • Unclear if Tranexamic Acid Has Efficacy in Traumatic Brain Injury (TIB) (see Traumatic Brain Injury, [[Traumatic Brain Injury]])


  • Anti-Fibrinolytic (see Anti-Fibrinolytics, [[Anti-Fibrinolytics]]): lysine analogue which binds to kringle domains of plasminogen, disrupting interaction between plasminogen (and plasmin) and lysine residues within fibrin
    • Epsilon Aminocaproic Acid (see Epsilon Aminocaproic Acid, [[Epsilon Aminocaproic Acid]]): binds plasminogen (and plasmin) 1/8 as avidly as tranexamic acid -> may exert a less potent anti-hemorrhagic effect
