There are only a few studies directly comparing outcomes following the use of intravenous tranexamic acid (IVTA) and oral tranexamic acid (OTA) in arthroplasty surgery. In the randomized study by Zohar et al5. OTA (n = 20) was associated with significant allogeneic blood sparing com- pared with controls (n = 20), but not when compared with short- and long-term IVTA regimens. A recent randomized trial comparing OTA (n = 26) with placebo (n = 20) reported significant reductions in blood drained at 24 hours, and in the fall of both Hb and Hct in the OTA group, without any significant difference in the requirement of transfusion6.
