Tranexamic acid for control of haemorrhage in acute promyelocytic leukaemia

Abstract

In a double-blind study, 12 consecutive patients with acute promyelocytic leukaemia were randomised either to tranexamic acid (TA group) or to placebo (control group) for 6 days to see whether inhibition of fibrinolysis would reduce haemorrhage and transfusion requirements. The total study period was 14 days. In the TA group, there were fewer haemorrhagic episodes, as determined by a scoring system. Packed red cell transfusion requirements decreased; and fewer additional platelet concentrate transfusions were needed. These beneficial effects were more pronounced in the second week. There were no thromboembolic complications.
