Summary
A double-blind cross-over study of the prophylactic value of tranexamic acid (“Cyklokapron”),
in a dose of 3.0 g per day, against spontaneous bleeding episodes in severe haemophilia
was undertaken. Records of bleeding episodes were maintained during therapy in twenty
boys with confirmed clinical severity, over two school terms. A significant reduction
(p <0.05) in spontaneous bleeding episodes was attained with an associated lessening
in the transfusion requirement of therapeutic material, and without obvious side effects.
Recommendations are made for further investigations.
