Abstract
Six out of 7 Finnish patients suffering from hereditary angioneurotic edema were helped during attacks, by treatment with tranexamic acid (AMCA, Cyklokapron, Kabi) in doses of 1.5 g 3 times daily, follow-up time 3-25 months. 3 of these patients also had continuous AMCA treatment, in the course of which 2 remained nearly symptom-free on a dosage of 1 g 2-3 times daily. Even the third one had shorter and milder attacks. One patient, however, had to stop taking AMCA after 6 weeks' treatment, because of fatigue and nausea. Follow-up time for the others was 9-11 months. For comparative purposes, 3 patients were given continuous treatment with an antihistamine, cinnarizine in a dosage of 20-30 mg daily. Two of the patients were helped by it, one becoming nearly symptom-free and the other having fewer and milder attacks; follow-up time 9-10 months.
