Prophylaxis of attacks of hereditary angioedema.

Abstract

Danazol, an attentuated androgen, has been suggested as an effective agent for the prophylaxis of attacks of hereditary angioedema. Four patients, with a clinical history of hereditary angioedema and a demonstrated depression of the serum inhibitor of the first component of complement (C1 INH) and the fourth component of complement (C4), were entered into a study to determine the minimum effective dose of this agent. All four of the patients had been experiencing attacks at least monthly, but they had only six attacks during a total of 60 patient months of Danazol therapy. The minimum effective dose varied from 100 to 400 mg/day. The drug appeared to work by increasing the level of serum C1 INH which reached the normal range in two of four patients. Side effects were only the anticipated menstrual irregularities in the female patients. Danazol appears to be an efficacious drug for prophylaxis of hereditary angioedema.
