[Therapeutic approach of hereditary angioedema].

Purpose: Hereditary Angioedema was first described by William Osler in 1888 and it is caused by a hereditary or acquired deficiency of C1 esterase inhibitor (C1-INH). Treatment is indicated for acute attacks or prophylaxis of angioedema which occur in the subcutaneous tissue respiratory or gastrointestinal tracts. Treatment includes attenuated androgens, inhibitors of kininogen or plasminogen, like tranexamic acid or e-aminocaproic acid and the administration of C1-INH concentrate.
