Pharmacology
C1-esterase inhibitor (C1-INH) is a serine protease inhibitor (serpin) that inactivates key proteases in the complement, fibrinolytic, and coagulation systems -- including C1r, C1s, factor XIIa, and plasma kallikrein -- thereby preventing bradykinin generation and reducing vascular permeability; HAEGARDA replaces the missing or malfunctioning C1-INH protein in HAE patients.
Bradykinin B2 receptor antagonist; icatibant competitively inhibits bradykinin from binding the B2 receptor, blocking the vasodilation, inflammation, and pain associated with bradykinin release in acute HAE attacks caused by C1-esterase-inhibitor deficiency or dysfunction.
