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.
Plasma kallikrein inhibitor; ecallantide is a potent, selective, reversible inhibitor of plasma kallikrein that blocks its binding site, reducing the conversion of HMW kininogen to bradykinin and thereby treating symptoms during acute episodic attacks of HAE.
