Pharmacology
Recombinant C1 esterase inhibitor (C1INH) that regulates the complement and contact system pathways by irreversibly binding target proteases (activated C1s, kallikrein, factor XIIa, factor XIa), restoring functional C1INH activity and suppressing the bradykinin-mediated vascular permeability increases that underlie HAE attacks.
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.
