C1 Esterase Inhibitor (Cinryze®)

NDC CODE(S)

42227-0081-XX Cinryze 500MG UNIT SOLR – (VIROPHARMA)

DESCRIPTION

C1 esterase inhibitor (C1-INH) is a normal constituent of human blood and is a serine proteinase inhibitor or serpin. C1-INH’s primary function is to regulate the activation of the complement and intrinsic coagulation pathway. It also has a role in regulation of the fibrinolytic system.

Individuals with an inherited deficiency of C1-INH suffer from sudden, recurrent edematous swellings of the subcutaneous or submucosal tissues.  This condition is known as hereditary angioedema (HAE).

Commercially, C1-INH is available in two forms, those derived from purified human plasma which has undergone multiple viral reduction steps and a recombinant analogue purified from the milk of transgenic rabbits.  Cinryze® is a human plasma-derived product formulated for prevention of angioedema attacks.
