Anatomical Therapeutic Chemical Classification System
Drotrecogin alfa is a recombinant version of the natural plasma-derived activated Protein C, from which it differs only by unique oligosaccharides in the carbohydrate portion of the molecule. Activated Protein C is a crucial coagulation regulator. Furthermore, Activated Protein C is an important modulator of the systemic response to infection and has antithrombotic and profibrinolytic properties. Drotrecogin alfa has similar properties to those of endogenous human Activated Protein C.
