ABSTRACT:
Disclosed is an adhesive hemostatic agent based on non-blood constituents including DOPA, able to strongly adhere to collagen fibers. The agent includes an antifibrinolytic agent in addition to an esterified atelocollagen which is non-immunogenic and may become positively charged thereon such that the adhesive hemostatic agent has no possibility of mediating particular diseases or viral infections (HIV, HCV, HBV, CMV, etc), unlike conventional agents comprising blood constituents, and readily binds to negatively charged platelets at high adhesive strength, thus inducing quick blood coagulation. Also, provided is a method for preparing the same.
