Abstract: The present invention relates to a powder type hemostatic composition and method for preparing the same, and more specifically, to powder aggregate having porosity obtained by combining powder of biocompatible hemostatic material with a binder and a method for preparing the same, and a powder type hemostatic composition which comprises the powder aggregate and shows improved hemostatic performance as compared with simple powder hemostatic agents, and can be used to a large surface area for hemostasis, or to narrow, thin or other sites to which approach for hemostasis is difficult.

Abstract: Disclosed is a formulation for coating a medical device which comprises an anti-scarring agent and a biocompatible polymer for regulating the release of the anti-scarring agent, wherein the mass ratio of the biocompatible polymer to the anti-scaring agent is from 100:15 to 100:0 in which 0 is not included. The present formulation can be advantageously used for coating medical devices for a sustained release of the agents from the device, thus effectively minimizing or preventing the formation of scar tissues resulted from the use of implantable and non-implantable medical devices.
