Abstract

Abstract A pharmaceutical composition suitable for the treatment and prophylaxis of hemophilia A or B, which comprises coagulation factor VIII or IX and a protease inhibitor (particularly aprotinin) which are incorporated in liposomes and optionally lyophilized and/or encapsulated in intestine capsules. The composition can give high absorption of the required coagulation factor from intestinal tract without being decomposed in gastrointestinal tract even by administration in oral route.
