Factor VIII Inhibitor Bypassing Activity (Feiba) 50 U/ml is available in three different presentations: The presentation 500 U Factor VIII Inhibitor Bypassing Activity (Feiba) contains 500 U factor VIII inhibitor bypassing activity in 200-600 mg human plasma protein, The presentation 1000 U Factor VIII Inhibitor Bypassing Activity (Feiba) contains 1000 U factor VIII inhibitor bypassing activity in 400-1,200 mg human plasma protein, The presentation 2500 U Factor VIII Inhibitor Bypassing Activity (Feiba) contains 2500 U factor VIII inhibitor bypassing activity in 1,000-3,000 mg human plasma protein.
Factor VIII Inhibitor Bypassing Activity (Feiba) also contains the factors II, IX and X, mainly in non-activated form, as well as activated factor VII. Factor VIII coagulation antigen (F VIII C:Ag) is present at a concentration of up to 0.1 U./1 U. Factor VIII Inhibitor Bypassing Activity (Feiba). The factors of the kallikrein-kinin system are present in trace amounts only, if at all.
