The following are claimed: (1) a pharmaceutical composition for treating blood clotting disorders, containing ≥ 2 clotting factors that are components of a pro-thrombinase or pro-pro-thrombinase and are free of phospholipids; (2) a composition containing purified prothrombin as the sole active ingredient; (3) a composition for treating clotting disorders, containing biologically active purified prothrombin; (4) a complex consisting of prothrombin, factor Xa and optionally factor V or Va; (5) a complex consisting of prothrombin and factor V or Va; (6) a complex consisting of factor X and factor V or Va; (7) a preparation containing the complex of (4), (5) or (6) and calcium ions; (8) a process for preparing a purified pharmaceutical prothrombin composition, comprising subjecting a prothrombin complex concentrate to chromatographic purification and converting the fraction containing prothrombin into a pharmaceutical preparation; (9) a prothrombin composition obtainable by the process of (8) which is free of thromboembolic side effects at a dose of ≥ 150 U prothrombin/kg, as expressed by a score of ≤ 3 in the Wessler thrombosis model, and which in freeze-dried form can be reconstituted to a clear solution with an activity of ≥ 10 U prothrombin/ml in a dissolution time of ≤ 1 minute, and (10) use of purified pro-thrombinase factors to produce a pharmaceutical preparation for establishing supra-normal prothrombin concentrations in the blood of a patient. |
