Pharmaceutical preparations and medicine capable of generating and/or containing thrombin
The invention relates to a pharmaceutically active substance for producing a drug that is capable of generating thrombin or that contains thrombin and compositions comprising thereof. The pharmaceutically active substance contains (A) prothrombin (coagulation factor II) obtained from plasma or by genetic engineering, (B) coagulation factors V, VIII, IX, X obtained from plasma or by genetic engineering that at least partially may be present in their activated state, and coagulation factor XIa obtained from plasma or by genetic engineering, and (C) prion-safe, coagulation-promoting phospholipids, where the phospholipids are optionally contained in liposomes.
1. A pharmaceutical composition comprising:
(A) human prothrombin,
(B) human coagulation factors V, VIII, IX, X, which may at least partially be present in activated form, and human coagulation factor XIa, and
(C) a mixture of phospholipids where the phospholipids are selected from the group consisting of choline-phospholipids, serine-phospholipids, and ethanolamine-phospholipids, where the phospholipids are contained in liposomes,
wherein said pharmaceutical composition (i) the presence of an effective amount of calcium ion activity generates thrombin and (ii) when the product of (i) is mixed with a medicinal product containing fibrinogen, results in a mixture which coagulates within 30 to 300 seconds and is suitable for use as a tissue glue or tissue sealant.
2. A pharmaceutical composition according to claim 1 further comprising human coagulation factor VII or a mixture of human coagulation factors VII and VIIa.
3. A pharmaceutical composition according to claim 1 , further comprising human tissue factor.
4. A pharmaceutical composition according to claim 1 wherein the prothrombin and coagulation factors V, VIII, IX, X, XIa, have been rendered virally safe by a method selected from the group consisting of virus inactivation and virus partitioning.
5. A pharmaceutical composition according to claim 1 which is in deep-frozen or freeze-dried form.
6. A pharmaceutical composition according to claim 1 prepared from virus inactivated, coagulation-factor-XI- and coagulation-factor-XII-containing prothrombin complexes which are activated by kallikrein.
7. A pharmaceutical composition according to claim 1 comprising phospholipids of plant origin or plant and synthetic origin, preferably in a ratio of phosphatidylcholines to phosphatidylserines of 3:1 or of phosphatidyl-cholines to phosphatidylserines to phosphatidylethanolamines of 2:2:1.
8. A pharmaceutical composition according to claim 1 , wherein the comprised phospholipids are prepared using a phospholipid emulsion which has been subjected to ultrasonic irradiation.
9. The pharmaceutical composition according to claim 8 , where the emulsion is further subjected to sterile filtration.
