A pharmaceutical preparation contains protein C and a thrombolytically active substance that does not activate protein C. This preparation prevents reocclusion usually occurring in the course of thrombolysis therapy.

Pharmaceutical preparation containing protein C and a thrombolytically active substance

Pharmaceutical preparation containing protein C and a thrombolytically

The invention provides compositions having thrombolytic effects, and comprise plasmin and a plasminogen activator. Such compositions can be administered locally or systemically. The invention also provides simple and safe therapies for thrombotic states and prevention of such states.

Thrombosis agent

A thrombolytic, parenterally administrable drug containing activated protein C is provided for. The drug is free of serum amyloid P, thrombin activity, infectious agents and antibodies against protein C and activated protein C.

Parenterally administrable drug having thrombolytic activity and

A method of dissolving venous thrombi using a thrombolytic, parenterally administrable drug containing activated protein C is described. The drug can be free of serum amyloid P, thrombin activity, infectious agents and antibodies against protein C and activated protein C.

Method of dissolving venous Thrombi using drug containing activated

To produce activated protein C, protein C is treated with plasmin. Activation is effected in a quick and simple manner. Contamination of the activated protein C with thrombin is avoided.

Method of preparing activated protein C

There is disclosed a pharmaceutical preparation based on Lys-plasminogen and available in the lyophilized form. This preparation contains a serine-protease inhibitor and optionally an inhibitor co-factor, preferably in an amount of 0.5 to 30 nmol per mg Lys-plasminogen. This preparation is free of side-effects and may be used for the treatment and prophylaxis of plasminogen deficiency syndromes and thromboses as well as for the production of thromboresistant artificial organs.

Pharmaceutical preparation based on Lys-plasminogen

There is disclosed a method of inactivating reproducible filterable pathogens in blood plasma products by applying elevated temperatures. The blood plasma products are heat treated in a solid state in a closed inactivation container in the presence of specific amounts of water and organic compounds, provided that the water substantially remains physically bound to the blood plasma products, while the organic compound is present in a gaseous form in the atmosphere. The water content of the blood plasma products is 0.08 to 0.40. The concentration of the organic compounds in the gaseous phase is 0.01 to 10 g per liter of container volume.

Method of inactivating reproducible filterable pathogens in blood plasma

There is described a method of inactivating reproducible pathogens in preparations containing plasmatic enzymes and proenzymes, activated or non-activated coagulation factors, such as Factors II, V, VII, VIII, IX, X, XIII, 'FEIBA', prothrombin complex preparations, plasmatic inhibitors, immunoglobulins or other blood products, such as fibronectin and fibrinogen. In order to break and overcome the protective effect of proteins on pathogens by simultaneously preserving the biological activity and the molecular integrity of the proteins, the preparation is adjusted to a salt concentration of more than 0.5 molar by the addition of ammonium sulfate and is thermally treated, whereupon the ammonium sulfate is removed from the preparation.

Method of inactivating reproducible pathogens

A method of inactivating viruses in blood products is described, wherein the blood products are heat-treated in a humid or in a solid state in the presence of inorganic or organic hydroxyl group-containing compounds having an H.sup.+ -dissociation constant of &lt;10.sup.-11 in a concentration of more than 0.05 (5% by weight) and less than 0.70 (70% by weight). The hydroxyl group-containing compounds may be water, methanol, ethanol or mannitol. The temperature may amount up to 121.degree. C., the heat treatment may last from 1 s to 100 h. The inactivation method may be applied for producing blood products selected from enzymes, proenzymes including coagulation factors, enzyme inhibitors, immunoglobulins, albumin, plasminogen, fibrinogen, fibronectin or plasma, the inactivation destroying any reproducible filterable pathogens that might be present.

Method of inactivating reproducible filterable pathogens in blood

There is disclosed a method for the production of therapeutically administrable plasma derivatives filled in final containers, which are free of prekallikrein activator, hypotensively active constituents and other undesired pharmacologically active substances, of plasma or plasma crude fractions by stepwise enrichment of the plasma proteins, sterile filtration and optionally virus inactivation. In order to make available such plasma fractions that do not develop pharmacologically negative side effects when applied and are producible with an improved activity and yield, C.sub.1 -esterase inhibitor is added during the production process of the plasma derivative, yet prior to its filling into final containers.

Method for the production of therapeutically administrable plasma

In a method of producing a blood-coagulation-promoting preparation based on human proteins and having a content of coagulation factors II, VII, IX and X and factor-VIII-inhibitor-bypassing-activity (FEIBA), human plasma is treated with sulphated high-polymer carbohydrates and/or with basic ion exchangers, the protein mixture with generated FEIB-activity is adsorbed on the ion exchanger, and the preparation is gained by elution and concentration.
