VERFAHREN ZUR HERSTELLUNG EINES INTRAVENOES VER- ABREICHBAREN ANTIKOERPERHAELTIGEN IMMUNGLOBULIN- PRAEPARATES |
摘要 |
A method of preparing an intravenously administrable immune globulin preparation containing antibodies, in which human blood plasma is fractionated and an immune-globulin-containing fraction is freed from undesired protein impurities by a single or repeated precipitation with polyethylene glycol, is characterized in that the immune-globulin-containing fraction is subjected in a first purification step prior to the polyethylene glycol precipitation to a treatment with an aqueous solution of a salt of an inorganic acid, and in that at least one of the following purification steps is carried out with polyethylene glycol in the presence of a soluble carbohydrate or a non-protein-precipitating polyol, whereupon the immune globulin freed from protein impurities is precipitated from the remaining solution by water-soluble polymers and is finished in a known manner to the pharmaceutical preparation. |
