Problems solved by technology

According to the existing Pharmacopoeia records, the production process from protein stock solution to finished product has not been made public. In practice, the specific processes adopted by various manufacturers are quite different. It is difficult to control the quality of the finished product, which is likely to cause pollution of the product itself and directly affect its safety. sex

Embodiment 1

[0024] A production process of human immunoglobulin for intravenous injection according to the present invention, as shown in Figure 1, includes collecting healthy human plasma as a raw material according to the requirements of Pharmacopoeia, adopting low-temperature ethanol protein separation method to prepare human immunoglobulin stock solution, and pressing the finished product Specification preparation, verification, the production process from protein stock solution to finished products with protein concentration of 5% and 10% includes the following steps:

[0025] A) Concentrate the protein stock solution by ultrafiltration to a concentration of 5.5%±0.5%, add maltose to a content of 10%±1%, and adjust the pH value of the protein solution to 3.8-4.4 with 1M / L HCl;

[0026] B) Filter the protein solution through a 0.2 μm sterile filter element, and put it into a sealed serum bottle;

[0027] C) placed in a low pH incubation room, and incubated at a low pH of 24°C ± 1°C fo...

Abstract

The present invention relates to production process of human immune globulin for intravenous injection with raw protein liquor. The raw protein liquor is first diluted and added with certain amount of maltose as the stabilizer, and then virus deactivated and eliminated to obtain two types of human immune globulin product for intravenous injection in the human immune globulin concentration of 5 % and 10 % separately. The production process has easy operation and saving in maltose, and the products has high safety.

Description

technical field [0001] The invention relates to the production process of human immunoglobulin for intravenous injection, especially the production process from protein stock solution to finished product. Background technique [0002] Human immunoglobulin for intravenous injection (referred to as "human immunoglobulin for intravenous injection") is isolated and purified from healthy human plasma by low-temperature ethanol protein separation method or other approved separation methods to remove anti-complement activity and undergo virus inactivation treatment, produced biological products. The manufacture and verification of this product are recorded in the 2005 edition of the Chinese Pharmacopoeia. According to the existing Pharmacopoeia records, the production process from protein stock solution to finished product has not been made public. In practice, the specific processes adopted by various manufacturers are quite different. It is difficult to control the quality of th...
