Abstract

The present invention belongs to the field of medicine preparation technology, relates to medicine preparation for treating several kinds of liver and gallbladder diseases and its preparation, and is especially one kind of polyene phosphatidyl chloine infusion solution and its preparation process. The preparation process of the polyene phosphatidyl chloine infusion solution includes: adding polyene phosphatidyl chloine, co-solvent, pH regulator, antioxidant and other supplementary material into injection water; regulating pH value to 6.5-10.0; adding active carbon and filtering, adding vitamins to obtain intermediate; content meat, filtering with 0.1-0.45 micron membrane and packing. The stability test shows that the preparation process is stable and feasible; and the safety test shows that the polyene phosphatidyl chloine infusion solution has no allergic reaction, no hemolysis effect, and no irritation on blood vessel.

Description
