Abstract

The invention provides a preparation process of high-concentration compound amino acid injection. The preparation process of the high-concentration compound amino acid injection is characterized by comprising the following steps of (1) pretreatment by preparation tanks and pipelines; (2) injection preparation process; (3) filling; (4) sterilization; and (5) packaging. The injection preparation process comprises the following steps of grouping and charging according to different amino acid solubilities and solubility characteristics, and dissolving in batches at the water temperature of 70 DEG C according to the difficulty level; closing the preparation tanks after complete dissolution, extracting air in a thick mixing tank and a thin mixing tank respectively until the pressures in the tanks are negative pressures, and introducing high-purity nitrogen into the tanks until the pressures are positive pressures; meanwhile flushing activated carbon in a titanium bar back into the thick mixing tank by water for injection; and then removing carbon for a medicine liquid in the thick mixing tank by the titanium bar, transferring the medicine liquid to the thin mixing tank, and making up to volume by the rest water for injection with prescribed dose to full quantity after the transferring is completed. The problems that the high-concentration compound amino acid injection is yellow in color, the content of tryptophan and the like is lowered excessively, and the amino acid injection is unstable in quality during a storage period are solved.

Description

technical field [0001] The invention belongs to the technical field of pharmaceutical products, and mainly relates to a preparation method of 15% compound amino acid injection (17AA), specifically a preparation process of high-concentration compound amino acid injection.
