Embodiment Construction

[0014] In the embodiment, the injection is prepared in 10000ml, and the subpackage adopts 250ml glass bottles. Sterilization is performed by autoclaving at 105°C for 40 minutes. After adding the pH regulator, use 0.1M sodium hydroxide solution or hydrochloric acid to adjust the pH to 5.5-6.5 (if the pH is qualified, it is not necessary to add more).

[0015] Described injection adopts following method to prepare

[0016] 1) Take 70% to 75% of the prescribed amount of water for injection, heat it to 45-50°C under nitrogen protection, add lysine acetate, arginine, and histidine and stir until completely dissolved, add the prescribed amount of lactic acid or For other pH regulators, use hydrochloric acid to adjust the pH value to 5.0~5.5, and then add tryptophan, cysteine ​​hydrochloride, leucine, isoleucine, valine, methionine, threonine, alanine Amino acid, proline, serine, glycine, phenylalanine, and sodium metabisulfite are fully stirred to dissolve completely, and water fo...
