Goal: The preparation injection with spurts the past Luo river Wei freezing and drying medicine in powder form for injections medicinal preparation and establishes its quality control method. Method: Inspects the pH value to spurt the past Luo river Wei solubility the influence, the excipient to the product formation outward appearance influence, the screening technological conditions, obtains the best prescription and the preparation craft, and to the prescription which and the preparation craft screens carries on the confirmation, confirms its feasibility. Then determines its content by the ultraviolet spectrophotometric method, and take the content, the related material inspects its quality as the major targets or quotas. Finally: The definite solution pH value in 11.3~11.5, spurts the past Luo river Wei density in 10.0μg~50.0μg/ml the scope, the density and the absorbancy assume the good linear relationship, in the content determination the average returns-ratio are 99.34% (RSD=0.31%). The injection with spurts the past Luo river Wei's each examination target even sign to achieve the quality specification the request. Conclusion: The prescription is reasonable, the preparation craft is feasible, the product quality is controllable.
