Abstract:To investgate the stability of potassium sodium dehyroandroandropholide succinate for injection after it was mixed with different solvents and under different PH solutions, we dissolved the agents into different solutions,and the property,PH value,insoluble particles,related substances and contents at 0,4,8 hours after potassium sodium dehydroandroandropholide succinate for injection was mixed with 5% glucose injection,10% glucose injection,5%sodium chloride,0.9% diluted sodium chloride injection.However,unfortunately,floccus was observed when the pH value decreased to three.Therefore,the quality of the solution can be guaranteed after being stored for at least eight hours after preparation,although floccus or turbidity state is prone to occur in the solution with low ph value.
