ABSTRACT
Objective:
To investigate the compatibility stability of cinepazide maleate injection and dopamine hydrochloride injection and explore the basis for the combined application of cinnamazide maleate injection and dopamine hydrochloride injection.Methods:
A method for determining cinnamazide maleate injection and dopamine hydrochloride injection was established using an ultraviolet-visible spectrophotometer and verified from March 1, 2021 to May 20, 2021. The color and pH value of the solution prepared using the two drugs were determined within 5 hours at room temperature. The content change of the prepared solution was determined using an ultraviolet-visible spectrophotometer.Results:
The linear range of the mass concentration of cinnamazide maleate was 4.03 - 32.24 mg/L and the linear range of dopamine hydrochloride was 20 -120 mg/L. At 25 ℃, the color of the prepared solution did not change within 5 hours and the pH value was in the range of 4.43 ± 0.06, indicating that the pH of the prepared solution did not change markedly. The concentrations of cinnamazide maleate and dopamine hydrochloride were (98.23 ± 1.09)% and (99.96 ± 0.41)% respectively, indicating good stability.Conclusion:
The prepared solution using cinepazide maleate injection and dopamine hydrochloride injection can be used within 5 hours at 25 ℃.
