对国产和进口尼莫地平注射液的稳定性作对照研究。结果表明，国产与进口注射液的尼莫地平稳定性总体上无显著性差异；然而，国产比进口注射液的尼莫地平稳定性要略差一些，这种差别体现在平均相对差值为－１．０４％；国产与进口尼莫地平注射液均显酸性，两者ｐＨ值的稳定性相差不大。
The domestic and imported nimodipine injection stability for controlled study. The results showed that there was no significant difference in the stability of nimodipine between domestic and imported injection. However, the stability of nimodipine in domestic injection was slightly worse than that of imported injection. The difference was reflected in the average relative difference of -1 .04%; Domestic and imported nimodipine injection were acidic, the stability of the pH value of the two little difference.
