1％盐酸丁卡因水溶液化学稳定性考察

Study on the chemical stability of 1% tetracaine hydrochloride solution

本文分别用经典恒温法和初均速法对１％盐酸丁卡因溶液进行了稳定性实验，两种方法的实验结果相符；室温（２５℃）下的贮存期分别为１．６４年和１．６９年。通过实验证明，与经典恒温法比较，初均速法工作量小，省时，且数据处理较简单，是一种简便易行的方法。

The stability test for 1%tetracaine hydrochloride solution was studied using classical constant-temperature and initial aver-age rate method respectively. The shelflife at room temperature was 1.64 and 1.69 year respectively. Experiments proved thatthe inital average rate method can be used because it is time saving and simple in data processing in contrast to the classical con-stant-temperature method.
