Terbutaline sulfate, developed by astrazen and marketed in sweden in 1981, is a β 2 adrenoreceptor agonist that, by selectively exciting the β 2 receptor to dilate the bronchi, increases mucociliary clearance due to decreased obstructive pulmonary disease, thereby accelerating mucus secretion clearance. Has effects of relieving asthma, eliminating phlegm, and dilating bronchus. The traditional Chinese medicine composition is mainly used for relieving bronchospasm combined with bronchial asthma, chronic bronchitis, emphysema and other lung diseases in clinic.

Sample detection:
the stability of the liquid medicine in a short time is examined after the liquid medicine is left for 72 hours before filling in example 1, example 2, example 3, comparative example 1 and comparative example 2, and the items including properties and impurities are examined. The results are detailed in table 1.
The sample in example 3 is placed under the accelerated condition for 6 months, the stability is inspected, and the inspection items comprise characters, pH, content and impurities. The results are detailed in table 2.
The detection method comprises the following steps:
the characteristics are as follows: visually, the solution should be colorless and transparent.
The pH value should be 3.0-4.5 (the general rule of the four kingdoms of the China pharmacopoeia 2020 edition 0631).
Terbutaline sulfate content: the chromatographic conditions are the same as impurities. 90.0 to 110.0 percent of terbutaline sulfate.
The impurity detection method comprises the following steps:
using a C18 column, taking 4.23g of sodium hexanesulfonate, adding 750mL of 0.05mol/L ammonium formate solution and 250mL of methanol, and uniformly mixing to obtain a mobile phase; the detection wavelength is 276 nm; and taking a sample for detection.
Limitation: the impurity B and the impurity C are not more than 0.2 percent, other single impurities are not more than 0.2 percent, and the total amount of the impurities is not more than 1.0 percent.

Remarking: the unknown impurity content is neglected below 0.05%.
TABLE 2 accelerated 6 month stability
Remarking: the unknown impurity content is neglected below 0.05%.
As can be seen from the stability review data of the examples and comparative examples 72h of Table 1: the samples of examples 1, 2 and 3 were left for 72 hours, and almost no impurities were detected, while the comparative example was left for 72 hours, and the impurities reached 0.19%, which was close to the maximum limit of impurities, during which time the data was out of limit. The main difference between the examples and the comparative examples is the passivation process, such as: the difference between examples 1 and 2 in comparison with comparative example 1 is that examples 1 and 2 have one more passivation step before liquid preparation than comparative example 1; for another example: example 3 and comparative example 2 both used a pre-dispense rinse, and the same dispense, filter, and fill, with the only difference being that example 3 has one more passivation step. Therefore, the process treatment method for improving the stability of the terbutaline sulfate atomized liquid can reduce the impurity content from 0.19% or even higher to 0%, effectively control the impurities of the terbutaline sulfate in the production process, and ensure the stability of the product in the production process.
As can be seen from the data of the example shown in the table 2, the sample is placed for 6 months under the accelerated condition, and the properties, pH, content and impurities of the sample are basically not changed. Therefore, the process treatment method for improving the stability of the terbutaline sulfate atomized liquid can ensure the stability of the product for a long time.
