Objective: To study the prescription technology and relevant contents of quality standards of aerogenic agent for double contrast radiography, and determinereasonable method and limit requirements according to the clinical requirements and the determination results of the samples, so as to provide scientific basis for the quality control of aerogenic agent for double contrast radiography. Methods: Sodium bicarbonate, citric acid and sodium salt were identified by the chemical reaction. The gas production was measured by carbon dioxide gas generator. The method and limit requirements of the time and volume of gas production were determined, according to the clinical needs, combined with the sample measurement results. The reasonable determination method and limit requirements of loss on drying was compared and determined. The microbial limit determination method was determined, and the limits of dispersion, particle size and weight variation were determined. HPLC method was used for the determination of citric acid. The chromatographic column was Phenomenex-C18 column (250 mm×4.6 mm, 5 μm). The mobile phase was methanol-0.2% phosphoric acid (5∶95), the flow rate was 0.8 mL·min-1, the detection wavelength was 215 nm, the column temperature was 25 ℃, and the injection volume was 10 μL. Results: The identification reactions were specific and negative without interference. The volume of gas production should not be less than 360 mL, and the gas production time should be within 2 min. The weight loss of drying was determined by vacuum drying method at room temperature, and the limit requirement was no more than 0.2%. The method for microbial limit test was determined and the methodological validation was completed. The test methods for dispersion, particle size and weight variation were consistent with that in Chinese Pharmacopoeia. The linear range of citric acid was 1.625 8-3.793 6 mg·mL-1 (r=0.999 9). The limit of quantification for citric acid was 10.84 μg·mL-1. The RSDs of precision and repeatability tests were less than 1.5% (n=9). The average recovery of citric acid was 100.2% with the RSD of 1.8% (n=9). The determination results of citric acid in 3 batches of samples were 42.7%, 42.8% and 41.5% respectively. Conclusion: The items of the drug quality standard established in this study are comprehensive, the methods are feasible and the limits are reasonable, and it can be used for the quality control of aerogenic agent for double contrast radiography.
