雷尼替丁注射液通过输液给药应用于胃、十二指肠溃疡及炎症所致的急性上消化道出血、十二指肠炎及糜烂等疾病。现特别观察雷尼替丁在输液中的稳定性。将雷尼替丁配制成适当浓度的水溶液，用UV-754分光光度计在200～400nm波长处扫描，制备标准曲线，两个吸收峰的最大吸收峰为228 Ranitidine injection by infusion applied to the stomach, duodenal ulcer and inflammation caused by acute upper gastrointestinal bleeding, duodenal inflammation and erosion and other diseases. In particular, ranitidine in infusion stability. The ranitidine formulated into the appropriate concentration of aqueous solution, with a UV-754 spectrophotometer at 200 ~ 400nm wavelength scanning to prepare a standard curve, the maximum absorption peak of two absorption peaks 228
