Abstract: The stability of dobutamine hydrochloride 4 mg/mL in 5% dextrose injection has been studied using a stability-indicating, high-performance liquid chromatography assay method. The admixture injections were stable for 30 days at 5 and 23°C. Concentrations ranged between 98.5% and 102.6% for the room-temperature samples, and 99.6% and 101.8% for the refrigerated samples, of the initial mean concentrations. The standard curves demonstrated linearity (r2>.999). Variations within and between days were less than 3%. None of the samples appeared to form a visible precipitate or changed in color or clarity and the pH of the samples remained between 3.5 and 3.7.
