Estabilidad en suero fisiológico del busulfán intravenoso en un envase de poliolefinas

subject

description

Introduction: Although it has been used orally, the variability in its absorption and the risk of causing vomiting has lead to a push towards the intravenous use of bulsulfan. This study looks at the stability of 60 mg of busulfan, in fixed volumes of 250 mL (0.24 mg/mL) and 500 mL (0.12 mg/mL) of serum and different conservation conditions, in a new plastic pack made from polyolefin/polyamide laminates. Material and methods: High-efficiency liquid chromatography with ultraviolet detection was used to determine the concentration of busulfan derivate with sodium diethyldithiocarbamatetrihydrate. Stability was assessed for both concentrations; refrigerated and at room temperature, using the t90 of each sample. Results: The percentage of the remaining busulfan concentration at 24 h was always less than 90%. At 25 oC and 0.24 mg/mL concentration, the t90 was 8.4 h; at 4 oC and a concentration of 0.24 mg/mL it was 16.7 h; at 25 oC and a concentration of 0.12 mg/mL it was 12 h and at 4 oC and a concentration of 0.12 mg/mL it was 11.5 h. Conclusions: This study show that busulfan in a concentration of 0.24 mg/mL in serum is stable in the bags tested during a refrigerated storage period of 12 h plus two additional hours of administration of the drug.
