Stability of fluorouracil in plastic containers used for continuous infusion at home.
The stability of fluorouracil when prepared and stored in plastic containers used for continuous infusion in home therapy was studied. Fluorouracil was diluted with 5% dextrose injection. Samples were stored for 16 weeks at 5 degrees C and room temperature in polyvinyl chloride drug reservoirs and at 5 degrees C in elastomeric balloons used in a disposable drug pump. Periodically, samples were tested by a stability-indicating high-performance liquid chromatography (HPLC) assay. At 5 degrees C, there was no significant degradation. At room temperature, there was a progressive increase in fluorouracil concentration, presumably because of evaporation of water. A 10% change in the fluorouracil concentration over 55 days was predicted. Fluorouracil is stable in 5% dextrose injection for at least 16 weeks when stored at 5 degrees C in the two types of containers studied.
