    Background: Chemotherapy doses are usually prescribed on the basis of body surface area but dose banding is emerging as an efficient alternative. Dose banding presents the possibility of in-advance preparation in a Centralized Intravenous Admixture Service. Aim of the study: To evaluate the long-term stability of 5-fluorouracil at banded doses (700 mg and 800 mg) in polyolefin bags. Materials and methods: Ten polyolefin bags were prepared under aseptic conditions and stored at 23 ± 2°C for 24 days. Five of them were composed of 14 mL 5-fluorocuracil (700 g) in 100 mL 0.9% sodium chloride solution and the five other of 16 mL 5-fluorouracil (800 mg) in 100 mL 0.9% sodium chloride solution. At defined times, physical stability parameters were assessed: optical densities, pH measurements, visual and microscopical inspections. Solutions concentrations were measured using high-performance liquid chromatography coupled with a photodiode array detector. Results: No change was observed on pH and optical density measurements during the study period. Visual and microscopical inspections remained free of colour change, precipitate, microagregate or crystal. The concentrations of 5-Fluorouracil in 800 mg bags remained stable for 24 days while the concentration in 700 mg bags showed a stability of at least 17 days. Conclusion: Five-fluorouracil at banded doses of 700 and 800 mg in polyolefin bags is physicochemically stable for at least 17 days at 23 ± 2°C. These results support the possibility of in advance centralised preparation.
