We studied the effects of various infusion containers materials on the fluid volumes, different infusion fluids and fluid concentrations of nartograstim (NT), a recombinant human granulocyte colony stimulating factor, on the adsorption of NT to containers, after adding NT preparations (Neu-up^&ltss;[O!R}> for injection 100) into infusion fluids. The NT concentrations in the infusion fluids after adding NT to containers were determined by a high-performance liquid chromatographic method or bioassay. When 1000 ng of NT was added to 500 ml physiological saline in glass containers (final concentration : 200 ng/ml), the residual rates in the fluids was to 89.5% immediately after addition, and thereafter decreased 73.3% at 6 hr and 59.1% at 24 hr. Similarly, when NT was added to the same solution in polypropylene containers, the residual rates was 74.2% immediately after adding, and 37.5% at 6 hr, and 27.8% at 24 hr. The results in the ethylenvinyl acetate and polyethylene containers were also similar to those in the polypropylene containers. No influence of the volumes (100 and 250 ml) or the kinds of fluids (physiological saline, 5% glucose solution and ringer lactate solution) on the residual rates of NT in fluids was observed. As the fluid concentrations of NT were higher, the residual rates were found to be larger within the range of 100- 1200 ng/ml. These decreases in the NT concentrations in the infusion fluids could be prevented almost completely by adding commercially available total-vitamin injections containing polysorbate surfactants.
