Abstract
The compatibility of common additives in protein hydrolysate/dextrose solutions was studied. The additives included electrolytes (calcium gluconate, potassium phosphate and magnesium sulfate), vitamins (M.V.I., Solu B Forte, phytonadione, cyanocobalamin and folic acid), insulin and heparin sodium. Various concentrations of the admixtures were observed at intervals throughout a 24-hour period. Combinations which displayed no physical change were subjected to spectrophotometric analysis. Thin-layer chromatography was used to examine those mixtures which displayed a spectral change. The principal incompatibility problems are related to concentrations of calcium gluconate and potassium phosphate. The order of mixing affected the concentration tolerances. The vitamins, insulin, heparin and magnesium, in usual therapeutic concentrations, appeared to be compatible in the protein hydrolysate/dextrose solution.
