Abstract:
OBJECTIVE:To investigate the compatibility stability of Fat-soluble vitamin (Ⅱ)/Water-soluble vitamin for in-jection with common electrolytes. METHODS:Referring to clinical common dose,Fat-soluble vitamin (Ⅱ) for injection/Wa-ter-soluble vitamin for injection collective packing [containing Fat-soluble vitamin(Ⅱ) for injection 2 ampoules and Water-soluble for injection 1 ampoule] were respectively mixed with Glucose injection,Potassium chloride injection,Concentrated sodium chlo-ride injection,Sodium bicarbonate injection,Potassium aspartate injection,Potassium aspartate and magnesium aspartate injection, Sodium glycerophosphate injection,Multi-trace elements injection (Ⅱ) to obtain mixture A-H. At room temperature (25 ℃),these mixtures were investigated in terms of appearance,pH value,osmotic pressure molar concentration and the number of insolu-ble particles at 0,1,2,3,4 h. The contents of bacterial endotoxin were tested at 0,4 h. RESULTS:Within 4 h after mixing, there was no significant change in appearance of those mixtures;pH value of mixture H changed greatly (RSD=5.13%,n=5), and that of mixture D and G increased significantly. The osmotic pressure molar concentration of those mixtures had no significantly change(RSD<2%,n=5)and lower than 600 mOsmol/kg. The bacterial endotoxin tests of those mixtures were negative. Two and four hours after mixing,the number of insoluble particles ≥10 μm in mixture B was increased significantly;2,3,4 h after mix-ing,the number of insoluble particles ≥10 μm in mixture E,F,H were increased significantly;0 ,1,2,3,4 h after mixing,the number of insoluble particles ≥10 μm in mixture G was increased significantly. There was statistical significance in the number of insoluble particle ≥10 μm in above mixtures compared to mixture A at the same time point(P<0.05),but it was in line with the standard of 2015 pharmacopeia. One,two,three and four hours after mixing,the number of insoluble particle ≥10 μm in mixture D was increased significantly,there was statistical significance compared to mixture A at the same time point(P<0.05);the num-ber of insoluble particle ≥10 μm in mixture D was beyond prescribed scope of pharmacopeia at 2,3,4 h after mixing. Within 4 h after mixing,both the number of insoluble particle ≥10 μm in mixture C and the number of insoluble particle ≥25 μm in edch mixture had no significant change,in accordance with pharmacopeia standard. CONCLUSIONS:Fat-soluble vitamin (Ⅱ)/Wa-ter-soluble vitamin for injection is not suitable for mixing with Multi-trace elements injection(Ⅱ),Sodium glycerophosphate injec-tion or Sodium bicarbonate injection due to great change of pH value and the number of insoluble particles.
