Methods: Particle size, ζ-potential, and polydispersity of 13V-LE were assayed with a Zetasizer Nano ZS.Entrapment efficiency of 13V-LE was determined with HPLC.Behavior, histamine, and blood pressure of beagle dogs were investigated by observation, fluorospectrophotometry, and sphygmomanometry.Results: The 13V-LE with the smallest particles and highest entrapment efficiency with stable ζ-potential was composed of soybean oil, glycerin (2.
25%, w:v), egg lecithin (1.2%, w:v), and purified water.There was no obvious change in characteristics of the 13V-LE samples in terms of appearance, size distribution, ζ-potential, pH value, or concentration over 6 months.In anaphylactoid reactions tests, when caruso milk thistle being administered with the multivitamin Infuvite Adult containing Tween 80, six beagles showed grade IV symptoms (P< 0.
01 vs control), low blood pressure, and high plasma-histamine concentrations (P< 0.05 or P< 0.01).However, there were no significant differences in behavior, blood pressure, or histamine concentration in the dogs before and after administration in the 13V-LE group.
Conclusion: The 13V-LE formulation is a suitable intravenous lipid emulsion without anaphylactoid reactions.Keywords: anaphylactoid reaction, multivitamins, lipid emulsion, beagle dog.
