Abstract:
Objective To explore the pharmacokinetic properties of curcumin nano emulsion and its pharmacodynamic effects on hyperlipidemia in rats. Methods The method for determination of curcumin was established by HPLC-MS. The pharmacokinetics characteristics of curcumin nano emulsion oral administration system were investigated. SD rats were used as model animals to establish hyperlipidemia animal models, and the pharmacodynamic effects of curcumin nano emulsion on hyperlipidemia induced by high fat diet was preliminarily investigated. Results The results of pharmacokinetic studies in vivo showed that the relative bioavailability of curcumin nano emulsion was 313.47% with bulk drug group as the reference preparation. The relative bioavailability of curcumin nano emulsion was 279.52 % with tablets as reference preparation. Cmax of curcumin nano emulsion group was 201.48 % of that of bulk drug group and 193.02 % of that of tablet group, and had higher MRT value (183.52 % of that of bulk drug group and 154.21 % of that of tablet group) than bulk drug group and tablet group. Pharmacodynamics research results showed that curcumin nano emulsion oral administration system could significantly reduce the levels of triglyceride and LDL-c in serum of model rats, and relieve liver lipid deposition and liver injury caused by high-fat diet in model animals. Conclusion The oral administration system of curcumin nano emulsion could effectively improve the bioavailability of curcumin, which has a good hypolipidemic effect. It also could control the weight gain of hyperlipidemia rats and improve the changes of liver coefficient caused by lipid metabolism disorder.
