Pharmacokinetics of curcumin solid dispersion in mice

Aim To study the pharmacokinetics of curcumin-pvp solid dispersion ig administration in mice in comparison with the free curcumin suspension.Methods Drugs were administered at a dose of 300 mg·kg-1 via ig.The plasma concentration of curcumin was determined by HPLC,the pharmacokinetics were calculated by DAS ver1.0 program.Results The curcumin pharmacokinetics conforms to a two-compartment open model after a single ig dose of curcumin solid dispersion in mice.The parameters were as follows:T12α and T12β were 16.4 and 266.1 min,respectively.AUC was 89.6 mg·L-1·min-1,Vd was 763.9 L,V1 was 51.0 L,and CL was 1.99 L·min-1.The absorption rate of curcumin solid dispersion was 6.75 times as much as curcumin suspension.Conclusion The curcumin solid dispersion improves the absorption of curcumin in vivo in mice evidently.
