Abstract
Objective: To study the pharmacokinetic features of microencapsulated canthaxanthin in healthy rabbit. Method: Blood samples were collected from the hind limb vein at different time point after administration of a single dose of microencapsulated canthaxanthin. Plasma canthaxanthin concentration was determined by LC-MS. The main pharmacokinetic parameters were calculated by DAS2.1 program. Result: The concentration-time data of canthaxanthin fitted to a two-compartment model. The main pharmacokinetic parameters were as follows:Tmax=300 min
Cmax=(75.761±0.739) μg · L-1
t1/2z=(527.408±208.401) min
AUC(0-t)=(23 057.221±1 582.299) μg · L-1 · min-1
Vz/F=(1 569.453±258.575) L · kg-1. Conclusion: The microencapsulated canthaxanthin is slowly absorbed
possesses large volume of distribution
and shows stable and sustained-release characteristics in body.
