| Abstract: | ??OBJECTIVE To prepare capsaicin-solid lipid nanoparticles (CAP-SLNs) and study their physical and chemical properties. Then, the CAP-SLNs were modified with chitosan (CTS) and the pharmacokinetics across colon of rats was studied in vivo. METHODS CAP-SLNs were prepared by emulsion-solvent evaporation method. The mean size, encapsulation efficiency and drug loading of the nanoparticles were investigated. RESULTS The average diameter of CAP-SLNs was (118.89??25.0) nm, the encapsulation efficiency was (38.56??2.6)%, and the drug-loading was (6.17??0.21)%. After colon-specific delivery in rats, the AUC0-360 min(243.63??61.46) mg??min??L-1 and ??max(1.23??0.18) mg??L-1 of CTS-CAP-SLNs were 1.81-fold and 1.95-fold higher than CAP. CONCLUSION It is simple and feasible to prepare CAP-SLNs by emulsion-solvent evaporation method. The pharmacokinetic parameters in rats are improved remarkably compared with CAP. |
