Abstract
Alginate–chitosan nanocapsules (Alg-CS NCs) were prepared by a two-stage process. The NCs were loaded with two low molecular drugs-tegafur and Mitoxantrone Hydrochloride(DHAD). Results revealed that these two drugs exhibited different drug loading and release characteristics. The drug loading and encapsulation efficiency of tegafur (<1%) were both lower than those of DHAD with the drug loading at about 20%~60% and encapsulation efficiency over 90%. However, tegafur showed a visible burst release phenomenon and the cumulative release rate of tegafur was much higher than that of DHAD.
