Research Abstract

Novel drug carrier for ribavirin was developed for treatment of chronic hepatitis C. Polymeric nanoparticles encapsulating ribavirin were prepared fromarabinogalactan-poly(L-lysine) conjugates and poly(lactic acid). Ribavirin was specifically accumulated in the liver of mice and the amount of ribavirin was gradually decreased. Thus, it is expected that the nanoparticles are useful for treatment of chronic hepatitis C.
