This work presents results of the preparation and characterization of nanoparticles for entrapping cytarabine, a chemotherapeutic agent. The particle size analysis indicated a uniform particle size. The study of the release of drug from nanoparticles exhibited a prolonged release profile as studied over a period of 16 hours. The drug release was constant from the 10th to the 16th hours, which showed that the formulation was successful for longterm treatment. The drug entrapment efficiency of the nanoparticles having the same ratio of polymer and drug was about 90.2%. The physical stability of the nanoparticles was good as studied over a period of 4 weeks. These results are promising for producing nanoparticles by entrapping cytarabine, which can be useful for cancer therapy.
