  • Title: [Preparation of acyclovir-polybutylcyanoacrylate-nanoparticles by emulsion polymerization method].
    Author: Zhang Z, Tian H, He Q.
    Journal: Hua Xi Yi Ke Da Xue Xue Bao; 1998 Sep; 29(3):329-33. PubMed ID: 10684106.
    Abstract:
    The aim of this study was to optimize the conditions and technology of preparing acyclovir-polybutylcyanoacrylate-nanoparticles (ACV-PBCA-NP) which has the diameter of about 100 nm and the shape of a sphere. The influential factors on sphericization were observed by single factor optimization. The preparation conditions and technology were optimized by the even design method. The contents of acyclovirin in acyclovir polybutyloganoacrylate nanoparticles were determined by HPLC. The optimum conditions and technology of preparing acyclovir polybutylcyanoacrylate nanoparticles were decided and put into use. The average diameter of the ACV-PBCA-NP thus prepared was 108.5 +/- 94.8 (n = 588). Its embedding ratio was 71.8%, and drug loading was 18.5%. The results suggest that the conditions and technology of preparing ACV-PBCA-NP presented in this paper are stable and practical.
