Abstract:
Aim To evaluate the correlation between in vitro release and in vivo absorption of azithromycin cat-ionic micron niosomes (ACMNS)by Wagner-Nelson method and deconvolution method. Methods The in vitro release behavior of ACMNS was studied by dy-namic membrane dialysis. After a single dose of intra-gastric administration with ACMNS and AM in rats,the AM concentrations in plasma were determined by high performance liquid chromatography(HPLC). Wagner-Nelson and deconvolution method were used to reveal the in vitro / in vivo correlation. Results X used as cu-mulative in vitro release and Fa as the absorption per-centage,the regression equation was established:F a =3. 0524X - 5. 7709,r = 0. 8976,and X used as cumu-lative in vitro release and R as input function,the re-gression equation was established:R = 2. 3413X -58. 687,r = 0. 5217. r < r( 2,0. 05) = 0. 9500 (P <0. 05). Conclusion There is no correlation between in vitro release and in vivo absorption of ACMNS.
