Results of an in vitro study on the release of gentamicin
sulphate niosomal vesicles prepared using Tween 60, Tween 80
or Brij 35 are shown in Figs. 3, 4 and 5, respectively. The
percentage of drug released after 8 h (Q8h) from the prepared
niosomal vesicles are shown in Table II. Niosomal formulations
showed slower release rate than gentamicin solution. Significant
changes in release were observed upon changing the type
of surfactant used in the bilayer of gentamicin niosomes.
