Colon targeted tablets containing prednisolone solid dispersion.

      Аннотация: From the last few decades, a great deal of research work has been devoted to the development of the site specific drug delivery system which offers several benefits over the traditional drug treatments.

Also studying the evaluation of the prepared solid dispersions and the tablets prepared ...
