Development and evaluation of an ideal formulation of glibenclamide by solid dispersion techniques

Boll Chim Farm. 1998 Jan;137(1):26-9.

Abstract

An attempt was taken to develop an ideal formulation of Glibenclamide. Considering the physico-chemical nature of the drug the solid dispersion system was utilised using hydrophilic and hydrophobic carriers and formulations were made by fusion as well as solvent evaporation/co-precipitation techniques. The resulting formulations were evaluated in respect of physical nature, yield, assay content and stability. The in vitro release profiles of the formulations were compared with the marketed tablet and simple physical mixtures having same composition of drug and excipients. The effects of various carriers as well as manufacturing procedures on the in vitro release rate of drug were also studied. It is observed that a suitable blend of different batches of solid dispersions containing hydrophilic and hydrophobic carriers will give an optimum formulation with quick onset and prolonged duration of action.
