Development of novel gastroretentive drug delivery system of gliclazide: hollow beads

Aim: The current communication deals with the development of hollow floating beads of gliclazide. The primary effect of this drug is to potentiate glucose-stimulated insulin release from pancreatic islet-β-cells by induction of a decrease in potassium efflux from these cells. Because of the poor aqueous solubility, its absorption is limited. Thus, an attempt was made to improve its release profile.
