Gelled Microparticles/Beads of Sterculia Gum and Tamarind Gum for Sustained Drug Release

Abstract

In recent years, a variety of biocompatible natural polysaccharides are extensively investigated as pharmaceutical excipients in designing various pharmaceutical formulations. Among these, sterculia gum and tamarind gum have emerged as two popular biopolymer candidates, which have found their applications in designing of various sustained drug releasing dosage forms. Presently, both sterculia gum and tamarind gum have been employed to design oral multiple unit sustained release systems such as microparticles, beads. The present chapter deals with a helpful and comprehensive discussion on already reported different microparticles/beads made of sterculia gum and tamarind gum, which have shown a promise in sustained drug releasing capacity over a longer period after oral administration. This chapter will be helpful in applying appropriate strategies or achieving desired controlled sustained drug release profiles from microparticles/beads made of sterculia gum and tamarind gum.
