Abstract

Recently, various natural polysaccharides have been widely used in the development of pharmaceutical drug delivery systems. These are being exploited as binders, granulating agents, gelling agents, mucoadhesive agents, matrix formers, release retardants, etc., in various drug delivery dosage forms. Among different plant polysaccharides, it has been reported that tamarind gum (TG) extracted from tamarind seed kernel could be a promising drug delivery excipient in the development of various dosage forms like suspensions, emulsions, tablets, beads, spheroids, microparticles, nanoparticles, ophthalmic preparations, buccal patches, colon-targeted drug delivery, etc. The present chapter includes a comprehensive and useful discussion of TG in drug delivery systems. In addition, this chapter also briefly discusses source, isolation, chemical composition, and properties of TG.
