Abstract
Gellan gum (GG) is a bacterial exopolysaccharide obtained commercially from Sphingomonas paucimobilis. Two chemical forms of GG exist, i.e. native/acylated and deacylated. Ionotropic/ionic gelation is a promising tool in the development of biocompatible novel drug delivery systems. GG is a naturally occurring polysaccharide that bears the potential to encapsulate a large number of micro- and macro-therapeutic molecules via different carrier systems such as microspheres, hydrogels, beads and microparticles. By the achievements of polymer chemistry, development of intelligent and the strategic encapsulation techniques helps the natural polysaccharide to use in numerous drug delivery. The usage of expensive and toxic organic solvents in the microencapsulation process has been significantly minimized by the progress of ionotropic gelation method. Ionically gelled GG delivers great prospects for designing new drug delivery systems, thus encompassing the frontier of future pharmaceutical development.
