EMERGENCE OF NATURAL SUPER-DISINTEGRNATS IN ORO-DISPERSIBLE TABLETS: AN OVERVIEW

Orally disintegrating tablets (ODTs) are an emerging trend in novel drug delivery system and have received ever-increasing demand during the last few decades. ODTs are solid unit dosage forms, which disintegrates or dissolves rapidly in the mouth without chewing and water. This type of property in dosage form can be attained by addition of different excipients, in which disintegrants are the key adjuvant. In recent years, several newer agents have been developed known as super-disintegrants. Super-disintegrants are used to improve the efficacy of solid dosage form and influence the release rate of dosage form. Diverse categories of super-disintegrants are such as synthetic, semi-synthetic, natural and co-processed blends etc. These have been employed to develop effectual ODTs and to overcome the limitations of conventional tablet dosage forms. The plant derived natural super disintegrants comply with many requirements of pharmaceutical excipients as they are non-toxic, stable, easily available, associated with less regulatory issues as compared to their synthetic counterpart and inexpensive; also these can be easily modified into more polar form. This review discuss about the development of various kind of natural super-disintegrating agents, along with their role in the tablet disintegration and as potent candidate to be used in ODTs, which are being used in the formulation to provide the safer, effective drug delivery with patient compliance
