Overview on Functionality Added Co-processed Excipients for Orodispersible Tablets

Abstract

Orally disintegrating tablets are an emerging trend in novel drug delivery system and have received ever increasing demand during the last few decades. Orally disintegrating tablets ODTs are the dosage form which will disintegrate in mouth within seconds without need of water. This type of property in dosage form can be attained by addition of different varieties of excipients. But the number of fillers/binders/disintegrant which can be used for ODT formulations is limited because these bulk excipients have to fulfill special requirements, such as being soluble in water, pleasant taste, mouth feel, sweetness, and rapid dispersibility. In recent years drug formulation scientists have recognized that single component excipients do not always provide the requisite performance to allow certain active pharmaceutical ingredients to be formulated or manufactured adequately. New combinations of existing excipients are an interesting option for improving excipient functionality now a day. In excipients mannitol is used as diluents but now a day’s modified mannitol is available which give extensive flow, compression and rapid dispersibility to the tablet e.g. like Orocell, Mannogem EZ, and Pearlitol SD 200. The current review article is prepared to have a look over the recent development in excipient technology and the approaches involved in development of such excipients. It emphasizes on the different examples of functionality added materialsalso called as multifunctional co processed excipients available in market such as Ludiflash, Pharmburst, and F- MELT.
