As day’s passes, demand for the faster disintegrating formulation is increased. So, the pharmacist needs to formulate disintegrants i.e. super disintegrants which are effective at low concentration and have greater disintegrating efficiency, and they are more effective intragranular.This review describes the various advantages, excipients used,super-disintegrate employed,drugs eligible for FDTs, different techniques used for preparing FDT, various patented technologies, evaluation parameters.
