Need of disintegrants and super-disintegrants in tablet formulations: a brief report
Keywords:
disintegrants, superdisintegrants, SSG, fast dissolving, orally disintegratingAbstract
The disintegrants are the agents which are added to a tablet or some capsule formulations to aid moisture penetration and dispersion of the matrix of dosage form in dissolution media. An oral solid dosage form must disperse into the primary solid particles from which it was prepared. Super-disintegrants are normally used at a low concentration, 1-10% by weight relative to total weight of dosage unit. Generally used superdisintegrants are croscarmellose sodium, crospovidone, sodium starch glycolate, etc. The selection of suitable formulation excipients and manufacturing technology is necessary for obtaining the optimized design features of orally disintegrating dosage forms.
