Cyclodextrin polymer, a new tablet disintegrating agent.
Cyclodextrin (CD) polymer, a type of crosslinked cyclodextrin, has been evaluated as a new tablet disintegrating agent in comparison with four common disintegrants (crosslinked polyvinylpyrrolidone, crosslinked carboxymethyl cellulose, formaldehyde casein and corn starch). Physical properties of the disintegrants have been studied. Tablets made by direct compression using microcrystalline cellulose as binder, magnesium stearate as lubricant and talc as antiadherent have been compared. The parameters evaluated were disintegration time, hardness and friability. CD polymer performs well as a tablet disintegrating agent with results paralleling those of crosslinked carboxymethyl cellulose (Ac-Di-Sol) and superior to the other three.
