Performance of Starch obtained from Dioscorea dumetorium as Disintegrant in Sodium Salicylate Tablets

Starch obtained from Dioscorea dumetorium was employed as a disintegrant in Sodium Salicylate based tablets at concentrations of 5 -15w/w. Properties of the starch evaluated include: bulk and tapped densities; water uptake by capillarity; Hausner's quotient and percent compressibility. Compound tablets were evaluated for hardness; friability; disintegration time and dissolution rate. Batches of tablets containing equivalent concentrations of AC-di-sol or maize starch were employed as standards. Results obtained indicate that Dioscorea dumetorium starch performed as much better as a disintegrant in sodium salicylate tablets as maize starch but less than Ac-di-sol
