    disintegration in the oral cavity without water. To achieve this goal, mannitol used as diluent and sodium saccharin as sweetening agent for the formulation of tablets. Attempts were made to enhance dissolution rate along with faster disintegration using superdisintegrants like Ac-Di-Sol,4 Sodium starch glycolate (SSG)5 and Kollidon CL6 in the The disintegration time for mouth dissolving tablets needs to be modified, as disintegration is required without water; thus the test should mimic disintegration in salivary content. For this purpose, a Petri dish (10 cm diameter) was filled with 9 ml of phosphate buffer solution, pH 6.8 (which correlated pH of saliva). The tablet was

    An Overview of Disintegrants | LFA Tablet Presses

    The disintegration time of water-soluble tablets remains almost the same with or without the introduction of nonionic surfactants; however when surfactants are added the rate of water penetration generally increases especially for granules that are made with slightly soluble materials. 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
