Designdevelopment and characterizationof orally disintegrating tablet

The present study was an attempt to select the best possible diluent - disintegrant combination to formulate Oral disintegrating tablets of Modafinil which disintegrates in matter of seconds in the oral cavity thereby reducing the time of onset of pharmacological action.Lycoat Cross povidone and Sodium alginate were used as disintegrants. In all the formulations Magnesium stearate and talc were used as lubricant and glidant respectively.The results of the drug – excipient compatibility studies revealed that there was no chemical interaction between the pure drug and excipients.Direct compression method was employed to formulate the tablets because of its cost effectiveness and due to reduced number of manufacturing steps.The precompression parameters like bulk density tapped density Carr’s index and angle of repose were determined. All the formulations showed acceptable flow properties.
