Formulation and evaluation of immediate release tablet of risperidone

The main objective of the present investigation was to formulate Risperidone immediate release tablet. Risperidone, an antipsychotic drug mainly act as a D2 and 5HT2A receptor antagonist. Superdisintegrants agents like kollidon and citric acid were used and compressed into tablet by direct compression method. Risperidone is mainly used to treat schizophrenia bipolar disorder. The six formulations having different concentration of superdisintegrants were prepared and formulation blend was examined for angle of repose, bulk density tapped density and compressibility. The tablet were evaluated for various parameters like hardness, thickness, friability, weight variation, disintegration time and invitro dissolution time, all the parameter were found within limits.
