Formulation and evaluation of fast dissolving tablets of granisetron hydrochloride.

ABSTRACT

Fast dissolving drug delivery systems offers a solution for those patients having difficulty in swallowing tablets/capsules etc. Granisetron hydrochloride was selected as the model drug. In the present study, an attempt had been made to prepare fast dissolving tablets of the drug using , plantago ovata mucilage and sodium starch glycolate as super disintegrants (2.5 to 10 % w/w) following by direct compression method. Formulations were evaluated for precompressional parameters such as angle of repose, carr’s compressibility index and hausner’s ratio. The tablets were evaluated for uniformity of weight, thickness, hardness, friability, drug content, wetting time, in-vitro dispersion time and in-vitro dissolution study. The prepared tablets were characterized by FTIR studies. No chemical interaction between drug and exciepients was confirmed by FTIR studies.
