Mouth disintegrating tablets of taste-masked Ondansetron HCl

Ondansetron HCl is used in the management of nausea and vomiting induced by cytotoxic chemotherapy and radiotherapy and is bitter drug. The purpose of research work was focused on taste masking of the Ondansetron HCl and further development of the drug in mouth disintegrating tablets. Ion exchange resins, Indion 204 and Indion 234 were used with a view to mask the taste of the drug. Tablet formulations were prepared using wet granulation and direct compression techniques. All formulations were subjected to post compression parameters like uniformity of thickness, hardness, friability test, weight variation and drug content uniformity, all these parameters were within pharmacopocial limits. Formulations FW 6 and FD 2 showed 102.34 +/- 1.34 and 101.94 +/- 1.54 % of drug release after 15 min, respectively. Volunteer did not feel bitter taste with these formulations (FW 6 and FD 2). These selected formulations were subjected for stability studies and were found to be stable for 3 month at 45 5 degrees C/75 +/- 5 % RH with insignificant changes in all post compression parameters.
