Abstract

The purpose of this research was to mask the intensely bitter taste of Chloroquine phosphate using ion exchange resin and to formulate oral suspension of the taste masked drug. Batch method was used for formation of drug resin complex. Various ion exchange resins such as Doshion P 544 S and Kyron T- 114 were tried to obtained taste masked drug resin complex (DRC). Optimization of drug loading was carried out. With Doshion P 544 S, the drug-resin proportion of 1:4 achieved equilibrium in 5 hours. 96% w/w of drug loading was possible by this method. Complex formation was confirmed by DSC and IR studies. Oral taste masked suspension was prepared using xanthum gum at various concentrations 0.1%, 0.2% and 0.4% respectively. CPR 1 and CPR 2 batches showed satisfactory assay result that is it fulfills the official requirements. But physical properties of suspension were not satisfactory. CPR 1 was not easily redispersible and with CPR 2 caking was observed with sedimentation volume of 0.4, hence these batches were rejected. CPR 3 was found to be optimized batch as it showed complied assay results were found to be easily redispersible even after 7 days with no cake formation and sedimentation volume of 0.98. and was evaluated for various parameters such as Colour, pH, Viscosity etc. Thus, successful taste masking and formulation of suspension with taste masked drug especially for pediatric, geriatric, and non cooperative patients.
