In the present work, taste masked resinates of levofloxacin using Tulsion-335, an acidic cation ion exchange resins were used to develop its oral suspension formulations. The drug resin complexes were prepared by batch process by taking drug to resin ratios of 1:1, 1:2, 1:3 and 1:4. The techniques of differential scanning calorimetry (DSC), X-ray diffraction (XRD) and Fourier transform infrared...
