Formulation and Characterization of Taste Masked Mouth Dissolving Tablets of Tramadol HCl Using Different Approaches

Abstract

To overcome difficulty in swallowing tablets or capsules, scientists have considerably dedicated their effort to develop novel drug delivery systems which enhance safety and efficacy of drug molecule and to achieve healthier patient compliance. One such approach is mouth dissolving tablets (MDT). The purpose of this research was to mask the intensely unpleasant taste of tramadol HCl by inclusion complexation, complexing with resin and solid dispersion to formulate mouth dissolving tablets of the taste-masked drug. Tablets were formulated by wet granulation method using excipients. All formulations were evaluated for dispersion time, wetting time, % friability, content uniformity and in-vitro dissolution rate. Formulations with Kyron T314 showed the least disintegration time and wetting time. In-vitro drug release study of taste masked tablet showed complete drug release within 15 minutes and successful masking of taste and rapid disintegration of the formulated tablets in the oral cavity.
