DEVELOPMENT AND EVALUATION OF DROTOVERINE TASTE MASKED TABLETS WITH IMPROVED DISSOLUTION EFFICIENCY USING SOLID DISPERSION TECHNIQUE
Journal Title: Indian Journal of Research in Pharmacy and Biotechnology - Year 2013, Vol 1, Issue 3
Abstract
The purpose of this research is to mask the bitter taste of the drug, Drotoverine using solid dispersion technique. The taste-masked drug is formulated in to a conventional tablet by direct compression method for ease of administration. Taste masking was done by solid dispersion using polymer such as urea and mannitol by melting/fusion method Fourier transform infrared spectroscopy (FTIR) and scanning electron microscopy (SEM) were performed to identify the physicochemical interaction between drug and carrier, hence its effect on dissolution. Conventional taste masked tablets were evaluated for weight variation, disintegration time, hardness and friability. In vitro drug release studies were performed for conventional tablets of drotoverine. Bitterness score was evaluated on volunteers. FTIR spectroscopy and SEM showed no interaction between drug and carriers. Conventional tablets prepared using solid dispersion, showed faster disintegration and complete bitter taste masking of drotoverine. In addition the prepared tablets exhibited better dissolution profile. Taste evaluation of taste masked tablets in human volunteers rated tasteless with a score of 0. Thus, results conclusively demonstrated successful masking of taste and oral disintegration of the formulated tablets in the oral cavity with improved dissolution.
