Development and Evaluation of Artemether Taste Masked Rapid Disintegrating Tablets with Improved Dissolution Using Solid Dispersion Technique

Research Article

Abstract

The purpose of this research was to mask the intensely bitter taste of artemether (ARM) and to formulate a rapid-disintegrating tablet (RDT) of the taste-masked drug. Taste masking was done by solid dispersion with mono amino glycyrrhyzinate pentahydrate (GLY) by solvent evaporation method. To characterize and formulate taste masked rapid disintegrating tablets (RDTs) of ARM, the 1:1M solid dispersion was selected based on bitterness score. Fourier transform infrared spectroscopy (FTIR), differential scanning calorimetry (DSC), and X-ray powder diffraction (XRPD) were performed to identify the physicochemical interaction between drug and carrier, hence its effect on dissolution. RDTs were evaluated for weight variation, disintegration time, hardness and friability. In vitro drug release studies were performed for RDTs at pH 1.2 and 6.8. Bitterness score was evaluated using mini-column method and compared with gustatory sensation test. FTIR spectroscopy and DSC showed no interaction while XRPD showed amorphization of ARM in GLY solid dispersion. RDTs prepared using solid dispersion, (RDT3), showed faster disintegration (within 28 s) and complete bitter taste masking of ARM. In addition, RDT3 exhibited better dissolution profile at both pH 1.2 and 6.8, than RDTs prepared from pure ARM (RDT5). Taste evaluation of RDTs in human volunteers rated tasteless with a score of 0 to RDT3 and 3 to RDT5. Mini-column revealed that RDT5 showed increase in number of persons who sensed bitterness with increased amount of ARM release while RDT3 sensed no bitterness. Thus, results conclusively demonstrated successful masking of taste and rapid disintegration of the formulated tablets in the oral cavity with improved dissolution.
