Design, Development and Characterization of Mouth Dissolving Tablet of Antivirals

Abstract: Objective: The main objective of this research work was to design, develop and characterization of mouth dissolving tablet of antivirals. Method: In this study, mouth dissolving tablet was prepared by direct compression method by using natural karaya gum, and synthetic sodium starch glycolate as Superdisintegrants in various concentrations. The designed tablets were subjected to various assessments parameters like hardness test, friability test, in vitro disintegration time, wetting time, in vitro drug release, and drug content. Result: All the ready formulations were subjected to various assessments parameters, and the findings obtain within the approved limit. A1-A9 containing karaya gum, and sodium starch glycolate in various concentrations demonstrate the minimum disintegration time. Among all these formulations A9 shows disintegration time u pto 15±1s due to the high concentration of superdisintegrants. In vitro drug release was tested in 0.1N HCl at a time interval of 0,2,4,6,8,10,12,14,16 min. The A9 shows drug release 99.4%. Accelerated stability study of optimized formulation (A9) up to 3 mo showed there was no change in disintegration time and percentage drug release. Conclusion: The results found in the present research work clearly showed a positive possible of mouth dissolving tablets containing a specific ratio of karaya gum and sodium starch glycolate as superdisintegrants.
