The purpose of this research was to formulate and evaluate sustained release tablet by using novel polymer Remusatia vivipara tubers mucilage. Currently natural gums and mucilages are being used extensively comparable to synthetic drug release modifiers. Natural plant materials possess various advantages. These are very cheap, biocompatible, biodegradable and free from side effects. In present research Metoprolol succinate matrix tablets were prepared by using Remusatia vivipara tubers mucilage. For the formulation of sustained release matrix tablets, direct compression method was used. The formulated matrix tablets were then evaluated for thickness, diameter, hardness, weight variation, friability, drug content, swelling index, in-vitro drug release and stability studies. The formulated sustained release tablet passed all tests required. The dissolution profile of prepared tablets showed sustained release of drug up to 11 hours compared to the reference tablet formulation PROLOMET XI 100. Drug release data were then fitted in to release kinetic models such as zero order kinetic, first order kinetic, Higuchi model and Korsmeyer-Peppas model to study the release pattern of drug from each formulation. The prepared sustained release tablet formulation was compared with marketed formulation (reference formulation) for drug release study and factor f1 (difference factor) and f2 (similarity factor) were determined. From this study it can be concluded that as the concentration of Remusatia vivipara mucilage increases, there is decrease in the rate of drug release from the formulation. The best formulation was found to be F3 which consists of 20% Remusatia vivipara mucilage but did not give comparable drug release profile to the reference formulation with factor f1 69.4 % and f2 34.8%. But it can be said that Remusatia vivipara gum mucilage can be used in tablet formulation to give sustained release effect up to 10 hours or in combination with other natural gum mucilage it may enhance the release retardant effect of drug up to or more than 20 hrs. The release kinetic study showed that the prepared sustained release tablet formulation shows anomalous (non-fickian) diffusion pattern and follows both diffusion controlled and swelling controlled mechanisms for drug release.
