The present study was taken to formulate and evaluate mucilage obtained from Buchanania lanzan spreng seeds (BL) belonging to family anacardiacea for oral mucoadhesive drug delivery system containing losartan potassium. Physiochemical characteristics of mucilage, such as swelling index, microbial count, viscosity, hydration capacity, flow property, and pH were studied. The mucilage was evaluated for its mucoadhesive properties in compressed tablet, containing losartan potassium. Granules were prepared by wet granulation process using polyvinylpyrrolidone as binding agent. Mucilage was used in four different concentrations i.e., 21, 42 and 55% w/w. The tablet were prepared and evaluated for its physical property. Further, in vitro dissolution and swelling index was determined. The property of bioadhesive strength of isolated mucilage was compared with Guar gum and HPMC E5LV, which was used as standard mucoadhesive agent concentration. Bioadhesive strength of the tablet was measured on the modified physical balance. Result revealed that tablets had good physiochemical properties, and drug release was retarded as concentration of mucilage was increased. The force of adhesion was obtained 0.1238N, 0.2822N, 0.5175N, 0.8679N and 0.3983N respectively for F1, F2, F3, F4 and F5. Formulations were subjected for study the effect of agitation at different rpm. Formulation showed relative effect on release of drug from formulation. All the formulations were subjected to stability studies for three months, all formulations showed stability with respect to release pattern. In conclusions, these results indicate that the seed mucilage of BL can be a suitable excipient for oral mucoadhesive drug delivery systems.
