Abstract


Mucoadhesive is a bioadhesive dosage form which forms abond with mucous membranes.Mucoadhesive dosage forms stayed on mucous membranes in prolonged time so can increase bioavailability. This study intended to determine the effect of sodium alginate asbioadhesivepolymerto mucoadhesive strength of granules. The granules prepared usingamoxicillin asactive agent and sodium alginate as bioadhesivepolymer by wet granulation method. Granule evaluation are moisture content,particle size, wash off test using rat stomach and dissolution test. Test results of particle size distribution in the range of 1410-1680 µm, moisture content  from 11.07 to 13.57%, wash off test of F1, F2, F3, F4 and F5 as consecutively12.67, 14.00, 18.67, 26.00 and 33.33%. 2-way ANOVA test to% dissolution and wash-off test results sig. <0.05, so there is a significant difference between formulas. The results showed that increasing concentration of sodium alginate increase mucoadhesive strength of granules, the best formula is F3 that containing sodium alginate 580 mg.
