Methods: The mucoadhesive buccal films of methylene blue were prepared by solvent casting technique using maltodextrin and pullulan at different ratios. Mechanical properties and disintegration time of the films were evaluated and sample sizes were chosen as described in pharmacopeias.

Results: After statistical evaluation using student"s t test, it is found that polymer type and concentrations affected both of the disintegration time and mechanical properties (p<0.05). The disintegration time of all the prepared formulations were less than 180 sec. and all formulations showed moderate mechanical strength (0.110 ± 0.034 to 0.783 ± 0.128 kgf ).

Conclusions: From the experimental data of our study it can be concluded that optimized formulations of MB loaded buccal films can be an adjunct to the therapy to complete eradication of the diseases in future. Keywords : Methylene Blue, Buccal Film, Pullulan, Maltodextrin, Propylene Glycol
