FORMULATION AND EVALUATION OF FAST DISSOLVING BUCCAL FILMS OF DIMENHYDRINATE

The aim of the present study was to develop a fast dissolving buccal film of dimenhydrinate with good mechanical properties and fast disintegration, producing an acceptable taste when placed in the mouth. The formulations were developed by solvent casting method by using HPMC E5 and HPMC E15 as film formers in different concentrations, propylene glycol as plasticizer and Poloxamer 407 as solubiliser. The resultant films were evaluated for various parameters. the films were found to be satisfactory for all the parameters. All formulations released more than 85% of the drug within 15 minutes. Formulation F7 (1% HPMC E5: 1% HPMC E15) was selected as the optimized formulation based upon the least disintegration time (24.3sec), optimum mechanical properties, percentage drug content (94.96%) and in vitro drug release (95.20%). The ex vivo release was found to be acceptable. Stability studies revealed that the formulation was stable on storage for two months.
