Aim: This work aimed to develop a mucoadhesive film composed of a triblock copolymer (poloxamer 407), polyvinyl alcohol and polyvinylpyrrolidone for buccal modified delivery of metronidazole. Materials & methods: Three film formulations containing different polymer amounts were prepared by solvent casting. They were characterized as physicochemical, mechanical and mucoadhesive properties, and in vitro metronidazole release profiles. Results: Films displayed physicochemical, mechanical and mucoadhesive characteristics dependent of polymeric composition and drug presence. They could rapidly swell and promote the fast drug release (80% in 20 min) that was governed by Fickian diffusion. The films showed total disintegration in less than 90 s and total drug release in 30 min. Conclusion: Therefore, the formulations represent a promising alternative for modifying of buccal metronidazole delivery for pharmaceutical applications.
