摘要: Abstract A new formulation for topical administration of drugs in the oral cavity has been developed using several film-forming and mucoadhesive polymers. The films have evaluated terms swelling, mucoadhesion organoleptic characteristics. best film, containing polyvinylpyrrolidone (PVP) as polymer carboxymethylcellulose sodium salt (NaCMC) polymer, was loaded with ibuprofen a model compound vitro vivo release studies were performed. Statistical investigation revealed that diffusion process main drug mechanism Higuchi's provided fit. In showed presence saliva (range 70–210 μg/ml) 5 h no irritation observed. These formulations offer many advantages comparison to traditional treatments can be proposed therapeutic tool against dental buccal diseases disturbs.
