Abstract

The present invention was aimed to formulate and evaluate Lafutidine gastro retentive films. The films were prepared by solvent casting technique using different film forming polymers like HPMC and Ethyl cellulose. PEG 400 used as a plastsizer. The prepared films were evaluated for number of parameters like Physical appearance, Weight variation, Thickness, Folding endurance, Tensile strength, unfolding behavior, floating properties, drug content and In vitro drug release studies. From the trial batches the best release for gastroretentive film was shown by formulation T5 (Ethyl cellulose and PEG 400). Formulation T5 exhibited good appearance, better mechanical strength with acceptable flexibility. Also, formulation T5 was given more than 90 % drug released after 12 hr and 97.56 % Drug content.  For optimization of formulation, 32 factorial design was applied by taking Ethyl cellulose and PEG 400 as an independent variables. Drug release at 8 hour and folding endurance selected as dependent variables. Based on drug release study, L8 batch found most satisfactory in all formulation and the effect of Ethyl cellulose and PEG 400 found significant. L8 batch found stable during stability study.
Key words: Lafutidine, Floating Films, Ethyl Cellulose.
