The main objective of developing any new dosage form is reduce the side effects and increase the therapeutic effect of drug i n existing dose of dosage form. Mucoadhesive drug delivery system is oral dos age form, where the tablet, gel or patch is attached to the buccal region for direct absorption of drug into blood circulation. This route can prevent the metabolism of drug in G.I tract or liver and side effects of metabolites avoided. In this study, the attempt was made to prepare mucoadhesive buccal tablets of Terbutaline sulphate with natural polymer sodium alginate with one side absorption by backing layer with ethyl cellulose. The buccal tablets of Te rbutaline sulphate studied in detail. I R Spectroscopy did the compatible study between polymers and Terbutaline sulphate and No interaction was found between drug and polymers . Different formulations of oral Mucoadhesive buccal tablets of Terbutaline Sulp hate (TS) were prepared using polymer sodium alginate, in different concentrations by direct compression. Post compressed evaluation studies, hardness, thickness, friability; weight variation and drug content, mucoadhesive strength of tablets were studied . The in - vitro release of TS was studied in buffer pH 6.8 at 37 0 C. All parameters of TS buccal tablets are passed the standard of mucoadhesive buccal tablets. It was found that mucoadhesive natural polymers exhibited better adhesiveness and mucoadhesive ness. The in vitro study of TS exhibited greater drug release profile with release of in the range of 79 . 25 to 99.85 %. |
