Using the casting method novel mucoad hesive polymer blend film consisting of Carbopol, poloxamer, and hydroxypropylmethylcellulose (HPMC) was prepared and characterized. Triamcinolone acetonide (TAA) was loaded into Carbopol/poloxamer/HPMC polymer blend flm.Carbonyl band of Carbopol in Carbopol/poloxamer/HPMC shifted to longer wavenumber than that of Carbopol in Carbopol/poloxamer due to the hydrogen bonding among Carbopol, poloxamer, and HPMC. Tan ${\delta}$ peak assigned to glass transition temperature (Tg) of HPMC shifted to low temperature due to increased flexibility caused by increased poloxamer content in polymer blend films. Swelling ratio of Carbopol/poloxamer/HPMC films was lowest in Carbopol/poloxamer/HPMC at mixing ratio of 35/30/35 (wt/wt/wt). Adhesive force of Carbopol/poloxamer/HPMC films increased with increasing HPMC content in Carbopol/poloxamer/HPMC polymer blend film and increasing hydroxypropyl group content in HPMC due to hydrophobicproperty of HPMC although bioadhesive force was highest at mixing ratio of 35/30/35 (wt/wt/wt). Release of TAA from TAA-loaded Carbopol/poloxamer/HPMC polymer blend film in vitro increased with increasing loading content of drug.
