Formulation and evaluation of sitagliptin buccal patch

The aim of present work was to formulate and evaluate Sitagliptin buccal patch using solvent casting method. Buccal patch gained importance as it overcomes the limitations of current routes of administration, provides rapid onset of action by releasing drug directly to systemic circulation through oral mucosa by mucoadhesion. The formulated buccal patches were evaluated for various parameters like film thickness, surface pH, folding endurance, weight variation, % moisture loss, tensile strength, % elongation, drug content uniformity, and in vitro dissolution studies The optimized formulation (F4) containing HPMC E5 and Eudragit RL 100 polymer combination in 1:1 ratio showed highest in vitro dissolution (99.7 %) and satisfactory stability.
