FORMULATION AND EVALUATION OF MUCOADHESIVE BUCCAL PATCHES OF PIROXICAM

The main objective of present investigation to formulate and evaluate mucoadhesive buccal patches of Piroxicam, using solvent casting method. HPMC K100 M were used as a mucocoadhesive polymer and PEG 400 used as a plasticizer as well as penetration enhancers. The formulated patches of piroxicam were evaluated for their appearance, weight variation, thickness, folding endurance, surface pH, swelling index, drug content, % elongation, mucoadhesive strength, in vitro drug release, kinetic release study and stability study. Among all formulated batches (S1-S8) of buccl patches batch S6 showing maximum drug release after 8 hours 94.77 % and mucoadhesive strength 10.21±0.35g). The stability study optimized batch S6 doesn’t show any changes with respect to previous evaluation carried out before stability study. It may concluded the mucoadhesive buccal patches of Piroxicam were successfully prepared using HPMC K100 M by solvent casting method, evaluated & it is better alternative to conventional drug delivery for the management of pain and arthititis
