Abstract

Mucoadhesive patches containing diclofenac sodium were prepared for the inflammatory treatment in periodontal disease. The present study formulated and evaluated the characteristics of the formulated diclofenac sodium patch. Three formulation (A1, A2, A3) of the patch were prepared by varying the concentrations of hydroxy propyl methyl cellulose (HPMC) solution, 1%, 1.5%., 2 %, respectively. Patches were prepared by solvent casting method. In vitro residence time showed that all formulated patches were attached on the mucosa gingival bovine more than 7 hours. Cumulative diffusion of diclofenac sodium at sixth hours from A1, A2 and A3 were 34%, 21 % and 24%, respectively. Backing layer formed from ethyl cellulose can inhibit diffusion of diclofenac sodium as much as 97.5%. From these result, diclofenac sodium patch containing 1% HPMC exhibited the best property.
