영문 초록

The purpose of this study is to prepare the adhesive type patch containing flurbiprofen, and to demonstrate the feasibility of flurbiprofen administration through the intact skin using adhesive type patch preparation. For this purpose, two pressure sensitive adhesives, Polyisobutylene(PIB) and Gelvan 737, were selected from the chemical grade of polymers, and the adhesive type patches of flurbiprofen were prepared. The release rate of flurbiprofen from the PIB-based adhesive patch was higher than that from Gelva 737 based adhesive patch. The release rate of flurbiprofen from the PIB-based A-type patch with 1.0mm, 1.5mm or 2.0mm thicknesses followed the first order kinetics. In the skin permeation study, using male hairless mouse skin, a monophasic skin permeation profile was observed with 1% flurbiprofen loading dose. The inclusion of palmitic acid or SLS(0.25~0.5%) as an enhancer produced a remarkable enhancement in the skin permeation rate of flurbiprofen, and the percentile ratio of drug and enhancer appeared to be important for the effective enhancement. In the in vivo percutaneous absorption study, the plasma concentration of the optimal formulation was significantly (p<0.01) higher than that of the conventional cataplasma(Bifen). These studies demonstrate a good feasibility of flurbiprofen administration through the intact skin using a transdermal patch, and show a possibility of the development of flurbiprofen patches.
