Comparison of permeability of topical Cream drug through polymer synthetic membranes of different structures using Franz Cell diffusion test.

AbstractIn this study, in-vitro release experiments were performed using a Franz Diffusion Cell system for Terbinafine Hydrochloride, which is used in the treatment of various fungal infections in the skin caused by many susceptible dermatophytes. In order to evaluate TH transdermally, it was aimed to compare the permeability between polymeric membranes synthesized with polyvinyl alcohol and chitosan mixtures and commercial membranes. In the transdermal drug delivery system calculations, the Fick Diffusion Law was modified and the obtained data were compared. The study was evaluated according to the USP <1724> topical drug products in semisolid form - performance tests. A new high-performance liquid chromatography method was validated for the assay of TH released into the receptor medium in accordance with the ICH guideline. According to the results obtained during the validation process, the limit of detection value was calculated as 0.005 µg/mL and the limit of quantification value was 0.013 µg/mL. Since polymer-based synthetic membranes provide permeability according to molecular size, properties and the ideal environment for measuring and analyzing the diffusion rate of a compound, in experiments conducted using membranes of different structures, the permeability profiles of selected polymer synthetic membranes were statistically evaluated. It has been noted that the hydroxyl groups in PVA and the hydrophilic CS-g-PNDMAAm graft copolymer act at varying rates to enhance or reduce the permeability across the membrane by promoting its diffusion. NaY zeolite has been shown to function as an adsorbent against the medication, lessening the impact of hydrophilic PVA without supplying permeability. [ABSTRACT FROM AUTHOR]
