Abstract
In the present study, umbelliferone - phospholipids complex - loaded matrix film (UPLC – MF) was developed with a goal of improving transdermal permeation and anti-inflammatory potential of umbelliferone (UMB). Umbelliferone – phospholipids complex (UPLC) was prepared using solvent evaporation method. UPLC-MF was prepared by simple and reproducible solvent casting method. Prepared UPLC and UPLC-MF were both physico-chemically characterized by Fourier transforms infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), powder x-ray diffraction (PXRD), proton nuclear magnetic resonance spectroscopy (1H NMR), weight variation, thickness, tensile strength, folding endurance, % elongation, moisture content and uptake Functional characterization of UPLC and UPLC-MF was carried out by solubility analysis, in vitro dissolution, diffusion, and ex vivo permeation via dialysis and biological membrane. UPLC – MF was also evaluated for in vivo anti-inflammatory activity using carrageenan-induced Albino rat paw model. Design-based optimal values for formulation and process variables of UPLC were observed to be 1:1.78, 50 °C and 2 h, respectively. Physico-chemical characterization confirmed the formation of the complex and the film. UPLC demonstrated a higher aqueous solubility (~11-fold), compared to pure UMB. Rate and extent of dissolution of UMB from UPLC was enhanced significantly to that of pure UMB. Compared to UMB-MF, the diffusion and permeation rate of UMB from UPLC-MF enhanced significantly. The UPLC – MF improved the anti-inflammatory potential of UMB by significant enhancement of edema inhibition (%), compared to UMB-MF. The obtained results showed that the present combined formulation system could be employed as a promising strategy for improving transdermal permeation of UMB.
