Characterization of pullulan patches containing verapamil (Vera@pullulan) and Vera@CLCMP patches. A Photographs of the Vera@CLCMP and swelling ratio depending on adding amount of citric acid. B SEM micrographs of the freeze-dried samples of 5–25 wt% citric acid and 10 wt% glycerol. Scale bar, 100 μm. (C) FT-IR spectra of pullulan, CLCMP, verapamil, Vera@pullulan, and Vera@CLCMP. D Thermogravimetric analysis (TGA) curves and (E) Differential scanning calorimeter (DSC) thermograms of pullulan, CLCMP, verapamil, Vera@pullulan, and Vera@CLCMP. F In vitro accumulated free verapamil release from Vera@pullulan and Vera@CLCMP patch in PBS at 37 °C. G, H Full range of X-ray photoelectron spectroscopy (XPS) spectra of CLCMP and XPS spectra of C-C/C-H, O=C-O and C-O of CMP and CLCMP. Data is shown as mean ± SEM
