In this study, hydrogels
containing 2-hydroxyethyl methacrylate
(HEMA), Eudragit L-100, and fusidic acid in different compositions
were prepared with the confinement method by using ammonium persulfate
(APS) as a chemical initiator and ethylene glycol dimethacrylate (EGDMA)
as a cross-linker to determine the most suitable formulation for use
in eczema treatment. Fusidic acid (FA)-confined pHEMA/Eudragit L-100 in synthesis of the hydrogel was used with the
Taguchi method, and the optimum synthesis conditions were determined.
The swelling percentages of the hydrogels were calculated in different
pH environments and distilled water. Also, the cream formulations
developed and contained in chitosan and HEMA-based polymers were synthesized.
Viscosity and pH values changed between 30,000 and 100,000 cP and
between 5 and 6 for different cream formulations with various conditions,
respectively. Also, swelling percentages of hydrogels were between
20 and 40. Fourier transform infrared spectroscopy (FTIR) and scanning
electron microscopy (SEM) analyses were performed to characterize
the hydrogel structure and the cream formulations. In addition, the
stability of the formulations to 28 days and the changes in parameters
such as appearance, centrifugation, pH, relative density, viscosity,
spreading were evaluated, comparatively.
