Abstract

The purpose of this study was to investigate the physicochemical properties of nonpareil beads coated with Eudragit® RS 30 D containing ibuprofen as a multifunctional agent. The influence of the concentration of ibuprofen in the film coating and the effect of the coating level on drug release from coated beads was determined in pH 7.2 phosphate buffer solution. The influence of storage time at 23°C and 60°C on the release of ibuprofen from coated beads was also investigated. The thermal properties of the films were determined using a differential scanning calorimeter. Scanning electron microscopy was employed to image the surface morphology of the coated beads. Infrared spectroscopy was used to study the interaction of Eudragit RS 30 D and ibuprofen. Results from the dissolution studies demonstrated that increasing the amount of ibuprofen in the polymeric film reduced the rate of drug release, mainly because of a more complete coalescence of the polymeric particles of the latex dispersion. The glass transition temperature (Tg) of Eudragit RS 30 D films decreased and the surface of the coated beads became smoother as the concentration of ibuprofen was increased. Hydrogen bonding between the polymer and ibuprofen was demonstrated by Fourier transform infrared spectroscopy. No significant differences were found in drug dissolution between the coated beads stored at 23°C for 12 months and those stored at 60°C for 12 hours. The results of this study demonstrated that the ibuprofen plasticized the Eudragit RS 30 D. Furthermore, the dissolution rate of ibuprofen can be controlled and changes in the drug release rate can be minimized by using the drug-induced plasticization technique with this polymer.
