| A metronidazole-loaded hydrogel was synthesized by free radical polymerization using dimethylaminoethyl methacrylate (DMAEMA) monomer and triethyleneglycol dimethacrylate (TEGDA) and methylene bisacrylamide (MBA) as cross-linkers. The DMAEMA hydrogels were cross-linked with 5 and 10% MBA or with 0.1, 0.5, 1 and 4% TEGDA as cross-linking agents. Ammonium persulfate and tetramethyl ethylene diamine were used as initiator and catalyst, respectively. The prepared hydrogels were characterized, and the effect of cross-linking agent content on the swelling behavior and in vitro drug release of hydrogels was investigated. The results of X-ray diffractometry, differential scanning calorimetry and Fourier transform infrared spectroscopy studies indicated that the prepared hydrogels possessed an amorphous morphology and there was not any interaction between the hydrogel polymers and metronidazole as drug, which resulted in the dependence of drug release on the physicochemical characteristics of hydrogel such as swelling, polymer erosion, and surface morphology. According to the results, the hydrogel containing 0.5% TEGDA which was prepared by freeze-drying method exhibited a porous structure with a high swelling ratio and displayed a sustained and complete drug release. It could be concluded that the hydrogel developed by this facile method is a good candidate with a potential for use in gastroretentive drug delivery systems. |
