Resumo(s)AIM: Caffeic acid has been described as active against bacteria commonly isolated from wound infections. However, its low stability and poor solubility reduce caffeic acid applicability as a pharmaceutical product. These parameters can be enhanced by complexation with cyclodextrin. The main goal of the present work was to incorporate caffeic acid on cyclodextrin-based hydrogels capable of controlled delivery, in order to be used as antibacterial wound dressing. MATERIALS & METHODS: Cyclodextrin-based hydrogels were prepared by direct crosslinking of -cyclodextrin or hydroxypropyl--cyclodextrin with 1,4-butanediol diglycidyl ether in the presence of hydroxypropyl methylcellulose. RESULTS: The hydrogels obtained combine good physicochemical properties (viscoelasticity, superabsorbency and high ability to retain and deliver caffeic acid) with the preservation of caffeic acid' antibacterial activity and effect on fibroblasts, with gel--cyclodextrin the most suited. CONCLUSION: The hydrogels obtained could be useful as caffeic acid delivery-system devices for the treatment of wound infections.
