Abstract

Developing innovative approaches to target osteomyelitis caused by polymicrobial infections remains a significant therapeutic challenge. In this study, monodispersed chitosan nanoparticles co-loaded with antibacterial (minocycline) and antifungal (voriconazole) agents were successfully prepared. Minocycline presented higher encapsulation efficiency as compared to voriconazole. Thermostability analysis suggested interactions between the co-loaded drugs within the dual-delivery system, potentially limiting voriconazole release. The dual-loaded chitosan nanoparticles exhibited significant in vitro anti-biofilm activity, achieving up to a 90% reduction in polymicrobial biofilms of S. aureus and C. albicans. Additionally, the nanoparticles showed cytocompatibility with a human osteoblast cell line. These findings highlight the potential of this dual-delivery chitosan-based nanoparticle system to address a critical gap in osteomyelitis treatment by targeting both bacterial and fungal pathogens.

期刊介绍： The International Journal of Pharmaceutics is the third most cited journal in the "Pharmacy & Pharmacology" category out of 366 journals, being the true home for pharmaceutical scientists concerned with the physical, chemical and biological properties of devices and delivery systems for drugs, vaccines and biologicals, including their design, manufacture and evaluation. This includes evaluation of the properties of drugs, excipients such as surfactants and polymers and novel materials. The journal has special sections on pharmaceutical nanotechnology and personalized medicines, and publishes research papers, reviews, commentaries and letters to the editor as well as special issues.
