Abstract

Topical management of oral infection requires combined use of multiple classes of drugs and frequent dosing due to low drug retention rates. The sustained, co-delivery of drugs with different solubilities to cells using nanoparticle drug delivery systems remains a challenge. Here, we developed wheat germ agglutinin (WGA) conjugated liposomes with surface grafted cyclodextrin (WGA-liposome-CD) as bioadhesive dual-drug nanocarriers. We effectively encapsulated two physiochemically different drugs (ciprofloxacin and betamethasone) and demonstrated sustained co-drug release in saliva over a 24 h period in vitro. As proof of therapeutic utility in oral cells, we infected oral keratinocytes with Aggregatibacter actinomycetemcomitans, a bacterial pathogen responsible for chronic periodontal disease. Drug release, resulting from nanocarrier cell binding, produced a significant increase in oral cell survival and synergistically reduced inflammation. These results suggest that WGA-liposome-CD nanocarriers are novel cyto-adhesive candidates for delivering multiple drugs with sustained therapeutic activity for localized drug delivery to oral cells.
