Intraoral Drug Delivery: Bridging the Gap Between Academic Research and Industrial Innovations

open access: yesAdvanced Functional Materials, EarlyView.
Intraoral drug delivery offers a promising route for systemic and localized therapies, yet challenges such as enzymatic degradation, limited permeability, and microbial interactions hinder efficacy. This figure highlights innovative strategies—mucoadhesive materials, enzyme inhibitors, and permeation enhancers—to overcome these barriers.
