Healthcare-associated infections (HAIs) are a concern for health service providers, exacerbated by poor delivery of antimicrobials to target sites within the skin. The dermal route is attractive for local and systemic delivery of drugs, however; permeation, penetration, and access to deeper skin layers are restricted due to the barrier function of the stratum corneum (SC). Solid lipid nanoparticles present several benefits for topical delivery for therapeutic applications, especially via the follicular route. Hair follicles, surrounded by a close network of blood capillaries and dendritic cells, are an important target for delivery of antimicrobials and present a unique microbial nidus for endogenous infections in situations where the barrier is disrupted, such as after surgery, for example, triclosan, a broad-spectrum antimicrobial agent, was encapsulated into nanoparticles using glyceryl behenate and glyceryl palmitostearate (GP) solid lipids, and incorporating Transcutol P, a known permeation enhancer at different ratios. Optimised formulation was stable over 90 d and in vitro permeation studies using full thickness porcine ear skin showed that the lipid-based nanoparticles enhanced delivery of triclosan into the skin and could direct the agent towards hair follicles, indicating their potential as a carrier system for antiseptic dermal delivery.
