Summary: This research investigated the potential of nail patches as topical treatments for onychomycosis. It found that the nature of the drug and adhesive influenced drug release and permeation through the nail plate. The patches, especially those containing Amorolfine HCl in Duro-Tak 202A, showed promising anti-fungal efficacy and residence on toenails for at least two weeks.

Summary: This study aimed to prepare Span 60-based elastic nanovesicles using the adapted ethanol injection method, and evaluate their ability to improve transdermal permeation of tacrolimus. Different concentrations and types of penetration enhancers were assessed for their impact on the physicochemical properties of the nanovesicles. The results showed significant enhancement in in vitro release compared to pure drug suspension.

Summary: Delivery of drugs via transdermal routes offers advantages, but overcoming the skin's barrier properties remains challenging. Chemical permeation enhancers (CPEs) can improve transdermal drug delivery, but may have side effects. With advancements in analytical techniques, synthetic chemistry, and combinatorial studies, CPEs-aided transdermal drug delivery is expected to reach its full potential.

Summary: This study investigates the feasibility of incorporating chemical penetration enhancers (PE) into lipid nanoparticles (LNPs) to improve the targeting of idebenone (IDE) to the skin. The results suggest that the use of a mixture of oleic acid and isopropyl myristate as PE can significantly increase IDE penetration into different skin layers. Additionally, IDE-loaded LNPs exhibit higher antioxidant activity compared to free IDE.

Summary: Skin pharmacokinetics (SPK) can explain the different effects of permeation enhancers on drug permeation at the kinetic level. SPK of permeation enhancers can be classified into lateral elimination and longitudinal elimination, and evaluated using the diffusion ratio (DRSC-EP). The linear relationship between parameters such as ke-enhancer and Delta Cmax-drug, MRTenhancer and Delta Tmax-drug, and AUCt-enhancer and Delta AUCt-drug suggests that SPK precisely controls drug permeation in vivo.

Summary: Bacterial nanocellulose-based nail patches with moisturizing capabilities and biocompatibility were developed to improve the local treatment of nail diseases. The addition of glycerol and urea enhanced hydration and facilitated the release and permeation of drugs and extracts. The antibacterial effects of the patches against relevant pathogens were also demonstrated.

Summary: Iontophoresis is a widely used drug delivery technique that has the potential to improve transungual nail delivery for nail diseases. Traditional treatments often result in relapses due to lower permeation, while iontophoresis offers efficacy and practicality for extended treatment periods.

Summary: The cutaneous delivery route is increasingly common for drug administration, with the use of chemical penetration enhancers (CPEs) to facilitate drug transport through skin layers. The creation of a CPE-DB database allows for the classification and identification of new enhancers, as well as the prediction of biological activity using machine-learning applications.

Summary: A validated HPLC method for quantifying efinaconazole in ex vivo human nail permeation study samples was developed and applied. The method showed good specificity and linearity in the concentration range of 50 to 10000 ng/mL. The study also demonstrated that Labarfac CC significantly increased the permeation of efinaconazole compared to other formulations.

Summary: This study aimed to investigate the loading of sildenafil citrate in three commercial transdermal vehicles using 3D full-thickness skin equivalent and compare the results with permeability experiments using porcine skin. The results showed that the results obtained using the 3D skin equivalent were comparable to those obtained using porcine skin, suggesting that the 3D skin model can be a valid alternative for ex-vivo skin absorption experiments.
