Abstract
Objective: It was the aim of this study to evaluate the impact of nonionic and ionic surfactants on skin penetration of dexpanthenol.
Methods: The relative potency of three surfactants (two nonionic and one ionic) as enhancers in the permeability of a series of compounds was investigated. The influence of the enhancers was also studied. For this purpose, porcine abdominal skin was prepared and mounted on Franz diffusion cells, while different mixtures of Dexpanthenol containing Tween®85, SDS and Span®80 in concentrations of 0.5%, 1%, 2%, 5% (m/V) were evaluated in terms of their permeation enhancing effect. The amount of permeated drug was determined via HPLC analysis. Moreover, the cytotoxicity and skin irritating effect of the compounds were tested on Caco-2 cells.
Results: The cytotoxicity profile of Dexpanthenol showed no toxicity to the cells over 1 and 3 h of incubation. The permeation was evaluated over a time period of 180 min, whereas a ranking of SDS> Span>Tween could be determined as permeation enhancer.
Conclusion: Taking these findings into consideration, concentration of 1% (w/w) surfactant showed the most promising results. The increase in flux based on low concentrations of enhancer was ascribed to their ability to reduce skin´s barrier and improve drug permeation. The results showed that the nature of enhancer greatly impacts cutaneous barrier impairment.
Keywords: Cell culture, delivery, penetration, safety testing, skin barrier, surfactants.

Advancements in Robotic and AI-based Drug Discovery and Delivery for Neurological Disorders
Neurological disorders, including Alzheimer's disease, Parkinson's disease, epilepsy, and brain tumors, pose significant challenges in drug delivery due to the blood-brain barrier's intricate structure and the complexity of neuronal networks. Traditional drug delivery methods often fall short in reaching therapeutic concentrations within the central nervous system, limiting treatment efficacy and ...read more
Electrospun Fibers as Drug Delivery Systems
In recent years, electrospun fibers have attracted considerable attention as potential platforms for drug delivery due to their distinctive properties and adaptability. These fibers feature a notable surface area-to-volume ratio and can be intentionally designed with high porosity, facilitating an increased capacity for drug loading and rendering them suitable for ...read more
Nanoemulsions in cancer therapy
Solid tumors are characterized by leaky vascular structure, defective angiogenesis and high interstitial fluid load, providing opportunities for nanoparticles to preferentially exudate and be retained in tumors. This phenomenon is commonly referred to as the enhanced permeability and retention (EPR) effect, which is considered to be an important reason why ...read more
Nanotechnology Based Chemotherapy for the treatment of Head & Neck Cancer
The escalating recurrence rates observed in Head and Neck cancer, particularly within the chemo-therapeutically treated cohort (50-60%), can be attributed to the non-selective nature of current anticancer drug delivery modalities. In this context, nanotechnology-based drug delivery systems emerge as a promising avenue for achieving precise localization of therapeutic agents to ...read more
