N2 - Inflammatory skin diseases are typically managed with semi-solid formulations such as creams and ointments. These treatments often fail to remain on the skin for long, as they can be easily wiped off by clothing, necessitating frequent reapplication throughout the day and resulting in poor patient adherence. Therefore, this study sought to fabricate an electrospun dressing as an alternative dosage form that provides a sustained release of the anti-inflammatory agent tofacitinib over three days. In this study, three types of electrospun fiber dressings – uniaxial, coaxial, and layer-by-layer – were produced and examined for their morphological, mechanical, and release characteristics. In addition to a comprehensive characterization, another objective was to analyze the drug permeation behavior from these fiber dressings on porcine skin, comparing their performance to that of a tofacitinib cream. The layer-by-layer system notably exhibited a delayed drug release, while the uniaxial and coaxial systems demonstrated an initial burst release. However, the permeation studies revealed no significant differences between these systems, underscoring the necessity of conducting such studies – a crucial aspect often overlooked in research on electrospun fiber dressings. Overall, this study highlights the potential of electrospun, drug-loaded dressings for the treatment of inflammatory skin diseases.
