Special Issue Information
Dear Colleagues,
In the era of generative artificial intelligence (AI), which was welcomed by certain drug regulatory agencies, it is reasonable to expect accelerated implementation of all research innovations. Ranging from innovative pharmaceutical formulations (often being nanostructured) to sophisticated physico-chemical, thermal, imaging ,or analytical characterization techniques, even more conservative regulators could be convinced to implement certain changes in the existing guidelines and processes. Currently, a formulation’s nano/microstructure can be fully characterized using a smart set of complementary techniques. However, availability and equivalence testing often rely on human volunteers and/or excised human skin. On one hand, studies with clinical endpoints are faced with well-known assessment challenges. On the other hand, excised human skin introduces a number of variabilities (loss of physiological functions; donor-, storage-, or handling-related artifacts; etc.). Reputable research groups place great effort into developing skin models, such as reconstructed human epidermis (RHE), full-thickness models, and advanced 3D bioprinted constructs. Although they require further improvement in order to serve as true substitutes for human skin, their human-relevant biology, customizability to certain diseases, and compatibility with imaging and analytics offer rapid screening. Finally, upon robust validation, in silico models are continually improved to better support in vitro data, thereby aiming to reduce and potentially replace the need for human volunteers.
This Special Issue aims to encourage researchers to publish their findings in the field of topical and transdermal drug delivery systems. This Special Issue could enhance the available body of data for scientific justification of regulatory-driven skin formulation development.
We look forward to receiving your contributions.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Pharmaceutics is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
