Abstract
A freely accessible database has recently been released that provides measurements available in the literature on human skin permeation data, known as the ‘Human Skin Database – HuskinDB’. Although this database is extremely useful for sourcing permeation data to help with toxicity and efficacy determination, it cannot be beneficial when wishing to consider unlisted, or novel compounds. This study undertakes analysis of the data from within HuskinDB to create a model that predicts permeation for any compound (within the range of properties used to create the model). Using permeability coefficient (Kp) data from within this resource, several models were established for Kp values for compounds of interest by varying the experimental parameters chosen and using standard physicochemical data. Multiple regression analysis facilitated creation of one particularly successful model to predict Kp through human skin based only on three chemical properties. The model transforms the dataset from simply a resource of information to a more beneficial model that can be used to replace permeation testing for a wide range of compounds.

[PMID: 36105622 PMCID: PMC9464638 DOI: 10.2147/ijn.s372711] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2022] [Accepted: 08/29/2022] [Indexed: 11/23/2022] Open
Abstract
Background The poor skin permeation and deposition of topical therapeutic drugs is a major issue in topical drug delivery, improving this issue is conducive to improving the topical therapeutic effect of drugs. Methods In this study, octadecylamine modified hyaluronic acid (OHA) copolymer was synthesized by amide reaction technique to prepare curcumin (CUR)-loaded micelles (CUR-M) for topical transdermal administration. CUR-M was successfully prepared by dialysis, and the formulation was evaluated for particle size, zeta potential, surface morphology, entrapment effciency (EE%), drug loading (DL), X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR) and the in vitro drug release. Additionally, in vitro skin permeation and retention, in vivo topical analgesic and anti-inflammatory activity, and skin irritation were assessed. Results The mean drug loading (DL), drug entrapment efficiency (EE), hydrodynamic diameter and zeta potential of CUR-M were 8.26%, 90.86%, 165.64 nm and −26.85 mV, respectively. CUR-M was characterized by X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR), it was found that there was an interaction between CUR and OHA, and CUR existed in CUR-M in an amorphous form. CUR-M exhibited sustained release in 48 h and good stability at 4 °C for 21days. CUR-M could significantly increase the skin penetration and retention of CUR and had better analgesic and anti-inflammatory activities in vivo when compared with CUR solution. Hematoxylin-eosin staining results revealed that the transdermal penetration mechanism of CUR-M might be related to the hydration of stratum corneum by HA. In addition, CUR-M showed no skin irritation to mouse skin. Conclusion CUR-M might be a promising and safe drug delivery system for the treatment of topical diseases.

Abstract
An important question in the development of a dermatological drug product is whether a target concentration has been achieved in, for example, the viable epidermis following topical administration. When attempting to address this challenge, it is essential to consider the role of excipients in the formulation that may influence drug partitioning and diffusion in the different layers of the skin. The objective, therefore, was to correlate, in human subjects, the skin pharmacokinetics of diclofenac (specifically, its uptake into and clearance from the stratum corneum (SC)) from an approved drug product (Voltaren® medicated plaster) with the in vivo co-uptake of two key excipients, namely propylene glycol and butylene glycol. SC sampling was used to assess diclofenac input into the skin during patch application, and its subsequent clearance post-removal of the delivery system. In parallel the uptake of the two glycol excipients was also measured. Drug and excipient amounts in the SC increased with time of application up to 6 h and, for diclofenac, no further increase was observed when the administration was prolonged to 12 h. When the plaster was removed after 6 h of wear, diclofenac cleared relatively slowly from the SC suggesting that drug binding with a slow off-rate had occurred. The results indicate that the optimisation of drug delivery from a topical formulation must take into account the disposition of key excipients and their impact on dermato-pharmacokinetics in general.
