A comparative study of the in vitro permeation of ibuprofen in mammalian skin, the PAMPA model and silicone membrane [PDF]

open access: yes, 2016
Human skin remains the membrane of choice when conducting in vitro studies to determine dermal penetration of active pharmaceutical ingredients or xenobiotics. However there are ethical and safety issues associated with obtaining human tissue.

An investigation of some factors affecting transdermal permeation

open access: yes, 1985
Factors affecting transdermal permeation were investigated using Differential Thermal Anlaysis (DTA) and in vitro penetration studies of neonatal rat stratum corneum (s.c.), with radiolabelled propanol and hexanol as penetrants. Thermogravimetric Analysis, Thin-Layer Chromatography (TLC) and Infrared Spectroscopy were used to provide additional ...

Penetration enhancement effects of topically applied crosslinked hyaluronic acid

open access: yesInternational Journal of Cosmetic Science, EarlyView.
Cross‐linked hyaluronic acid (HA) was demonstrated to enhance the topical delivery of a variety of hydrophilic actives into the skin. This phenomenon was observed for both small molecules and macromolecules, the latter of which was analysed with MALDI mass spectrometry imaging (MALDI‐MSI).

Rationalising polymer selection for supersaturated film forming systems produced by an aerosol spray for the transdermal delivery of methylphenidate [PDF]

open access: yes, 2017
Film forming systems offer a number of advantages for topical and transdermal drug delivery, in particular enabling production of a supersaturated state which can greatly improve drug absorption and bioavailability.

Pharmacokinetics of Topical Administration of Altrenogest in Mares and Implications for Human Health

open access: yesJournal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Altrenogest is a synthetic progestogen widely used in equine reproductive management. Adverse effects to altrenogest have been reported in people with cutaneous exposure reported as the highest exposure pathway. Despite these reports, there has been no quantitative research to determine the capacity for altrenogest to be absorbed through skin.
