Recent developments in skin mimic systems to predict transdermal permeation.
In recent years there has been a drive to create experimental techniques that can facilitate the accurate and precise prediction of transdermal permeation without the use of in vivo studies. This review considers why permeation data is essential, provides a brief summary as to how skin acts as a natural barrier to permeation and discusses why in vivo studies are undesirable. This is followed by...
متن کاملPredicting skin permeability from complex chemical mixtures: dependency of quantitative structure permeation relationships on biology of skin model used.
Dermal absorption of topically applied chemicals usually occurs from complex chemical mixtures; yet, most attempts to quantitate dermal permeability use data collected from single chemical exposure in aqueous solutions. The focus of this research was to develop quantitative structure permeation relationships (QSPR) for predicting chemical absorption from mixtures through skin using two levels o...
متن کاملInfluence of Chemical Permeation Enhancers on the in vitro Skin Permeation of Minoxidil through Excised Rat Skin: A Mechanistic Study
Abstract: Minoxidil, a pyrimidine derivative (2, 4-diamino-6-piperidinopyrimidine-3-oxide) is the only topical medical treatment with proven efficacy for the treatment of Androgenetic alopecia that shown low skin penetration and bioavailability. The main aim of this research was to investigate the effect of some permeation enhancers on the in vitro skin permeability of minoxidil . Minoxid...
متن کاملSkin preparation and permeation experiments
First, excised human skin obtained from abdominal plastic surgery is prepared for storage. In this procedure, the subcutaneous fatty tissue is separated from the outer skin layers, namely the epidermis and the dermis by a scalpel. Second, the epidermis is separated from the underlying dermis by a heat-separation technique. The separated epidermis will be used for subsequent permeation experimen...
متن کاملPermeation models and structure-function relationships in ion channels.
Recent determination of the molecular structures of potassium andmechanosensitive channels from x-ray crystallography has led to arenewed interest in ion channels. The challenge for permeation modelsis to understand the functional properties of channels from the availablestructural information. Here we give a critical review of the three maincontenders, namely, continuum theories, Brownian dyna...
