Octyl methoxycinnamate is one of the ingredients in sunscreen products. The main aim of this study was to investigate the effect of different enhancers of in vitro skin permeability of Octyl methoxycinnamate. Octyl methoxycinnamate permeability parameters were evaluated through the whole skin of the rat with and without chemical enhancers including eucalyptus oil, urea, menthol and olive ...

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...

The transdermal route of administration offers an alternative pathway for systemic drug delivery with numerous advantages over conventional routes. Regrettably, the stratum corneum forms a formidable barrier that hinders the percutaneous penetration of most drugs, offering an important protection mechanism to the organism against entrance of possible dangerous exogenous molecules. Different typ...

The aim of the present investigation was to investigate the effect of chemical enhancers on the release of glipizide through transdermal matrix patch using different ratio of different chemical enhancers. L-menthol, oleic acid and n-octanol were tried over the glipizide matrix patch. The used concentrations of L-menthol and oleic acid were 1%, 1.5% and 2.0% and concentration of n-octanol was 1%...

TRANSDERMAL AND TRANSBUCCAL DELIVERY OF LIDOCAINE AND NICOTINE: COMBINED EFFECTS OF IONTOPHORESIS AND CHEMICAL ENHANCERS by Ran Wei This study focused on the effects of iontophoresis and chemical enhancers on drug release. The transport of Lidocaine HCl (LHCl) and Nicotine Hydrogen Tartrate (NHT) through the skin and mucosa was evaluated for potential clinical applications. These two potential ...

A series of drug-in-adhesive transdermal drug delivery systems (patch) with different chemical penetration enhancers were designed to deliver drug through the skin as a site of application. The objective of our effort was to study the influence of various chemical penetration enhancers on skin permeation rate and adhesion properties of a transdermal drug delivery system using Box-Behnken experi...

Adeno-associated virus (AAV) is a promising vector for human gene therapy. Although more effective than non-viral vectors, AAV still requires improvement in efficacy in order to become a successful gene therapy vector. With this in mind, we have sought to identify and examine identified enhancers of adeno-associated virus type 2 (AAV2) transduction. Using a high throughput screening system with...

conclusions the most effective enhancer for aha and ha were liquid paraffin and glycerol, respectively. the most effective surfactant for both aha and ha was tween 80. the effects of the enhancers were increased by prolonging the exposure time. results after 1.5 and 12 hours, the maximum permeated amount of aha were 89.8 and 342.5 mg, respectively, which related to the formulations with liquid ...

This paper reviews recent fi ndings about three skin penetration pathways (including a “polar pathway”) and four types of penetration enhancers (enzymes, vesicular systems, ceramides and chemical enhancers). This article will review possible ways for compounds to penetrate the skin and interact with it. Four families of enhancers will be discussed, along with their possible mechanisms of action...
