The influence of skin permeation enhancers, such as dimethyl sulphoxide (DMSO) and 1-[2-(decylthio)ethyl]azacyclopentan-2-one (HPE-101), Labrafac CC, Labrafil, Labrasol and Transcutol in a concentration of 10% (wt./wt.) on the formation of porphyrins in normal mouse skin from topical application of creams with methyl 5-aminolevulinate (MAL) was studied. The concentration of porphyrins in the mo...
The present study investigated the feasibility of ostrich oil utilizing as a promising vehicle for improved skin permeation of sinomenine with reference to vaseline matrix containing different content of chemical enhancers. The fatty acid composition of ostrich oil was analyzed by GC-MS. Penetration enhancing potential of ostrich oil on permeation of sinomenine across rat abdominal skin in vitr...
Dermal permeation through human epidermis and uptake into isolated human stratum corneum (SC) that was and was not delipidized were measured for 2 model compounds, 4-cyanophenol (CP) and methyl paraben (MP), from saturated aqueous solutions containing 1 or both compounds. Because the solutions were in equilibrium with the pure CP and MP, the thermodynamic activity of the compounds was constant....
The enhancing effect of ascorbic acid and triethyl citrate (TEC) on the in vitro skin permeation of rofecoxib across rat epidermis was investigated. Skin pre-treatment with ascorbic acid and TEC at different concentrations, followed by application of rofecoxib gel, showed higher permeation flux than the control condition. The mechanism underlying this permeation enhancement was probed with four...
background: cellulite is the accumulation of subcutaneous fat and connective tissue in tights and buttocks. xanthines, such as aminophylline, are used as phosphodiesterase inhibitors, and are also adenosine receptor antagonists. objectives: the aim of the present study was to characterize in vitro aminophylline transdermal absorption through shed snake skin, and to investigate the absorption en...
a suitable emulgel formulation of piroxicam was prepared and its percutaneous permeation was investigated using wistar rat skin and diffusion cell technique. the concentrations of the drug in receptor phase of diffusion cells were measured using hplc method. the effect of three types of penetration enhancers (myrj 52, cineol and transcutol p) with different concentrations on transdermal permeat...
In the past decade, many strategies have been developed to enhance oral drug delivery. Different techniques were investigated, amongst those the use of permeation enhancers such surfactants and biodegradable polymers were studied more extensively. Chitosan and its derivatives have been studied as permeation enhancer. The aim of the current study was to develop a nanoparticulate system based on ...
Curcumin is the active component of Curcuma species including C. longa (turmeric). This molecule is well known for its anti-inflammatory effect, which seems to be stronger than that of hydrocortisone. Curcuma species have been used in Asian traditional medicine as topical anti-inflammatory drugs. Curcumin has poor oral bioavailability and its topical application could be of choice, particularly...
In the past decade, many strategies have been developed to enhance oral drug delivery. Different techniques were investigated, amongst those the use of permeation enhancers such surfactants and biodegradable polymers were studied more extensively. Chitosan derivatives have been studied as permeation enhancer in free soluble form and as nanoparticulate systems. The aim of the current work wa...
