Certain agents that enhance drug transport through the skin, including surfactants, bile salts, and fatty acids, have been shown to exert a similar effect on the oral mucosa. Oral drug delivery offers an attractive method of needle-free drug administration. Unfortunately, oral delivery is often hampered by the poor permeability of drugs across the intestinal epithelium. Although several single ...

gene therapy is in its development stage as a novel method for cancer treatment. liposomes look promising as gene delivery vectors; however, investigations have shown that these vesicles are not doing well in some cases. it was decided here to investigate the possibility of augmentation of liposomal gene delivery by chemical penetration enhancers.cationic liposome containing antisense oligonucl...

The effect of combination of PG with DMSO, BC, IPM, Tween 80 and SLS on drug release rate was studied in vitro. The mechanism of drug release was also studied by using power law. Significant difference (One way ANOVA; p<0.05) in release rate among the 16 formulations was seen in the study. The release profiles of various formulations also showed that the added enhancers in individual batches af...

Chemical penetration enhancers are often used to enhance transdermal drug delivery. However, the fundamental mechanisms that govern the interactions between penetration enhancers and skin are not fully understood. Therefore, the goal of this work was to identify naturally fluorescent penetration enhancers (FPEs) in order to utilize well-established fluorescence techniques to directly study the ...

Achieving a desirable percutaneous absorption of drug molecule is a major concern in formulating dermatological products. The use of penetration enhancers could provide a successful mean for this purpose. The aim of this study was to evaluate the effect of incorporating a few common penetration enhancers (in different concentrations) into a 0.5% w/w piroxicam (model drug) gel formulation, on th...
