In this study, we investigated the effect of different permeation enhancers at different concentrations viz. oleic acid, olive oil and castor oil from transdermal gel for transdermal delivery of venlafaxine, a newer antidepressant. It is a first line drug in the treatment of depression and inhibits brain serotonin and norepinephrine neuronal reuptake. It is also used in the treatment of anxiety...

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 ...

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...

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...

Ion pairing is a strategy used to increase the permeation of topically applied ionised drugs. Formation occurs when electrostatic energy attraction between oppositely charged ions exceeds their mean thermal energy, making it possible for them draw together and attain critical distance. These then behave as neutral species, allowing partition more readily into lipid environment. Partition coeffi...

PURPOSE The objective of the study was to evaluate the synergistic transdermal permeation effect of chemical enhancers and iontophoresis technique on tolterodine tartrate (TT) transdermal gel and to evaluate its pharmacokinetic properties. MATERIALS AND METHODS Taguchi robust design was used for optimization of formulations. Skin permeation rates were evaluated using the Keshary-chein type di...
