Instructions for Use

In the current study, possible mechanisms by which deformable liposomes and ethosomes improve skin delivery of ketotifen under non-occlusive conditions were investigated. In vitro permeation and skin deposition behavior of deformable liposomes and ethosomes, having ketotifen both inside and outside the vesicles (no sepn. of free ketotifen), having ketotifen only inside the vesicles (free ketotifen sepd.) and having ketotifen only outside the vesicles (ketotifen soln. added to empty vesicles), was studied using rabbit pinna skin. Results suggested that both the penetration enhancing effect and sildenafil 50mg tablet the intact vesicle permeation into the stratum corneum might play a role in improving skin delivery of drugs by deformable liposomes, under non-occlusive conditions, and that the penetration enhancing effect was of greater importance in case of ketotifen. Elasticity of vesicles assessed by electron spin resonance, electron microscopy and extrusion measurements. 2001, 217, 13– 24, DOI: 10.1016/S0378-5173(01)00576-2Google Scholar33Elasticity of vesicles assessed by electron spin resonance, electron microscopy and extrusion measurementsvan den Bergh, B. Fatty acid spin labels were incorporated into vesicles, composed of the single chain non-ionic surfactant octaoxyethylenelaurate-ester (PEG-8-L), the sucrose laurate-ester L-595 and cholesterol sulfate (CS) to monitor local dynamic properties of lipid mols. in vesicle bilayers and to study the elasticity of vesicle bilayers. Studies with the spin label probes 5-, 12- and 16-doxyl stearic acid (DSA) indicated that both the order parameter and the rotational correlation times increased when the doxyl group was positioned closer to the headgroup region. These findings indicate that the fluidity of membranes decreased near the headgroup region. Comparing 16-DSA incorporated in vesicle formulations with either 30 or 70 mol% showed no difference in alkyl chain mobility as was reflected by the order parameter. The rotational correlation times, however, showed a slowdown from 0.38 to 0.71 and 1.13 ns when the PEG-8-L molar content was decreased from 100 to 70 and 30 mol% for PEG-8-L:L-595:CS vesicles, resp. Extrusion measurements indicated an increase in elasticity of vesicle bilayers as the molar content of PEG-8-L was increased from 10 to 90 mol%. Incorporation of cholesterol sulfate stabilizes vesicles and thereby, decreases the elasticity. The increased elasticity correlated excellent with a redn. In conclusion, these results demonstrate that when the molar content of the single chain non-ionic surfactant PEG-8-L in vesicles is increased the elasticity is enhanced and the rotational correlation time is reduced. The enhanced elasticity might contribute to an optimal design of vesicles as drug carriers for transdermal application.

• Sildenafil gel clinical trials report variable efficacy across populations.
• Polymeric gels can enhance skin penetration of sildenafil.
• Storage at room temperature preserves gel stability and potency.
• Avoid sharing the gel to prevent contamination.
• Combining with vacuum erection devices may improve efficacy.
• The onset of action can be delayed if applied over non-intact skin.
• Using the gel immediately before intercourse yields the best results.

(Elsevier B.V.)Bilosomes represent an evolving vesicular carrier that have been explored for oral vaccines delivery based on its ability to resist enzymes and bile salts in the gastrointestinal tract (GIT). Bilosomes vesicles are formed of bilayer membrane of non-ionic surfactant mols.

Although, bilosomes have not been proposed for transdermal drug delivery, this carrier seems to have promising potential in this regard. Accordingly, the aim of this investigation was to assess the capability and safety of utilizing bilosomes for transdermal delivery of tenoxicam (TX) as a model drug.
