Nonionic surfactant vesicles (niosomes) were formulated with an aim of enhancing the oral bioavailability of tenofovir disoproxil fumarate (TDF), an anti-HIV drug. Niosomes were formulated by conventional thin film hydration technique with different molar ratios of surfactant, cholesterol, and dicetyl phosphate. The formulated niosomes were found spherical in shape, ranging from 2.95 μm to 10.9...

The current investigation aims to evaluate the transdermal potential of niosomes bearing a potent non-steroidal anti-inflammatory, piroxicam. Piroxicam-loaded niosomes were prepared and characterized for surface morphology, entrapment efficiency and in vitro permeation across excised rat skin from various proniosome gel formulations using Franz diffusion cells. Various non-ionic surfactants wer...

During the past decade formulation of vesicles as a tool to improve drug delivery, has created a lot of interest amongst the scientist working in the area of drug delivery systems. Vesicular system such as liposomes, niosomes, transferosomes, pharmacosomes and ethosomes provide an alternative to improve the drug delivery. Niosomes play an important role owing to their nonionic properties, in su...

Nonionic surfactant based vesicles (niosomes) are novel drug delivery systems formed from the self-assembly of nonionic amphiphiles in aqueous media. In the present study niosomal formulations of Paclitaxel (PCT), an antineoplastic agent, were prepared using different surfactants (Tween 20, 60, Span 20, 40, 60, Brij 76, 78, 72) by film hydration method. PCT was successfully entrapped in all of ...

Drug delivery systems using colloidal particulate carriers such as liposomes and niosomes have distinct advantages over conventional dosage forms. However, there remain significant problems like instability in the general application of liposomes and niosomes for drug delivery. Proniosome have the potential to become a promising drug carrier in order to give stability to niosomal drug delivery ...

meenakshikanwar(at)yahoo.com Abstract Over the past several years, treatment of infectious diseases and immunization has undergone a paradigm shift. Stemming from the nanobiotechnology research, not only a large number of disease-specific biologicals have been developed, but also enormous efforts have been made to effectively deliver these biologicals. Niosomes are vesicular systems prepared fr...

To prepare niosomes containing rifampicin were prepared using various nonionic surfactants of sorbitan ester class and cholesterol in 50:60 (1:1.2) percent mol fraction ratios for sustain release. To improve the dissolution rate of noisome are prepare handshaking method using Surfactants and cholesterol (150 μmol) in 50:60 (1:1.2) percent mol fraction ratio. The percent of drug estimated to be ...

Inflammatory processes play a crucial role in cardiovascular injury and disease. Inflamed endothelial cells express adhesion molecules which are potential therapeutic delivery targets for reducing or disrupting inflammation. We have developed non-ionic surfactant vesicles (niosomes) that are specifically targeted to inflamed vascular cells. Niosomes are self assembly vesicles that can encapsula...

We have previously reported a new preparation method for liposomes using supercritical carbon dioxide (scCO2) as a solvent, referred to as the supercritical carbon dioxide reverse phase evaporation (scRPE) method. In our previous work, addition of ethanol to scCO2 as a co-solvent was needed, because lipid molecules had to be dissolved in scCO2 to form liposomes. In this new study, niosomes (non...

Clotrimazole, an imidazole derivative antifungal agent is widely used for the treatment of mycotic infections of the genitourinary tract. In order to develop alternative formulation for the vaginal administration of clotrimazole to provide sustained and controlled release of appropriate drug for local vaginal therapy, liposomes/niosomes were evaluated as delivery vehicles. To optimize the prepa...
