Leishmaniasis is a neglected tropical disease that requires timely and inexpensive treatment. For this purpose, nanoemulsion with polyene macrolide antibiotic, or amphotericin B (NE-AmB), was developed. This study quantified the amount of drug permeated retained in intact lacerated human skin, simulating cutaneous leishmaniasis (CL) processes. Toxicity macrophage keratinocyte cell lines, activi...

Objective(s): Folate-targeted liposomes have been well considered in folate receptor (FR) overexpressing cells including MCF-7 and 4T1 cells in vitro and in vivo. The objective of this study is to design an optimum folate targeted liposomal formulations which show the best liposome cell uptake to tumor cells.Material and Methods: In this study, we prepared and characterized different targ...

the purpose of this work was to study the effect of various permeation enhancers on the permeation of salbutamol sulphate (ss) buccal patches through buccal mucosa in order to improve the bioavailability by avoiding the first pass metabolism in the liver and possibly in the gut wall and also achieve a better therapeutic effect. the influence of various permeation enhancers, such as dimethyl sul...

The available minoxidil formulations for topical application suffer with major drawback and requires repeated application. The present study was aimed to investigate the effect of microemulsions and microemulsion based hydrogel-systems (MEHs) for increased percutaneous penetration of minoxidil. Minoxidil microemulsions were developed by conventional titration method using oleic-acid as oil, twe...

We describe a novel mechanism for vital fluorescent dye entry into sensory cells and neurons: permeation through ion channels. In addition to the slow conventional uptake of styryl dyes by endocytosis, small styryl dyes such as FM1-43 rapidly and specifically label hair cells in the inner ear by entering through open mechanotransduction channels. This labeling can be blocked by pharmacological ...

Worldwide prevalence of type 2 diabetes is increasing with alarming proportions. Metformin is the first-line oral antidiabetic drug of choice for the treatment of type 2 diabetes. The objectives of the present study were to develop Metformin solid lipid nanoparticles (M-SLN) and incorporate it in the transdermal patches. M-SLN was evaluated for Particle size, Zeta potential, Surface morphology ...

Chronic inflammatory skin diseases such as psoriasis have a significant impact on society. Currently, the major topical treatments have many side effects, making their continued use in patients difficult. Microalgae have emerged as a source of bio-active molecules such as glycolipids with potent anti-inflammatory properties. We aimed to investigate the effects of a glycolipid (MGMG-A) and a gly...

OBJECTIVE The purpose of this study was to improve skin permeation of evodiamine and rutaecarpine for transdermal delivery with microemulsion as vehicle and investigate real-time cutaneous absorption of the drugs via in vivo microdialysis. METHODS Pseudoternary phase diagrams were constructed to evaluate microemulsion regions with various surfactants and cosurfactants. Nine formulations of oi...

Tumor necrosis factor (TNF-α) and nitric oxide (NO) are important vasoactive mediators of septic shock. This study used a well-characterized quantitative permeation method to examine the effect of TNF-α and NO on systemic vascular barrier function in vivo, without confounding endotoxemia, hypotension, or organ damage. Our results showed 1) TNF-α reversibly increased albumin permeation in the sy...
