BACKGROUND Since barrier protection measures to avoid contact with allergens are being increasingly developed, we assessed the clinical efficacy and tolerability of a topical nasal microemulsion made of glycerol esters in patients with allergic rhinitis. METHODS Randomized, controlled, double-blind, parallel group, multicentre, multinational clinical trial in which adult patients with allergi...

Treatment of Psoriasis Abstract Mycophenolate mofetil (MMF), the morpholinoethyl ester of mycophenolic acid is an immunosuppressive agent used to prevent organ rejection after kidney and heart transplant. The drug seem to be effective in dermal diseases mainly psoriasis. However, till date it can be only be administered using systemic route which is often associated with side effects such as na...

Background: Since barrier protection measures to avoid contact with allergens are being increasingly developed, we assessed the clinical efficacy and tolerability of a topical nasal microemulsion made of glycerol esters in patients with allergic rhinitis. Methods: Randomized, controlled, double-blind, parallel group, multicentre, multinational clinical trial in which adult patients with allergi...

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...

INTRODUCTION Punica granatum is apotent source of polyphenolic compounds with strong free radicals scavenging activity. The skin lightening effects of Punica granatum are assumed due to ellagic acid which acts by chelating copper at the active site of tyrosinase. AIM To explore a topical microemulsion (O/W) of pomegranate (Punica granatum) extract for its control on skin erythema and melanin....

BACKGROUND The increased incidence of inflammatory diseases has necessitated the need to search for new topical dosage form of dexamethasone. OBJECTIVES The purpose of the present study was the preparation and evaluation of novel microemulsion as a topical delivery system for dexamethasone by mixing appropriate amount of surfactant including Tween 80 and Labrasol, cosurfactant such as capryol...

Curcumin was found to be beneficial in treating several skin pathologies and diseases, providing antioxidant protection due to its reducing properties and its electrophilic properties (the ability to activate the Nrf2 pathway and induce phase II cytoprotective enzymes). Nevertheless, clinical applications of curcumin are being hampered by its insufficient solubility, chemical instability, and p...

The purpose of this study was to investigate microemulsions as delivery systems for diclofenac sodium (DS). Microemulsion systems were composed of: soybean oil, nonionic surfactants (Brij 58 and Span 80), and different alcohols: ethanol, and 1-buthanol as cosurfactant. The optimum surfactant: cosurfactant (S:CoS) weight ratios and microemulsion areas were detected by the aid of ternary phase di...

Topical microemulsion systems for the antiacne agent, nadifloxacin were designed and developed to overcome the problems associated with the cutaneous delivery due to poor water solubility. The solubility of nadifloxacin in oils, surfactants and cosurfactants was evaluated to screen the components of the microemulsion. Various surfactants and cosurfactants were screened for their ability to emul...

Microemulsions improve the transdermal delivery of several drugs over conventional topical preparations such as emulsions and gels: enhanced drug solubilization, increased skin flux, decreased diffusion coefficient. Microemulsion-based systems find significant improvement in antifungals. We believe that drug-loaded microemulsion will show better antifungal activity by penetration into fungal ce...
