The enantiomeric separation of basic drugs was successfully demonstrated by using a novel chiral microemulsion electrokinetic chromatography (MEEKC). An interesting finding was that the chiral oil core ((S)-(+)-2-octanol) within the microemulsion droplets appeared to play an important role in the chiral separation mechanism. In addition, the enantioselectivity of the analyte-selector complex co...

Ondansetron HCl delivery through oral route suffers due to its low bioavailability due to first-pass metabolism. Therefore, the microemulsion-based transdermal delivery may be a better substitute for it. The pseudoternary phase diagrams were constructed to determine compositions of microemulsions, and ondansetron HCl microemulsions for transdermal delivery were developed using isopropyl myrista...

Nanoemulsions have small droplet size and are kinetically stable colloidal systems. These the thermodynamically isotropic system in which two immiscible liquids mixed to form a single phase by means of appropriate surfactant cosurfactant. Nanoemulsion sizes fall typically range 20–200 nm shows narrow distribution. They enhanced functional properties comparison conventional emulsions. The compos...

Nanoemulsions (NE) are isotropic, dispersions of oil, water, surfactant(s) and cosurfactant(s). A range components (11 surfactants, nine cosurfactants, five oils) were investigated as potential excipients for preparation ketorolac tromethamine (KT) ocular nanoemulsion. Diol cosurfactants the effect their carbon chain length dielectric constant (DEC), Log P, HLB on saturation solubility KT. Hen’...

the paper is focused on the formation of hydroxyapatite nanoparticles (hap) in polyelectrolyte-modified microemulsions, in a microemulsion template phase consisting of cyclohexane, water, cationic surfactant and cosurfactant, in the presence of na-polyacrylate (paa) as an anionic polyelectrolyte. it is shown that paa, can be incorporated into the individual inverse microemulsion droplets. the m...

A dispersed nano-system with droplet sizes as small submicrons is called a nanoemulsion. Nanoemulsions are thermodynamically stable, transparent, isotropic liquid mixtures of oil, water, surfactant, and co-surfactant. Nanoemulsion typically has between 20 200 nanometer. The size composition the scattered particles in continuous phase primary distinctions an emulsion This approach intended to al...

In this work, we report synthesis of superparamagnetic iron oxide nanoparticles at room temperature using microemulsion template phase consisting of cyclohexane, water, cetyltrimethylammonium bromide CTAB as cationic surfactant and butanol as a cosurfactant. Silica surface modification of the as prepared nanoparticles was performed by adding tetraethoxysilane TEOS to alkaline medium. The struct...

barrier to the permeation of most drugs, and especially as a hydrophobic barrier against hydrophilic drugs and ionized drugs. One possible means of facilitating the transdermal delivery of ionic drugs is through ion-pair formation. Oppositely charged ions can interact to form new species known as ion-pairs. This association reduces or neutralizes electrostatic charges and consequently reduces t...

BACKGROUND Akebia saponin D (ASD) exerts various pharmacological activities but with poor oral bioavailability. In this study, a self-nanoemulsifying drug delivery system (SNEDDS) based on the drug-phospholipid complex technique was developed to improve the oral absorption of ASD. METHODS ASD-phospholipid complex (APC) was prepared using a solvent-evaporation method and characterized by infra...
