The purpose of this study was to prepare a novel paclitaxel (PTX) microemulsion containing a reduced amount of Cremophor EL (CrEL) which had similar pharmacokinetics and antitumor efficacy as the commercially available PTX injection, but a significantly reduced allergic effect due to the CrEL. The pharmacokinetics, biodistribution, in vivo antitumor activity and safety of PTX microemulsion was ...

We propose that one can deduce very insightful information regarding the drug and fatty acid binding capacity of microemulsions through simple turbidity experiments. Pluronic F127-based oil-in-water microemulsions of various compositions were synthesized and titrated to turbidity with concentrated amitriptyline, an antidepressant drug. We observed that, above certain Pluronic F127 concentration...

clopidogrel, an inhibitor of platelet aggregation, selectively inhibits the binding of adenosine diphosphate (adp) to its platelet receptor and the subsequent adp-mediated activation of the glycoprotein gpiib/iiia complex, thereby inhibiting platelet aggregation. oral bioavailability of clopidogrel is very low (less than 50%), due to its poor water solubility. the aim of this investigation was ...

BACKGROUND Tacrolimus and cyclosporine microemulsion are the 2 major immunosuppressants for heart transplantation. Several studies have compared these 2 drugs, but the outcomes were not consistent. This meta-analysis of randomized controlled trials compared the beneficial and harmful effects of tacrolimus and microemulsion cyclosporine for heart transplant recipients. METHODS Electronic datab...

BACKGROUND The aim of this study was to develop and characterize a babassu oil microemulsion system and determine the effect of this microemulsion on the functional activity of phagocytes. METHODS The microemulsion was formulated using distilled water, babassu as the oil phase component, Sorbitan monooleate-Span 80(®) (SP), Polysorbate 80-Tween 80(®) (TW), and 1-butanol (BT). Pseudoternary di...

BACKGROUND Compound Arnebiae radix oil has been clinically applied to treat burns and scalds for a long time. However, it is unstable and inconvenient to use. The aim of this study was to prepare a compound Arnebiae radix microemulsion gel for transdermal delivery system and evaluate its characteristics. MATERIALS AND METHODS Based on the solubility of Shikonin, the active component of Arnebi...

Clopidogrel, an inhibitor of platelet aggregation, selectively inhibits the binding of adenosine diphosphate (ADP) to its platelet receptor and the subsequent ADP-mediated activation of the glycoprotein GPIIb/IIIa complex, thereby inhibiting platelet aggregation. Oral bioavailability of clopidogrel is very low (less than 50%), due to its poor water solubility. The aim of this investigation was ...

OBJECTIVES The objective of this study was to find a stable microemulsion vehicle for transdermal delivery of ibuprofen to improve the skin permeability. MATERIALS AND METHODS Microemulsion was prepared using different sorts of oils, surfactants and co-surfactants. Pseudo-ternary phase diagrams were used to evaluate the microemulsion domain. The effects of oleic acid and surfactant mixture on...

der process and is strongly influenced by bile secretion, pancreatic exocrine secretion, food intake and gastrointestinal motility4. For this reason, many formulations have been proposed to improve the gastrointestinal absorption of cyclosporine A. In 1996, a cyclosporine A formulation in a microemulsion concentrate, containing a surfactant, lipophilic and hydrophilic solvents and an organic so...

In the present work, levofloxacin based microemulsion was developed and its usefulness as topical drug carrier system for anti bacterial activity was investigated. Microemulsion was prepared by phase titration method using oleic acid as oil phase, tween-60 as surfactant and isopropyl alcohol as co-surfactant. Five different formulations were formulated with various amount of the oil, water and ...
