The objective of the present investigation was to develop a parenteral microemulsion delivering artemether, a hydrophobic antimalarial drug and to evaluate antimalarial activity of the microemulsion in comparison to the marketed oily injection of artemether (Larither(®)). The microemulsion was evaluated for various parameters such as globule size, ability to withstand centrifugation and freeze-...

Purpose: Diltiazem, a calcium ion cellular influx inhibitor is known for its limited and variable bioavailability. This study is intended to explore the benefits of microemulsion formulation as oral drug delivery system for immediate release to improve the bioavailability and efficacy of Diltiazem. Methods: Oil in water microemulsion was prepared using the simple water titration method. The opt...

Abstract Background Melatonin (MEL) is a powerful antioxidant molecule with anti-androgenic property. A microemulsion (ME) system loaded MEL was designed for treatment of androgenic alopecia. Pseudo-ternary phase diagram constructed, and ME formulae were developed using coconut oil, Tween 80 PEG 400. In the present study, characterized evaluated droplet size, polydispersity index, zeta potentia...

The goal of this study was to develop a parenteral microemulsion formulation of cyclosporine A (CyA). The CyA solubility in caprylic capric triglyceride (GTCC), ethyl oleate and soybean oil were determined. The pseudo-ternary diagrams of oil (GTCC), surfactant (Solutol® HS-15), cosurfactants (ethanol/polyethylene glycol 400 [PEG 400] mixture) and water were constructed to identify boundaries fo...

Solvation dynamics in a neat ionic liquid, 1-pentyl-3-methyl-imidazolium tetra-flouroborate ([pmim][BF4]) and its microemulsion in Triton X-100 (TX-100)/benzene is studied using femtosecond up-conversion. In both the neat ionic liquid and the microemulsion, the solvation dynamics is found to depend on excitation wavelength (lambda(ex)). The lambda(ex) dependence is attributed to structural hete...

PURPOSE The purpose of this study was to predict microemulsion structures by creating two artificial evolutionary neural networks (ANN) combined with a genetic algorithm. The first ANN would be able to determine the type of microemulsion from the desired composition, and the second to determine the type of microemulsion directly from a differential scanning calorimetry (DSC) curve. METHODS Th...

A novel functional KH₂PO₄ (KDP) aqueous solution-in-oil (KDP aq/O) microemulsion system for KDP crystal ultra-precision chemical-mechanical polishing (CMP) was prepared. The system, which consisted of decanol, Triton X-100, and KH₂PO₄ aqueous solution, was available at room temperature. The functional KDP aq/O microemulsion system was systematically studied and applied as polishing solution to ...

In this work, M-doped TiO2 nanostructures (M: Fe, Co and Ni) were synthesized by reverse microemulsion method. The as-prepared products were analyzed by different techniques such as scanning electron microscopy (SEM), Transmission electron microscopy (TEM), X-ray diffraction (XRD) and Fourier Transform Infrared Spectroscopy (FT-IR). The effect of various dopants (Fe, Co and Ni) on ba...

Purpose: Lovastatin is poorly water soluble drug. It should be come into the BCS II drug. So oral bioavailability of lovastatin is less (50%). To develop novel dosage foam of the self-microemulsifying drug delivery systems (SMEDDS) for the lovastatin. Methods: Before the formulation of SMEDDS, solubility study was performed in different exicipients and select exicipients on basis of solubility ...
