Étude des intéractions SR 33557/PEG 6000
Thermochimica Acta, 1994Resume Au cours de ce travail, nous nous sommes proposes d'etudier les interactions d'un principe actif: le SR 33557 et d'un excipient, le polyethylene glycol 6000. Le diagramme de phase a ete etabli pour les compositions de 3 a 97% en masse de PEG 6000.

PEG-6000 Assisted Growth of Copper Dendrites
Journal of Dispersion Science and Technology, 2010Highly uniform copper dendrites were successfully prepared in large quantities by a simple wet chemical approach using hydrazine hydrate as reducant in the presence of polyethylene glycol 6000 (PEG-6000) at room temperature. Scanning electron microscopy (SEM), ultraviolet (UV)-vis absorption spectroscopy, and x-ray diffraction (XRD) have been used to ...

Etude thermoanalytique et spectrale de l'interaction lorazepam/PEG 6000
Journal of Thermal Analysis and Calorimetry, 1995The solubility and rate of dissolution of a poorly-soluble active principle are of importance when substances are destined for oral administration. Physical blends in wich drug and carrier are able to form particular compositions, such as a eutectic, may exibit an increased rate of dissolution. In this work the interactions lorazepam and PEG 6000, were

Understanding processing-induced phase transformations in erythromycin–PEG 6000 solid dispersions
Journal of Pharmaceutical Sciences, 2006Since the quality and performance of a pharmaceutical solid formulation depend on solid state of the drug and excipients, a thorough investigation of potential processing-induced transformations (PITs) of the ingredients is required. In this study, the physical phenomena taking place during formulation of erythromycin (EM) dihydrate solid dispersions ...

In vitro and in vivo evaluation of carbamazepine-PEG 6000 solid dispersions
International Journal of Pharmaceutics, 2001The present work extended previous physico-chemical investigations on the effects of solid dispersion on the solubility, the dissolution rate and the pharmacokinetic profile of carbamazepine. Solubility studies showed a linear increase in carbamazepine solubility with the increase of PEG 6000 concentration.

Preparation, characterization and dissolution of ciprofloxacin/PEG 6000 binary systems
International Journal of Pharmaceutics, 1991Abstract Thermomicroscopy and DSC were employed to study ciprofloxacin/PEG 6000 binary systems in the form of solid dispersions and physical mixtures. The dissolution processes of ciprofloxacin from the binary systems and pure ciprofloxacin were also studied.

Solid-State NMR Investigation of Indomethacin−Cyclodextrin Complexes in PEG 6000 Carrier
Bioconjugate Chemistry, 2002Various solid dispersions of alpha-, beta- and gamma-cyclodextrin (CD) in PEG 6000 with and without the addition of 5% w/w indomethacin were prepared by the melting method using the original components. The samples were investigated by solid-state (13)C NMR, and the interactions between the drug and the cyclodextrins were evaluated.

Investigation of PEG 6000/Tween 80/Span 80/H2O niosome microstructure
Colloid and Polymer Science, 2007A stable niosome is prepared from Poly(ethylene glycol) [PEG] 6000/Tween 80/Span 80/H2O lamellar liquid crystal. The niosome structures and properties are studied by the methods of negative-staining transmission electron microscopy and small angle X-ray diffraction.

[Study on pilules of indomethacin--PEG 6000].
Yao xue xue bao = Acta pharmaceutica Sinica, 1992Indomethacin (IDM)-PEG 6000 pilules were prepared using PEG 6000 as the carrier. The solubility of IDM in IDM-PEG 6000 pilules was about twice as much as pure IDM. When the effective dose of IDM-PEG 6000 was only half that of IDM tablet, the irritation of IDM-PEG 6000 pilule on rat stomach was reduced significantly but it still manifested the action of

Drought Stress Tolerance in Wheat Using PEG 6000
This research evaluated the ability of five wheat types—K-9107, HD 2954, Raj-4125, HUW234, and NW-2036—to withstand limited water availability using a lab-based setup with PEG-6000 to mimic dry conditions at an osmotic level of -1.0 bars. As Triticum aestivum plays a key role in India's diet by supplying more than half of the population's energy and ...KOMAL +3 more
