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 ...

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.

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.

Characterization of Ternary Solid Dispersions of Itraconazole, PEG 6000, and HPMC 2910 E5
Journal of Pharmaceutical Sciences, 2008In order to reduce the crystallinity of PEG 6000, blends were prepared by spray drying and extrusion with the following polymers; PVP K25, PVPVA 64, and HPMC 2910 E5. The maximal reduction of crystallinity in PEG 6000 was obtained by co-spray drying with HPMC 2910 E5. In the next step the model drug Itraconazole was added to the blend and the resulting

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 ...

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.
