Concentrations of Fe, Mn, Cu, Zn, Ca, Mg, K, and P were examined in untreated and ion exchange resin-treated solutions of polyethylene glycol, molecular weight 3000 to 3700, polyethylene glycol (PEG 4000). Relatively high levels of P were found in untreated PEF-4000 solutions. The concentration of contaminating P in solutions prepared from untreated PEG 4000, even at high water potentials (-1 t...

The objective of the present study was to evaluate the effect of different plasticizers on the ethylcellulose coatings of capsules and its timed release characteristics. Various plasticizers such as dibutyl phthalate (DBP), triacetin (TA), glycerol, triethyl citrate (TEC), polyethylene glycol-4000 and polyethylene glycol-6000 (PEG) were studied. The physicochemical properties of the casted poly...

this study investigated the applicability of polyethylene glycol (peg-4000) coated fe3o4 magnetic nanoparticles for the selective removal of toxic pb (ii) ion from wastewater. the fe3o4 magnetic nanoparticles of 24 nm were synthesized using a coprecipitation method and characterized by scanning electron microscopy (sem), vibratingsample magnetometer (vsm), and x-ray diffraction (xrd). sem image...

In the present work, gliclazide loaded polyethylene glycol (PEG) based solid dispersions were prepared using fusion method in order to improve the solubility and dissolution rate of gliclazide. The compatibility of the drug with various formulation components was established. Solid dispersions (SDs) of gliclazide and polyethylene glycol (PEG 4000, 6000 and 8000) at three mass ratios (1:1, 1:3, ...

Polyethylene glycol (PEG) 4000 is one of numerous substances used as non-absorbable markers to correct for variable faecal output when assessing daily faecal losses of nutrients. The introduction of enteric coated micro-encapsulated pancreatic enzyme (EMPE) preparations has greatly improved the control of fat malabsorption in cystic fibrosis and chronic pancreatitis patients. Unfortunately, the...

This study aims to identify and analyze the band gap width of carbon phase produced from corncobs mixed with PEG-4000 see surface area corncob phase. First, characterization test was carried out using Scanning Electron Microscope Energy-Dispersive X-ray (SEM-EDX) spectroscopy determine morphology Ultraviolet–Visible (UV-Vis) carbon. Then, adding Polyethylene Glycol (PEG) 4000 at a specific conc...

Objective: The study aimed to solubilization of imidazole drugs of interest; ketoconazole (KT) and miconazole nitrate (MN), for enhancement of the water solubility, the dissolution properties and the antimycotic activity of these drugs. Method: Different solid dispersion methods were used to prepare various dispersion systems of KT and MN using polyethylene glycol 4000 (PEG 4000), polyethylene ...

−The purpose of this investigation was to enhance the dissolution rate of loratadine using polyethylene glycol 6000 (PEG) solid dispersions (SDs). The solubility behavior of loratadine in the presence of polyethylene glycol 4000 and polyethylene glycol 6000 in water showed linear increase with increasing concentrations of PEG, indicating AL type solubility diagrams. SDs of loratadine with PEG 6...

The purpose of this study is to fabricate the polyethylene glycol matrix tablet by mold technique. Indomethacin and hydroxypropylmethylcellulose were used as model drug and polymer, respectively, in PEG matrix system. The physical and drug release characteristics of developed matrix tablet were studied. This inert carrier system comprising 7:3 polyethylene glycol 4000: polyethylene glycol 400 c...

BACKGROUND AND AIMS Polyethylene glycol preparations (PEG) are increasingly used for chronic constipation in both adults and children. There are some suggestions that PEG 4000 with orange flavour (Forlax) tastes better than PEG 3350 which contains salt (Movicolon). Poor taste is an important factor for non-compliance and is one of the leading causes of therapy failure. The aim of the study was ...
