An infrared spectrophotometric method of estimating polyethylene glycol 4000.
In studies of intestinal absorption non-absorbed markers are used to indicate changes in volume of the contents of the bowel. Polyethylene glycol 4000 (PEG 4000), a popular marker, has been shown to fulfil the criteria of a volume indicator (Hyden, 1956b; Jacobson, Bondy, Broitman, and Fordtran, 1963; Maddrey, Serebro, Marcus, and Iber, 1967; Shields, Harris, and Davies, 1968). The concentratio...
متن کاملPolyethylene Glycol 3350 With Electrolytes Versus Polyethylene Glycol 4000 for Constipation: A Randomized, Controlled Trial
OBJECTIVE The long-term efficacy and safety of polyethylene glycol (PEG) in constipated children are unknown, and a head-to-head comparison of the different PEG formulations is lacking. We aimed to investigate noninferiority of PEG3350 with electrolytes (PEG3350 + E) compared to PEG4000 without electrolytes (PEG4000). METHODS In this double-blind trial, children aged 0.5 to 16 years with cons...
متن کاملPolyethylene glycol 4000 for treatment of functional constipation in children.
OBJECTIVES The aim of the study was to evaluate the effectiveness and safety of 2 different polyethylene glycol (PEG) doses for the maintenance treatment of functional constipation in children. METHODS Children with functional constipation according to the Rome III criteria were randomly assigned to receive PEG 4000 at a dose of either 0.7 g/kg (high-dose group; n = 45) or 0.3 g/kg (low-dose ...
متن کاملPreparation and characterization of gliclazide-polyethylene glycol 4000 solid dispersions.
The objective of the present investigation was to study the effect of polyethylene glycol 4000 (PEG 4000) on in vitro dissolution of gliclazide from solid dispersions. Initial studies were carried out using physical mixtures of the drug and carrier. Solid dispersions were prepared by the melting or fusion method.Phase and saturation solubility study, in vitro dissolution of pure drug, physical ...
متن کاملPreparation of Fe3O4Spherical Nanoporous Particles Facilitated by Polyethylene Glycol 4000
Much interest has been attracted to the magnetic materials with porous structure because of their unique properties and potential applications. In this report, Fe3O4nanoporous particles assembled from small Fe3O4nanoparticles have been prepared by thermal decomposition of iron acetylacetonate in the presence of polyethylene glycol 4000. The size of the spherical nanoporous particles is 100-200 ...
