Enhancing Dissolution of Ibuprofen via Solid Dispersion Using Hydrophilic Carrier and Fast Dissolving Sugars

Al-Mustansiriyah Journal of Pharmaceutical Sciences, 2014
In this study, solid dispersion using hydrophilic carriers (polyethylene glycols) and fast dissolving sugars (sorbitol and lactose) has been employed to enhance dissolution and hence the bioavailability of ibuprofen.

NMR Characterization of Polyethylene Glycol Conjugates for Nanoparticle Functionalization

ACS Omega, 2023
The molecular weight, purity, and functionalization of polyethylene glycols are often characterized by 1H NMR spectroscopy. Oft-forgotten, the typical 1H NMR pulse sequence is not 13C decoupled. Hence, for large polymers, the 13C coupled 1H peaks arising

Polyethylene Glycol (PEG-3350, Colyte) Poisoning due to Intra-Peritoneal Leakage in an Elderly Patient [PDF]

Korean Journal of Critical Care Medicine
Polyethylene glycol (PEG)-3350 is the most frequently used lavage solution for bowel cleansing prior to colonoscopy or elective surgery because its large molecular weight means that it is poorly absorbed.

New Synthesis Route for PHD Polyols [PDF]

, 2011
The synthesis of polyurea dispersion polyols (PHD) was developed using a new route via depolymerization of polyurethane polyureas by a mixture of at least two glycols in the presence of a consumable catalyst, i. e. a secondary aliphatic amine.
