The objective of the current study was to explore the use of different suppository bases i.e. Cocoa butter and different grades of polyethylene glycol bases (4000 and 6000) and to observe the effect of plasticizers incorporated in the suppositories for the successful delivery of Zaltoprofen, an novel non steroidal anti inflammatory drug through rectal route of administration. Moreover, Zaltopro...

PURPOSE To determine trends in utilization and off-label use of polyethylene glycol (PEG) 4000 in children and to determine the prevalence of constipation. METHODS Retrospective cross-sectional analyses were conducted from 1997 to 2007 in a French health care database comprising general practitioners and pediatricians. Patients prescribed PEG 4000 (Forlax(®); Ipsen Pharma, Paris, France) were...

The Leuconostoc species require sucrose in the culture medium as an inducer for the elaboration of glucosyltransferase (GTF) and glucans. Among all the reported putification methods, polyethylene glycol (PEG) is a effective and single step purification method for GTF from Leuconostoc mesenteroides. The extracellular GTFs from Leuconostoc mesenteroides L.m.28 and mutant Leuconostoc mesenteroides...

In this study, the primary paper-mill sludge characterized as containing 51% glucan was used to optimize enzymatic saccharification process for production of bioethanol using a Box–Behnken design (BBD). Polyethylene glycol 4000 (PEG-4000) surfactant-assisted dried (DPS) showed 12.8% improvement in efficiency. There statistically significant effect solid enzyme loading and time on DPS at 95% con...

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...

This study was designed to evaluate the effect of drag reducer polymers (DRP) on arteries from normotensive (Wistar) and spontaneously hypertensive rats (SHR). Polyethylene glycol (PEG 4000 at 5000 ppm) was perfused in the tail arterial bed with (E+) and without endothelium (E-) from male, adult Wistar (N = 14) and SHR (N = 13) animals under basal conditions (constant flow at 2.5 mL/min). In th...

Mango peel is a good source of protease but remains an industrial waste. This study focuses on the optimization of polyethylene glycol (PEG)/dextran-based aqueous two-phase system (ATPS) to purify serine protease from mango peel. The activity of serine protease in different phase systems was studied and then the possible relationship between the purification variables, namely polyethylene glyco...

Calcification is a frequent cause of the clinical failure of bioprosthetic heart valves fabricated from glutaraldehyde pretreated bovine pericardium (GATBP). An investigation was made of the grafting of different molecular weight polyethylene glycol (PEG 600, 1500, 4000 and 6000) via glutaraldehyde (GA) linkages to bovine pericardium (BP) and of their stability and calcification. The process of...

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 ...
