Abstract:
Conventional suppositories of tolmetin sodium were prepared by using two different types of Witepsol as an oily base and two different ratios of polyethylene glycol 400: polyethylene glycol 4000 as an water-soluble base. In addition, sustained- release suppositories were prepared by adding Eudragit L-100 ta the suppositories. The effects of the suppository base and the ratios of the polyethylene glycol 400: polyethylene glycols 4000 on the in vitro release characteristics were investigated. The release rate of tolmetin sodium from the conventional suppositories prepared with polyethylene glyco

Abstract:
1. Polyethylene glycol has been used extensively as a probe to measure passive small-intestinal permeability in viro. However, there has been some uncertainty as to its suitability for use as an indicator of the permeation of water-soluble molecules across the intestinal wall because it seems to traverse the mucosa in much greater quantities than sugar molecules of equivalent Mr. 2. We have measured the permeation of polyethylene glycol-400 and lactulose from aqueous solution across pure lipid solvents in vitro. We found considerable transport of polyethylene glycol-400 across chloroform (1.03

During the extraction of PEG 400, the polyethylene glycol solvates the Horg+ ion in the organic phase giving rise to the HLorg+ species (L is polyethylene glycol). The obtained value of the extraction constant Kex(HLorg+) = 933 is consistent with published data of metal extraction. Extraction of PEG 1 500 was treated applying

Another approach aimed to obtain liquid bio-polyols that could be suitable for producing rigid PU foams. For this purpose, oven-dried crude BA bark water extracts were liquefied with polyethylene glycol (PEG 400) at temperatures of 130-170°C.
