Ibuprofen-polyethylene glycol (PEG) conjugates (PEG-Ibu) were prepared and their potential as a prolonged release system was investigated. Two PEG-Ibu conjugates were synthesized from Ibuprofen and PEG with two different molecular weights by esterification in the presence of DCC and DMAP. The PEG-Ibu conjugates were characterized by FT-IR, (1)H NMR, Mass spectroscopy and DSC analysis. The solub...

Immune thrombocytopenic purpura (ITP) is a life-threatening complication following pegylated interferon alpha (PEG-IFN) plus ribavirin treatment, the standard treatment for hepatitis C virus (HCV) infection. We reported a rare case with late-onset ITP after withdrawal of PEG-IFN treatment.A 53-year-old male with hepatitis C developed massive gum bleeding and a severe, reversible, immune thrombo...

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, ...

An alkalophilic bacterium, Bacillus cereus produced an extracellular alkaline protease, which was found to be active at high temperature and pH range, suitable for commercial laundry detergents. B. cereus protease was partitioned in different aqueous two-phase systems such as PEG/dextran, PEG/potassium phosphate, PEG/sodium citrate, PEG/magnesium sulphate and PEG/sodium dihydrogen phosphate and...

−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...

Background: A major challenge in downstream processing is the separation and purification of a target biomolecule from the fermentation broth which is a cocktail of various biomolecules as impurities. Aqueous two phase system (ATPS) can address this issue to a great extent so that the separation and partial purification of a target biomolecule can be integrated into a single step. In the food i...
