Objective(s) The aim of this study was to investigate the possibility of production of ibuprofen pellets with high amount of rate retarding polymer by aid of PEG400 as plasticizer. Materials and Methods Polyethylene glycol (PEG400) in concentrations of 1, 3 or 5% w/w with respect to Eudragit RL was used in production of pellets containing 60% ibuprofen and 40% excipient (2% polyvinylpyrrolid...

in this study, the effects of various hydrophilic (hpmc and carbopol 971) and plastic (ethylcellulose and eudragit rl100) polymers on the release profile of diltiazem hcl from matrix tablets were evaluated in-vitro. for this purpose, tablets containing 60 mg of diltiazem hcl along with various amounts of the aforementioned polymers were prepared using the wet granulation technique. tablets prep...

The main objective of this study was to prepare colon-specific pellets of budesonide, using pectin as film coating. Pellet cores of budesonide were prepared by extrusion / spheronization technique. Pectin, in different ratios was combined with Eudragit RS30D, Eudragit NE30D or Surelease to produce film coating. The dissolution profiles of pectin coated pellets were investigated in pH of 1.2 (2 ...

   The aim of the present study was to develop a single unit, site-specific matrix tablets of aceclofenac allowing targeted drug release in the colon with a microbially degradable polymeric carrier, chondroitin suphate (CS) and to coat the optimized batches with a pH dependent polymeric. The tablets were prepared by wet granulation method using starch mucilage as a binding agent and HPMC K-100 ...

a box-behnken design with three replicates was used for preparation and evaluation of eudragit vancomycin (vcm) nanoparticles prepared by double emulsion. the purpose of this work was to optimize vcm nanoparticles to improve the physicochemical properties. nanoparticles were formed by using w1/o/w2 double-emulsion solvent evaporation method using eudragit rs as a retardant material. full factor...

Abstract Here, we report the results of experiments regarding chemical repositioning 4‐(2‐hydroxyethyl)‐1‐piperazine ethane sulfonic acid ( HEPES ), a representative buffering agent. In this work, confirmed that could disaggregate amyloid plaques, hallmark Alzheimer's disease, and verified its sustained‐release system (release for up to 2 weeks) via hybridization with biocompatible polymer (Eud...
