Other Engineering Eudragiit Material ,100-55 With the exception of Eudragit L and Eudragit L 30 D, higher amounts of coating material were needed to achieve gastro-resistance with aqueous coating than with organic coating. Allergy and Immunology This work was aimed at the formulation and in vitro evaluation of a colon-targeted drug delivery system containing mebeverine HCl.

The effect of storage conditions on the release of drug from coated pellets was determined as a function of the pH of the dissolution medium.
The aim of the present study was to investigate the influence of Eudragit E PO on the drug release mechanism of Eudragit L film coatings applied to theophylline tablets by a dry powder coating technique. Absorptions of active principle and coated pharmacon have been determined by means of Sartorius Membrane transport tester.
To achieve these aims, yield, incorporation efficiency, particle size and the euudragit of microspheres were determined, and the influence of the inner phase viscosities prepared with different polymer and polymer mixtures on particle size and the distribution of microspheres were evaluated. Solubility of CoQ10 in different surfactant media was measured, and a suitable dissolution medium was developed to compare the dissolution patterns of the solid dispersion, physical mixture, and the pure compound.
Release performance of a poorly soluble drug from a novel, Eudragit-based multi-unit erosion matrix. The study was aimed to developed and investigate a novel polymer for intestinal drug delivery with improved mucoadhesive properties. The effects of changing the ratio of HPMC to anionic polymers were examined in water and in media with different pH.
Epub Mar 7. Poorly water-soluble weakly basic compounds which are solubilized in gastric fluid are likely to precipitate after the solution empties from the stomach into the small intestine, leading to a low oral bioavailability. Multi-unit controlled release systems of nifedipine and nifedipine: The immobilized thiol groups were preactivated by disulfide bond formation with 2-mercaptonicotinic acid.
