To overcome this drawback, the electrospray method was used to prepare Eudragit L nanoparticles with high drug loading capacity in one step. Enhanced bioavailability of a eudragig water-soluble weakly basic compound using a combination approach of solubilization agents and precipitation inhibitors: Effect of anionic l10055 on the release of propranolol hydrochloride from matrix tablets. Pharm Dev Technol Aug 30;16 4: 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.

Eur J Pharm Biopharm Sep 7;67 2: To achieve these aims, yield, incorporation efficiency, particle size and the distribution 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.

Pharmazie Apr;56 4: The aim of this work was to investigate the efficient targeting and delivery of indometacin INDas a model anti-inflammatory drug to the colon for treatment of inflammatory bowel disease. J Pharm Sci Mar 27; 3: Acta Pharm Hung May;60 Multi-unit controlled release systems of nifedipine and nifedipine: Previous attempts to improve the dissolution and absorption properties of itraconazole ITZ through advanced formulation design have focused only on release in acidic media; however, recent reports indicate that absorption occurs primarily in the proximal small intestine.

Polyethylene glycol PEG was used as primer to facilitate initial coating powder adhesion. The preparation of dipyridamole DIP alginate alg microspheres by different methods or the incorporation of tragacanth trghpectin or Eudragit L 55 Eud in alg microsphere formulations did not provide a prolonged release of DIP at pH 1.

Hot melt extrusion HME for amorphous solid dispersions: The fibers are found to have cylindrical morphologies with smooth surfaces, except at high drug loadings that appear to induce surface roughness PVP or l100-55 Eudragit. Targeted intestinal delivery of supersaturated itraconazole for improved oral absorption.

In their previous publications the authors rendered account of preparation and stability test of products containing controlled release nitrofurantoin in circumstances of preparing and storing. Drug Dev Ind Pharm Jan;28 1: In this study, a novel emulsion diffusion method was used to prepare enteric Eudragit L nanoparticles by ultrasonic dispersion and diffusion solidification. Powder coating, a water and organic solvent-free process, was investigated as a method to prevent the migration of an ionizable, highly water soluble model drug into the polymeric film during the coating process.

Farmaco Oct;58 Drug Dev Ind Pharm Mar;28 3: The purpose of this research was to improve the hygroscopicity and poor flow properties of the crude dry extract of the seeds of Glinus lotoides and improve the disintegration time of the core-tablets for enteric coated formulation thereof. To give relief from this intolerable toothache, doctors prescribe painkillers along with antibiotics. Solubility parameters calculations SPCsdifferential scanning calorimetry DSCand rheological analysis of drug-polymer physical mixtures PMs was performed.

Mechanisms governing the release of drugs from controlled delivery systems are mainly diffusion, osmosis and erosion. Dorothea Sauer James McGinity. The physical and chemical properties of propranolol hydrochloride and anionic polymer complex were investigated using Fourier transform infrared spectroscopy FTIR and differential scanning calorimetry DSC.

It is a solid substance in form of a white powder with a faint characteristic odour. Eur J Pharm Biopharm Jul;52 1: Mol Pharm Jul 10;12 7: Please contact us at webmaster matweb. Int J Pharm Feb 20; Epub Nov To allow cleaning of sebum ducts for acne prophylaxis the authors suggest use of triethanolamine buffered with anionic polymers of acrylic and methacrylic acid.

Poly methacylic acid-co-ethyl acrylate 1: Matrix tablets were prepared using ethyl cellulose ECEudragit RL either solely or in combination by wet granulation technique. Hygroscopicity, flow property and disintegration time were improved significantly due to the adsorption and granulation processes. For a drug with low bioavailability, a matrix tablet with liquid permeation enhancer Labrasol was formulated. Questions or comments about MatWeb?
