Purpose: The aim of the work was to prepare nitrendipne-loaded Eudragit RL 100 microspheres to achieve sustained release nitrendipine. Method: Nitrendipne-loaded Eudragit RL 100 microspheres were prepared by an emulsion-solvent evaporation method using ethanol/liquid paraffin system. The resultant microspheres were evaluated for average particle size, drug loading, in vitro drug release and rel...

Abstract: Introduction: The purpose of the present study was to design, develop, and characterize transdermal patches containing Simvastatin for management blood lipid levels. Materials Methods: Transdermal were prepared by solvent casting method. evaluated physicochemical characteristics such as thickness, weight variation, folding endurance, percentage moisture uptake, content, drug ex-vivo p...

BACKGROUND AND THE PURPOSE OF THE STUDY The potential of pectin as a bacterially degradable polysaccharide for colon drug delivery has been demonstrated. Due to the high solubility and swelling properties of pectin in aqueous media, it is frequently used in combination with water insoluble polymers for targeting drugs to the colon. The aim of this study was to evaluate free films containing pec...

Alginate vehicles are capable of forming a gel matrix in situ when they come into contact with gastric medium in the presence of calcium ions. However, the gel structure is pH dependent and can break after gastric emptying, leading to dose dumping. The aim of this work was to develop modified in situ gelling alginate formulations capable of sustaining dextromethorphan release throughout the gas...

Ofloxacin is a synthetic chemotherapeutic antibiotic used for treatment of a variety of bacterial infections, but therapy suffers from low patients' compliance due to its unpleasant taste. This study was aimed to develop taste masked microspheres of ofloxacin using Eudragit and to prepare orodispersible tablets of the formulated microspheres using natural superdisintegrant. Taste masking Eudrag...

The multiparticulate formulation of sodium para aminosalicylate for oral administration was developed by extrusion spheronization technique. Microcrystalline cellulose was used as filler in concentration of 14.4% w/w. Pellets were coated with Eudragit L 30 D-55 using fluidized bed processor. Different weight gains of acrylic polymer were applied onto the pellets and evaluated for in vitro disso...

Sustained-release of buspirone HCl (BUH) was attempted by spray drying after dissolving in two commercially available aqueous polymeric dispersions (Eudragit RS 30 D or Kollicoat SR 30 D) at five different drug:polymer ratios (1:1, 1:2, 1:3, 1:6 and 1:9). The produced spray-dried agglomerates were evaluated in terms of their particle size and morphology, production yield, encapsulation efficien...

rivastigmine hydrogen tartrate (rht), one of the potential cholinesterase inhibitors, has received great attention as a new drug candidate for the treatment of alzheimer's disease. however, the bioavailability of rht from the conventional pharmaceutical forms is low because of the presence of the blood brain barrier. the main aim of the present study was to prepare positively charged eudragit r...

objective(s): a box-behnken design was used for evaluation of eudragit coated diclofenac pellets. the purpose of this work was to optimize diclofenac pellets to improve the physicochemical properties using experimental design. materials and methods: diclofenac was loaded onto the non-pareil beads using conventional coating pan. film coating of pellets was done at the same pan. the effect of pla...
