A new formulation method was developed for preparing poly(D,L-lactic-co-glycolic acid) (PLGA) nanoparticles loaded with recombinant human granulocyte colony-stimulating factor (rhG-CSF). Lyophilized rhG-CSF powder and PLGA polymer were directly co-dissolved in a single organic phase, and the resulting solution was dispersed into an aqueous solution. PLGA nanoparticles encapsulating rhG-CSF were...

The objective of present work was to formulate and evaluate Fluconazole (FLZ) microsponges using quasi emulsion solvent diffusion technique and microsponge gel by using carbopol. Microsponges containing FLZ were obtained successfully with different proportions of ethyl cellulose polymer (EC). The formulations were studied for particle size and physical characterization. The physical characteriz...

The aim of this study was to prepare Spherical agglomerates of Carbamazepine by Quesi-Emulsion Solvent Diffusion system (QESDS) with Ethanol-Chloroform-Water system. Granules were prepared by wet granulation method with different excipients.The prepared agglomerates were evaluated for flowability, compressibility, wettability, packability and solubility. Tablets were prepared and evaluated for ...

In the present study controlled release formulation of Indomethacin microsponges were prepared by using Eudragit RS 100, pH independent release retardant polymer and PVA, stabilizer or emulsifier. Microsponges were prepared by Quasi emulsion solvent diffusion method by changing drug polymer ratio (3:1, 4:1, 5:1) and process was optimized. Microsponges were evaluated by micromeritic properties, ...

Silk fibroin (SF) has been widely investigated in biomedical applications due to its biodegradability and biocompatibility. The objective of this work was to prepare SF spheres for drug delivery application. Drug-loaded SF spheres with and without polyethylene glycol diglycidyl ether (PEGDE) crosslinking were prepared by a water-in-oil emulsion solvent diffusion method. Blue dextran was used as...

ber af problems fer nnr instantaneously While solvent-assisted emulsion systems have met with a degree of success in formulating pressure sensitive adhesives, they have several disadvantages. The solvent content of these systems precludes totally solvent-free adhesives. Also. there is reported evidence that surfactants used to stabilize the emulsion can adversely affect tack properties of the f...

Tuberculosis is an infectious disease caused by Mycobacterium Tuberculosis which attacks lungs and other parts of the body. Isoniazid is a hydrophilic drug that is having a first line antituberculosis drug. Entrapment Efficiency has been improved by preparing Solid Lipid Nanoparticles (SLNs). Two different variable Stearic acid and Tween 80 were used by using w/o/w double emulsion-solvent evapo...

Information on the preparation and properties of starch/gelatin blend microparticles with and without crosslinking for drug delivery is presented. The blend microparticles were prepared by the water-in-oil emulsion solvent diffusion method. Glutaraldehyde and methylene blue were used as the crosslinker and the water-soluble drug model, respectively. The blend microparticles were characterized b...

Microsponge containing ketotifen drug with three different proportions of ethyl cellulose and drug were obtained successfully using quasi-emulsion solvent diffusion method. These formulations were studied for particle size and physical characterization. These microsponges enriched gel formulation were prepared by using 2 and 3 % w/w of SCMC and studied for viscosity, pH, gel strength, spreadabi...

The aim of this study was to investigate non-solvent precipitation of starch to produce nanoparticles that could be used in Pickering emulsions. The material used was waxy maize, modified with octenyl succinic anhydride. Different methods of non-solvent precipitation were investigated, and a method based on direct mixing of an 8% starch solution and ethanol (ratio 1:1) was found to produce the ...
