in this study, microspheres containing estradiol valerate were prepared by solvent evaporation method using poly (glycolide-co-lactide) (plga 50:50) and poly (lactide). the effect of different process variables such as polymer type, drugpolymer ratio, stirring rate, volume of internal phase and temperature of external phase on the morphology, particle size distribution, encapsulation efficiency...

A common approach for building a drug delivery system is to incorporate the drug within the nanocarrier that results in increased solubility, metabolic stability, and improved circulation time. However, recent developments indicate that selection of polymer nanomaterials can implement more than only inert carrier functions by being biological response modifiers. One representative of such mater...

In last few decades, there has been a considerable research interest in the area of drug delivery using polymer based particulate delivery systems as carriers for small and large molecules. Particulate systems like nanoparticles and micelles have been used as a physical approach to alter and improve the pharmacodynamic and pharmacokinetic profiles of various types of drug molecules. Due to the ...

The application of natural polysaccharides in novel drug delivery systems to deliver the bioactive agents has been hampered by the synthetic polymers. The main benefits of the natural polysaccharides are their being biodegradable, biocompatible, non-toxic, richly available and less expensive. Because of the advances in drug delivery technology, natural polysaccharides are included in novel drug...
