Preparation and Evaluation of Eudragit® L100 Nanoparticles LoadedImpregnated with KT Tromethamine Loaded PVA -HEC Insertions forOphthalmic Drug Delivery

preparation and evaluation of electrospun indomethacin loaded eudragit® s100 and eudragit® rs100 nanofibers for colon-targeted drug delivery

Preparation of Methotrexate loaded PLGA nanoparticles coated with PVA and Poloxamer188

Objective(s): Nanoparticles offer an attractive platform for drug delivery through a wide variety of the body's physiological barriers. Furthermore, modification of nanoparticle surface with moeites such as Poloxamer188 can enhance their accumulation and localization at disease site. In this work, we investigated the physiochemical effect of a scavenger receptor (SR-BI) interac...

Eudragit® L100/N-trimethylchitosan chloride microspheres for oral insulin delivery.

Effective oral delivery of protein and peptide drugs remains an active topic in scientific research. In this study, matrix type microspheres were prepared with Eudragit® L100 containing N-trimethylchitosan chloride to improve the permeation of insulin across the intestinal epithelium via the paracellular pathway. Insulin loaded microspheres were initially formulated in accordance with a factori...

Preparation of CMC/HEC Crosslinked Hydrogels for Drug Delivery

A novel crosslinked hydrogel was prepared from sodium carboxymethyl cellulose (CMC) and hydroxyethyl cellulose (HEC) using ammonium persulfate as an initiator and methylenebisacrylamide as a crosslinker for drug delivery. The chemical structure of the copolymer was characterized by Fourier transform infrared spectroscopy and X-ray diffraction, and the morphology was observed under scanning elec...

Simultaneous diagnosis and drug delivery by silymarin-loaded magnetic nanoparticles

Objective(s): The aim of this work was to prepare and characterize magnetic nanoparticles (MNPs) as theranostic system to act simultaneously as drug carrier and MRI contrast agent. Chitosan-coated MNPs (CMNPs) were prepared and loaded with silymarin. Silymarin-loaded CMNPs were characterized with various techniques and their potential as MRI contrast agent was also evaluated. Materials and Meth...
