The purpose of this study was to prepare and characterize microspheres loaded by cyclosporine A(CyA)-cyclodextrin (CD) complex. To achieve this goal, PLGA microspheres loaded by CyA CD complex were prepared by multiple emulsificationsolvent evaporation methods.Morphology, size, encapsulation efficiency and drug release from these microspheres were evaluated. Microscopic evaluation of mi...

The objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (MA) using two polymers with different characteristics as ethylcellulose (EC) and/or cellulose acetate phthalate (CAP). Microspheres were prepared by the modified emulsion solvent evaporation (MESE). The effect of drug-polymer interaction was studied for each of microspheres. Important param...

        The purpose of this study was to prepare and characterize nimodipine loaded microspheres using ethyl cellulose (EC) as a carrier polymer through an emulsion solvent evaporation method. These evaluations characterized the pattern of drug release from prepared microspheres. Nimodipin loaded microspheres were prepared using an emulsification solvent evaporation method. The effect of proces...

Microspheres formulated from poly (D,L-lactic-co-glycolide) (PLGA), a biodegradable polymer, have been extensively evaluated as a drug delivery system. In this study, the preparation, characterization and drug release properties of the PLGA microspheres were evaluated. Simvastatin (SIM)-loaded PLGA microspheres were prepared by oil-in-water emulsion/solvent evaporation method. The microspheres ...
