Preparation and characterization of PLGA microspheres by the electrospraying method for delivering simvastatin for bone regeneration.

Microparticles formulated from poly (D,L-lactic-co-glycolide) (PLGA), a biodegradable polymer, have been investigated extensively as a drug delivery system. In this study, solid tiny PLGA microspheres were fabricated using the electrospraying method. PLGA polymer was dissolved in dichloromethane (DCM), and the solution was electrosprayed.
