Nanotechnology by manipulation of characteristics of materials such as polymers and fabrication of nanostructures is able to provide superior drug delivery systems for better management and treatment of diseases.The nanostrctures employed as drug delivery systems have multiple advantages which make them the superior to conventional delivery systems. This book provides the formulation of carvedilol nanoparticles using nanoprecipitation technique and it's phsicoo-chemical characterization and invivo biodistribution studies.
