Abstract:Hydrophilic polymer matrix systems (HPMSs) are a highly relevant tool for drugs delivery whose bioavailability is impaired by low hydrosolubility. Besides this, when associated with nanoparticles these systems can provide better control over release profile of the active drug, maintaining the posology. Since polyvinylpyrrolidone (PVP) and zinc oxide (ZnO) are safe materials for use in the human body, we studied the effects of ZnO nanoparticle ratios on the characteristics of PVP matrix. For that purpose, nanoc… Show more
