Objectives: Ocular drug delivery is a difficult challenge especially with topical intillation which results in rapid drainage and non-productive drug absorption. For the improvement of the pre-corneal retention time and enhancing the corneal permeability, colloidal drug delivery systems play an important role in enhancement of the ocular bioavailability. In this study, dirithromycin incorporated Kollidon® SR-based polymeric nanoparticles, an antibacterial agent, were formulated for the efficient treatment of severe ocular bacterial infections. Materials and Methods: In this study, dirithromycin was incorporated into the Kollidon® SR-based nanoparticles by spray drying method. In vitro characteristic properties were evaluated in detail during the storage period of three months at three different conditions. Results: The results of in vitro analyses revealed that characteristic properties of the particles were remained unchanged during the storage period of three months. Conclusion: Kollidon® SR-based polymeric nanoparticles are good candidates for drug delivery systems in the treatment of severe ocular bacterial infections with dirithromycin.
