Summary

Introduction

The goal of this study was to develop a novel drug delivery system (NDDS) of lamivudine (LAM) to overcome some drawbacks associated with LAM short half-life. To fulfill this goal, polymeric LAM-loaded nanoparticles were prepared and their transdermal deliveries via passive and microneedles (MNs)-mediated transport were investigated. A novel approach involving LAM-loaded nanoparticles and MNs insertion was used as a NDDS to enhance transdermal delivery of small molecular weight drugs across the skin layers [6]
