Nanomedicine “New Food for an Old Mouth”: Novel Approaches for the Treatment of COVID-19

Abstract

Coronavirus disease (COVID-19) is an infectious disease caused by coronavirus. Developing specific drugs for inhibiting replication and viral entry is crucial. Several clinical trial studies are underway to evaluate the efficacy of anti-viral drugs for COVID-19 patients. Nanomedicine formulations can present a novel strategy for targeting the virus life cycle. Nano-drug delivery systems can modify the pharmacodynamics and pharmacokinetics properties of anti-viral drugs and reduce their adverse effects. Moreover, nanocarriers can directly exhibit anti-viral effects. A number of nanocarriers have been studied for this purpose, including liposomes, dendrimers, exosomes and decoy nanoparticles (NPs). Among them, decoy NPs have been considered more as nanodecoys can efficiently protect host cells from the infection of SARS-CoV-2. The aim of this review article is to highlight the probable nanomedicine therapeutic strategies to develop anti-viral drug delivery systems for the treatment of COVID-19.
