In vitro evaluation of nebulized eucalyptol nano-emulsion formulation as a potential COVID-19 treatment.

ABSTRACT: Coronavirus is a type of acute atypical respiratory disease representing the leading cause of death worldwide. Eucalyptol (EUC) known also as 1,8-cineole is a potential inhibitor candidate for COVID-19 (main protease-M^pro) with effective antiviral properties but undergoes physico-chemical instability and poor water solubility. Nano-emulsion (NE) is a promising drug delivery system to improve the stability and efficacy of drugs. This work focuses on studying the anti- COVID-19 activity of EUC by developing nebulized eucalyptol nano-emulsion (EUC-NE) as a potentially effective treatment for COVID-19. The EUC -NE formulation was prepared using Tween 80 as a surfactant. In vitro evaluation of the EUC-NE formulation displayed an entrapment efficiency of 77.49 %, a droplet size
