In this context, it is interesting to note that publications indicate that individuals vaccinated against SARS-CoV-2 have lower viral loads and are less contagious24,25. Reznikov et al. Google Scholar. Thus, a nitric oxide nasal spray was shown to reduce the viral load in adult patients with mild COVID-19 infection, and an accelerated SARS-CoV-2 clearance compared to placebo was demonstrated18. J. Infect. Virol. Interestingly, significantly greater decrease in viral load was shown on day 4 of treatment in patients with high viral burden (Ct<25) treated with 0.1% azelastine compared to placebo, indicating that azelastine treatment may be advantageous for this patient population, particularly at an early timepoint of infection. https://doi.org/10.1016/j.bbrc.2020.11.095 (2021). Patient disposition. It would be desirable to extend the investigation of azelastine nasal spray as potential antiviral treatment with in vitro culture experiments. Struct.
