[Question] Nitric Oxide Spray… a cure for COVID19??

According to https://​​www.biospace.com/​​article/​​releases/​​uk-clinical-trial-confirms-sanotize-s-breakthrough-treatment-for-covid-19/​​

Patients with a self-administered nasal spray application found to have reduced SARS-CoV-2 log viral load by more than 95% in infected participants within 24 hours of treatment, and by more than 99% in 72 hours.
