Nitric oxide effect on coronavirus

Date: 26 April 2021 Tags: Miscellaneous


A multinational study has provided results of a trial that says that nitric oxide nasal spray can be an effective treatment to viral disease.



Scientists have not been able to identify a specific drug to control Covid-19 that has caused widespread mortality. The new study tries to address the shortcomings.



  • Nitric oxide has been found effective against microbes such as fungi, helminths, bacteria, protozoa and viruses.

  • Scientists studied the vitro antiviral effect of Nitric oxide on SARS-CoV-2 so that it can be used for treatment against Covid-19.


The spray

  • The spray will release a small amount of Nitric oxide inside the nasal cavity and kill any type of virus including SARS-CoV-2. The drug is non-specific in nature.

  • The study showed average reduction of viral load by about 95% in the first 24 hours. This reduction increases to 99% in next 72 hours.

  • The treatment is a post-exposure method and kills virus in nasal airways by preventing their movement towards lungs.

  • There has been instance of people using the spray immediately after small symptoms appear and prevent the infection from enhancing.
