Nitric oxide

Context: Effectiveness of Nitric oxide nasal spray for viral treatment is under consideration.

What is Nitric oxide nasal spray therapy?

• Nitric oxide is known to have a broad antimicrobial effect against bacteria, fungi, helminths, protozoa and viruses.
• To assess the potential of NO as a treatment for SARS-CoV-2 infection, researchers evaluated its vitro antiviral effect on SARS-CoV-2 replication and published their findings

And what is this spray?

• It has been developed by a Vancouver-based biotech firm, SaNOtize Research and Development Corporations, along with St Peter’s hospitals, NHS Foundation Trust in Surrey, and Berkshire and Surrey Pathology Services.
• The spray releases a small, topical amount of nitric oxide that is well known to kill viruses including SARS-CoV-2. It is non-specific and thus kills any virus.
