The Nitric Oxide Nasal Spray (NONS) was made by Glenmark Pharmaceuticals and SaNOtize Research & Development in Canada. It is used to treat viruses in adults in India. The virus that causes C-19 in the upper airways is what Fabispray nasal spray is meant to kill. According to what the company says, the Nitric Oxide Nasal is sprayed over the nasal mucosa, which works as a physical and chemical barrier against the virus. It says that it will stop the virus from taking hold and spreading to the lungs. https://www.themedicinekart.com/product-page/fabispray-nitric-oxide-nasal-spray-nons #fabispray #fabispraynasalspray
