ANALYSIS: Five COVID nasal sprays that could change how we treat COVID
Covixyl-V is another nasal spray under development. It aims to prevent COVID by blocking or modifying the cell surface to prevent the virus from infecting.
A lab-based study shows the gas changes expression of receptors on the skin that would normally allow the virus to attach. This results in less SARS-CoV-2 attachment and infection. A spray of these genetic fragments delivered into the nose reduced virus replication in the nose and prevented disease in small animals.A third strategy is to change the nose environment to make it less hospitable for the virus.
