Nasal Spray

Ena Respiratory's nasal spray reduces COVID-19 replication by 96%

Australian biotech Ena Respiratory has revealed that its self-administered nasal spray INNA-051, when taken once or twice weekly, reduced viral replication of SARS-CoV-2 by up to 96%, according to one animal study conducted by Public Health England (PHE), and a second study investigating the treatment in rhinovirus infection in human airway cells.

The therapy works by activating epithelial cells in the body’s airways to boost immune response at the primary site of infection, which was shown in studies to “dramatically” reduce infection and replication rates of COVID-19 in animals.<

Drug-free nasal spray could prevent COVID-19 infection, promising data show

Auris Medical has revealed promising new in vitro data for AM-301, its drug-free nasal spray, showing that the product could potentially protect from COVID-19.  

The data indicated that the spray may prevent SARS-CoV-2 infection in the nasal epithelial cells, which are the body’s first point of contact with inhaled allergens and pathogens. It protects these cells by forming a protective layer around them.
