“Current nasal sprays offer limited protection against respiratory pathogens because they have a single mechanism of protection. They either neutralize pathogens or block their entry into the cells lining the nose, and they perform both tasks with limited efficacy.

‘We developed a drug-free formulation to block germs in three ways — the spray forms a gel-like matrix that enhances the capture of respiratory droplets, immobilizes the germs blocking their transport into the nasal lining, and effectively neutralizes them, preventing infection,’”

New, promising data on Profi Nasal Spray (aka PCANS) as prophylaxis for respiratory viruses:

“The researchers developed the formulation and studied its ability to capture respiratory droplets in a 3D-printed replica of a human nose. They showed that when sprayed in the nasal cavity replica, PCANS captured twice as many droplets as mucus alone.
