New Nasal Spray Shows Promise in Blocking Multiple Respiratory Viruses

Developed by Brigham and Women’s Hospital, the drug-free PCANS spray could protect against COVID-19, flu, and other infections.

PCANS (Pathogen Capture and Neutralizing Spray) is a nasal spray designed to trap and neutralize respiratory pathogens.
The spray forms a gel-like matrix in the nasal cavity, capturing and neutralizing viruses and bacteria without affecting breathing.
In lab tests and mouse studies, PCANS showed over 99.99% effectiveness in blocking viruses like influenza and SARS-CoV-2.
The spray uses FDA-approved inactive ingredients and has demonstrated prolonged nasal cavity retention of up to eight hours.
Human clinical trials are the next step to confirm the safety and efficacy of PCANS for broad-spectrum respiratory infection prevention.
