Preclinical studies suggest a drug-free nasal spray could ward off respiratory infections

A new study details how a nasal spray formulated by investigators from Brigham and Women’s Hospital, a founding member of the Mass General Brigham healthcare system, may work to protect against viral and bacterial respiratory infections

The spray is called “Pathogen Capture and Neutralizing Spray” (PCANS) for now

This data suggest PCANS as a promising daily-use prophylactic against respiratory infections.

The study is paywalled, and the abstract doesn’t list its ingredients beyond

The formulation consists of excipients identified from the FDA’s Inactive Ingredient Database and Generally Recognized as Safe list to maximize efficacy for each step in the multi-modal approach.

Based on that description, its ingredients might not be very different from Covixyl, though it claims to be much more effective.

Edit: Apparently its already for sale, I included some details in a comment
