Enzymatica AB (publ) announced new study: ColdZyme breaks the infection cycle, limiting the spread of viruses to more cells. The researchers believe that ColdZyme would have the same effect on other respiratory viruses. ColdZyme mouth spray is sold in more than 30 markets on four continents, also under brand names such as ViruProtect, Bisolviral and ADerogyl.

Previous studies have shown how application of ColdZyme before infection blocks viruses from sticking to human cells. The new study shows that ColdZyme also reduces viral load and the virus's ability to spread in cell cultures that were already infected with virus (influenza A, H3N2). The research from the Medical University of Innsbruck shows a more than 99% lower viral load after only three treatments with ColdZyme, compared to infected cells that were treated with salt solution.
