Reduction in the COVID-19 pneumonia case fatality rate by silver nanoparticles: A randomized case study.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has devastated mankind. To date, no approved treatment is available to completely combat this disease. Although many studies reported the potential of silver nanoparticles' (AgNPs) action mechanism and effect against SARS-CoV-2, this is the first clinical trial that aimed to prove this effect. This open-label, randomized, parallel-group, investigator-initiated study (IIS) was conducted in India from 2021 to 2022 and included 40 patients diagnosed with moderately-severe to severe COVID-19 pneumonia. This study proved a significantly higher survival rates (p < 0.05) and significantly lower number of days until supplemental oxygenation was required (p < 0.0001) for patients receiving intravenous AgNPs in form of AgSept® in addition to the standard COVID-19 treatment. This study highlights the importance of intravenous AgNPs administration in the treatment of virus-induced pneumonia.
