Highlights:
- Identify ranitidine bismuth citrate(RBC), a commonly used drug for the treatment of Helicobacter pylori infection, as a potent anti-SARS-CoV-2 agent, both in vitro and in vivo.
- RBC suppressed SARS-CoV-2 replication, leading to decreased viral loads in both upper and lower respiratory tracts, and relieved virus-associated pneumonia in a golden Syrian hamster model.
- RBC exhibited low cytotoxicity and protected SARS-CoV-2-infected cells with a high selectivity index of 975.
