The combination includes diphenhydramine, an antihistamine used for allergy symptoms. When paired with lactoferrin, a protein found in cow and human milk, the compounds were found to hinder the SARS-CoV-2 virus during tests in monkey cells and human lung cells.
The findings by David A. Ostrov, Ph.D., an immunologist and associate professor in the UF College of Medicine’s department of pathology, immunology and laboratory medicine and his colleagues, are published in the journal Pathogens.
“We found out why certain drugs are active against the virus that causes COVID-19. Then, we found an antiviral combination that can be effective, economical, and has a long history of safety,” Ostrov said.
