"This breakthrough therapy, which has been shown to significantly reduce hospitalizations and deaths and can be taken at home, will change the way we treat COVID-19, and hopefully help reduce some of the significant pressures facing our healthcare and hospital systems."
Dr. Patrizia Cavazzoni, director of the FDA's Center for Drug Evaluation and Research, said authorizing the pill is a "major step forward" in fighting the pandemic.
"This authorization provides a new tool to combat COVID-19 at a crucial time in the pandemic as new variants emerge and promises to make antiviral treatment more accessible to patients who are at high risk for progression to severe COVID-19," she said in a statement.
Bourla added that Pfizer's pill comes at a crucial time for COVID-19 treatments with the emergence of the Omicron variant.
