Emerg Infect Dis. 2019 Oct;25(10):1969-1972. doi: 10.3201/eid2510.190607. Epub 2019 Oct 17.

Abstract

Baloxavir showed broad-spectrum in vitro replication inhibition of 4 types of influenza viruses (90% effective concentration range 1.2-98.3 nmol/L); susceptibility pattern was influenza A ˃ B ˃ C ˃ D. This drug also inhibited influenza A viruses of avian and swine origin, including viruses that have pandemic potential and those resistant to neuraminidase inhibitors.
