Fapilavir is a new broad-spectrum anti-RNA virus drug

Studies show that in addition to influenza viruses, the drug also shows good antiviral effects on a variety of RNA viruses, such as Ebola virus, yellow fever virus, sand virus, foot-and-mouth disease virus, bunia virus, rabies virus, etc. It's mainly used in anti-virus drug

The mechanism of its actions is thought to be related to the selective inhibition of viral RNA-dependent RNA polymerase. Favipiravir is a prodrug and is metabolized to its active form, favirpiravir-RTP, following digestion. Human hypoxanthine guanine phosphoribosyltransferase (HGPRT) is believed to play a key role in this activation process. Favipiravir does not inhibit RNA or DNA synthesis in mammalian cells and is not toxic to them.
