Uses Favipiravir inhibits the RNA-dependent RNA polymerase (RdRp) — an enzyme that allows the coronavirus to replicate inside host cells.Inside the cells, favipiravir is converted to favipiravir ribofuranosyl-5′-triphosphate (favipiravir-RTP) by host cells. This molecule then blocks the RdRp enzyme of SARS-CoV-2, the virus that causes Covid-19.According to a statement, favipiravir works only during the earlier stages of the disease, when the viral replication is higher, but the body's immune response has not gone into overdrive.
Metabolism of favipiravir to its triphosphate form occurs in an extracellular environment in a concentration-dependent manner. The vRNA polymerase mistakenly recognizes favipiravir-RTP as a purine nucleotide. This favipiravir-RTP is misincorporated in nascent vRNA, or it may act by binding to conserved polymerase domains, preventing incorporation of nucleotides for vRNA replication and transcription.
