Also known asFavicovir Film Tablet + Hydroxychloroquine sulfate
SponsorHealth Institutes of Turkey
Drug classAntiviral combination (nucleoside analog + immunomodulator)
TargetViral RNA-dependent RNA polymerase (favipiravir); toll-like receptors and endosomal pathways (hydroxychloroquine)
ModalitySmall molecule
Therapeutic areaInfectious Disease / Virology
PhasePhase 3

Mechanism of action

Favipiravir is a nucleoside analog that selectively inhibits viral RNA-dependent RNA polymerase, preventing viral genome replication. Hydroxychloroquine is an immunomodulator that increases endosomal pH, inhibits toll-like receptor signaling, and has direct antiviral activity. The combination aims to suppress both viral replication and excessive inflammatory responses.
