Physical description & handling notes

slightly soluble in water
Favipiravir functions as a prodrug and undergoes ribosylation and phosphorylation intracellularly to become the active favipiravir-RTP. Favipiravir-RTP binds to and inhibits RNA dependent RNA polymerase (RdRp), which ultimately prevents viral transcription and replication.

GHS Hazard Classification

Reported hazard statements	H302 (40%), H315 (60%), H319 (60%), H335 (60%), H341 (20%), H361 (40%)

H302 (40%): Harmful if swallowed [Warning Acute toxicity, oral]

H315 (60%): Causes skin irritation [Warning Skin corrosion/irritation]

Documented Uses

In 2014, favipiravir was approved in Japan to treat cases of influenza that were unresponsive to conventional treatment. Given its efficacy at targetting several strains of influenza, it has been investigated in other countries to treat novel viruses including Ebola and most recently, COVID-19.
Breast Feeding; Lactation; Milk, Human; Antiviral Agents
Agents used in the prophylaxis or therapy of VIRUS DISEASES. Some of the ways they may act include preventing viral replication by inhibiting viral DNA polymerase; binding to specific cell-surface receptors and inhibiting viral penetration or uncoating; inhibiting viral protein synthesis; or blocking late stages of virus assembly.
J - Antiinfectives for systemic use
J05 - Antivirals for systemic use
