Favipiravir (T-705) is a potent and selective antiviral agent that functions as a viral RNA-dependent RNA polymerase inhibitor. Following intracellular conversion to its active ribofuranosyl triphosphate metabolite, it selectively blocks viral RNA synthesis without inhibiting host cellular RNA or DNA synthesis. This mechanism leads to the suppression of viral replication and effective inhibition of influenza virus proliferation. [1][2]

Q: Why does a DMSO stock precipitate in media/saline?
A: It is caused by unheated aqueous media (supersaturation), local solvent shock, or incorrect mixing sequence.
How to fix it?
- Preheat media/saline to 37°C.
- Mix rapidly (pipette/vortex) upon addition.
- For complex mixes, always add the aqueous phase last.
- Re-dissolve minor precipitates with a 37°C water bath and sonication (≤30 min).
Pre-aliquoted for Longevity: Solid-state aliquots offer significantly longer shelf life compared to stock solutions, ensuring maximum stability for every use.
