Naproxen Application:
Arbidol is an antiviral treatment for influenza infection used in Russia and China. The drug is manufactured by Pharmstandard and since 2005 it has been the number one best-selling over-the-counter drug in Russia. Although some Russian studies have shown it to be effective, it is not approved for use in Western countries. Chemically, arbidol features an indole core, functionalized at all but one positions with different substituents. The drug inhibits viral entry into target cells and also stimulates the immune response.
