What is amantadine and rimantadine?
Amantadine and rimantadine are cyclic amines used in the treatment of influenza virus infection. The mechanism of action of these drugs involves inhibiting the uncoating of viral RNA in infected cells and thus effectively preventing viral replication.
Is zanamivir a Tamiflu?
Relenza (zanamivir) and Tamiflu (oscltamivir phosphate) are antiviral medications used to treat flu symptoms caused by influenza virus in patients who have had symptoms for less than 2 days.
Which disease can be treated with oseltamivir and zanamivir?

What is the difference between oseltamivir and zanamivir?
Zanamivir is indicated for use against influenza A/H1N1 virus strains that are resistant to oseltamivir. In conclusion, compared with zanamivir, oseltamivir was shown to be less effective against influenza B but more effective against influenza A/H3N2.
Who should not take Tamiflu?

What is the difference between amantadine and oseltamivir?
Amantadine and rimantadine are M2 proton channel blockers that inhibit virus uncoating; oseltamivir and zanamivir are neuraminidase (NA) inhibitors that inhibit virus release. However, recent years have witnessed a drastic increase in instances of drug resistance, and flu strains that are resistant to both classes of drugs have been reported.
What are amantadine and rimantanadine?
Amantadine and rimantadine are antiviral drugs in a class of medications known as adamantanes. These medications are active against influenza A viruses, but not influenza B viruses.
What is the prevalence of oseltamivir resistance in influenza?
Development of resistance to oseltamivir during treatment was more common among seasonal influenza A (H1N1) virus infections (27%) compared with seasonal influenza A (H3N2) (3%) or B (0%) viruses in another study [123].
What is oseltamivir resistance to influenza A (H3N2) pdm09 viruses?
