Which of the following antiviral drug is used to treat influenza A?
Table 1. Antiviral Medications Recommended for Treatment and Chemoprophylaxis of Influenza
| Antiviral Agent | Activity Against | Use |
|---|---|---|
| Oral Oseltamivir | Influenza A and B | Chemo- prophylaxis |
| Inhaled Zanamivir | Influenza A and B | Treatment |
| Chemo- prophylaxis | ||
| Intravenous Peramivir | Influenza A and B4 | Treatment |
What viruses can be treated with antivirals?
Healthcare providers prescribe antivirals to treat chronic or life-threatening viral infections, including:
- Coronaviruses like COVID-19.
- Ebola.
- Flu, including H1N1 (swine flu).
- Genital herpes.
- Hepatitis B and hepatitis C.
- Human immunodeficiency virus (HIV).
What treatments are available for influenza?
There are four FDA-approved influenza antiviral drugs recommended by CDC for use against recently circulating influenza viruses.
- Rapivab (peramivir)
- Relenza (zanamivir)
- Tamiflu (oseltamivir phosphate, also available as generic)
- Xofluza (baloxavir marboxil)
What is the standard treatment for COVID-19?
The U.S. Food and Drug Administration (FDA) has approved remdesivir (Veklury) for the treatment of COVID-19 in certain situations. Clinical management of COVID-19 includes infection prevention and control measures and supportive care, including supplemental oxygen and mechanical ventilatory support when indicated.
Is azithromycin an antiviral?
The mechanisms of the antiviral effect of AZM support a large-spectrum antiviral activity. Azithromycin appears to decrease the virus entry into cells [2, 8]. In addition, it can enhance the immune response against viruses by several actions.
How does Remdesivir work on coronavirus?
Remdesivir works by interrupting production of the virus. Coronaviruses have genomes made up ribonucleic acid (RNA). Remdesivir interferes with one of the key enzymes the virus needs to replicate RNA. This prevents the virus from multiplying.
Which following agent is the preferred antiviral agent in the treatment of human influenza?
The most useful anti-influenza medications for treating infection with influenza are neuraminidase inhibitors – oseltamivir (trade name: Tamiflu®) and zanamivir (trade name: Relenza®).
How is Tamiflu effective against viruses?
Tamiflu binds to the neuraminidase on the surface of the virus particles and hence inhibits the new viral particles’ chemical ability to escape from the infected cell. Hence the influenza virus is restricted to a smaller number of cells and the body’s immune system has a better chance of killing the virus.
