What is antivirals and their examples?

Antivirals are medications used to treat viral infections by inhibiting the replication of viruses in the body. Some examples of antiviral medications include:

1. Acyclovir (Zovirax) - used to treat herpes simplex virus infections, including genital herpes, cold sores, and shingles.
2. Oseltamivir (Tamiflu) - used to treat and prevent influenza (flu) infections.
3. Ribavirin (Rebetol) - used to treat hepatitis C and respiratory syncytial virus (RSV) infections.
4. Ganciclovir (Cytovene) - used to treat cytomegalovirus (CMV) infections in immunocompromised patients.
5. Sofosbuvir (Sovaldi) - used to treat hepatitis C infections.
6. Zanamivir (Relenza) - used to treat and prevent influenza (flu) infections.
7. Valganciclovir (Valcyte) - used to treat CMV infections in immunocompromised patients.

Antivirals are medications that are used to treat viral infections. They work by either preventing the virus from replicating or by stopping the virus from entering the host cells.

- Ribavirin (Copegus) - hepatitis C virus (HCV), respiratory syncytial virus (RSV)
- Interferon - HCV, hepatitis B virus (HBV)
- Oseltamivir (Tamiflu) - influenza
- Zanamivir (Relenza) - influenza
