Antiviral drugs are a class of medicines designed to prevent or control viral infections by targeting different stages of the viral life cycle. They work by inhibiting viral entry, replication, protein synthesis, or the release of newly formed viruses from infected cells. These medicines are used to manage infections such as influenza, HIV, hepatitis, herpes, and COVID-19. Some antiviral agents help reduce the severity and duration of infections, while others suppress viral activity over the long term. Treatment selection depends on the type of virus, disease severity, patient health, and antiviral resistance patterns.
