Some antiviral medications can boost the immune system to help fight off a viral infection, while others primarily work by stopping the virus from replicating [1.2.1, 1.3.2]. The question, 'Do antivirals affect the immune system?' reveals a complex and dynamic interaction, not a simple 'yes' or 'no' answer.

Originally developed as an antiviral in the 1960s, amantadine's dual nature was discovered serendipitously when it was found to also have antiparkinsonian effects. As a result, when answering the question, 'Which class is amantadine?', it is important to recognize its multiple pharmacological classifications based on its different mechanisms of action. (Markdown OK).

According to the Centers for Disease Control and Prevention (CDC), modern antiretroviral therapy can suppress the HIV virus to undetectable levels. A key component in achieving this is understanding what class of drug is bictegravir emtricitabine, as this combination leverages two powerful mechanisms to fight HIV.

In February 2022, bebtelovimab received an Emergency Use Authorization (EUA) from the U.S. Food and Drug Administration (FDA) for its potent neutralizing activity against certain SARS-CoV-2 variants. This action was based on the specific way the medication works. But what is the mechanism of action of Bebtelovimab?

Currently, there is no definitive sterilizing cure for chronic hepatitis B (CHB), and while tenofovir is a highly effective treatment, it does not achieve complete viral eradication for most patients. Instead, it functions as a potent antiviral to manage the infection over the long term.

Approved by the FDA in 2003, Fuzeon was the first medication of its kind to target the fusion step of the HIV lifecycle. This powerful antiretroviral helps answer the question, **what does Fuzeon do?**, by explaining its unique action against the virus in treatment-experienced patients.

In many pathogenic viruses, such as Coronaviridae and Flaviviridae, large polyproteins are cleaved to produce the final functional molecules [1.6.7]. A key product of this process is the **mat peptide**, or mature peptide, which is the final, biologically active form of a peptide after all post-translational modifications are complete [1.3.4].
