The class of drug used in conjunction with interferon for the treatment of Hepatitis C is protease inhibitors. These drugs work by directly inhibiting the viral protease enzyme, which is essential for the maturation of the Hepatitis C virus. By blocking this enzyme, protease inhibitors prevent the virus from replicating effectively, thereby enhancing the antiviral effects of interferon. This combination therapy has significantly improved treatment outcomes for patients with Hepatitis C, leading to higher cure rates compared to using interferon alone.

Other options, such as nucleotide analogs, immunosuppressors, and interleukin-2, do not have the same role or effectiveness in conjunction with interferon specifically for Hepatitis C treatment. Nucleotide analogs are typically used in the treatment of other viral infections. The other two categories are not relevant to directly targeting Hepatitis C virus replication in the same manner as protease inhibitors when combined with interferon.
