NS5A inhibitor

An NS5A inhibitor is a type of medication used to treat hepatitis C virus (HCV) infection. It works by blocking a specific protein (called NS5A) that the virus needs to replicate and spread in the body. By inhibiting this protein, the drug prevents the virus from multiplying, helping the immune system clear the infection. NS5A inhibitors are often part of combination therapies and have contributed to higher cure rates and shorter treatment durations for hepatitis C. They are generally well-tolerated and represent a significant advance in managing this viral infection.
