Abstract
The rapid development of direct-acting antiviral agents (DAA) for hepatitis C virus (HCV) therapy dramatically altered the treatment landscape of this disease. The DAA regimen is associated with various advantages including high sustained virological response (SVR) with minimum side effects and low pill load and specific inhibition of viral replication, which lowers dependence on the host cell. This regimen has substantially replaced conventional (interferon) therapy with high cure rates (> 90%) in most HCV populations. This review provides insight into clinical studies of NS3/4A protease inhibitors, NS5B viral polymerase inhibitor (nucleotide and non-nucleotide), and NS5A inhibitors, alone and in combination.
