Used in the treatment of chronic hepatitis C virus (HCV) infection, this compound acts as a nucleotide analog inhibitor that interferes with the viral RNA replication process. It is effective against multiple genotypes of HCV and is typically administered in combination with other antiviral agents. The drug enables high cure rates with shorter treatment durations and fewer side effects compared to older therapies. It plays a key role in oral direct-acting antiviral regimens, making HCV treatment more accessible and improving patient outcomes globally.
