Final answer:
Sofosbuvir and ledipasvir represent an antiviral combination for hepatitis C, which helps to suppress the replication of the virus and improve liver function.
Step-by-step explanation:
Sofosbuvir and ledipasvir represent an antiviral combination for hepatitis C. Hepatitis C, a viral infection that affects the liver, can be treated with a combination of these medications. Sofosbuvir is a nucleotide polymerase inhibitor that prevents the synthesis of the hepatitis C virus, while ledipasvir acts as a direct-acting antiviral against the virus. Together, these drugs help to suppress the replication of the virus and improve liver function in patients with hepatitis C.The use of combination therapies is crucial in the treatment of viral infections like hepatitis C to reduce the likelihood of the virus developing resistance to the medication.
