Current and Future Medications for Hepatitis C (cont.)
IN THIS ARTICLE
What medications treat or cure hepatitis C (DAAs, interferons, ribavirin)?
Hepatitis C treatments once involved months of injected interferons with up to 50% cure rates, and serious side effects. With newer medications hepatitis C can be treated with oral combinations of medicines for several weeks. These are generally well-tolerated and yield sustained cure of virus from the blood in over 90% of cases.
The goal of treating HCV-infected persons is to reduce the risk of death, end-stage liver disease, and other liver-related adverse events by achievement of virologic cure which is determined by sustained virologic response (SVR). Sustained virology response means complete disappearance of the HCV for at least 12 weeks after stopping treatment.
DAAs (Direct-Acting Agents, Protease Inhibitors, Nucleotide Polymerase Inhibitors, and NS5A Inhibitors)
These drugs are called direct-acting agents (DAA) because unlike interferons and ribavirin, they directly block growth of the hepatitis C virus. They are most often used in combinations.
Examples of HCV treatment combinations containing protease inhibitors and nucleotide polymerase inhibitors:
How do protease inhibitors work?
Protease Inhibitors are termed direct-acting antiviral agents (DAA). They directly act on the virus by inhibiting certain enzymes and proteins necessary for replication of the HCV virus.
How do nucleotide polymerase inhibitors work?
Nucleotide analog polymerase inhibitors are another type of direct-acting antiviral agents (DAA). They block the action of proteins that HCV uses for making new viruses.
How do NS5A inhibitors work?
These are direct-acting antivirals that block the action the HCV NS5A protein and interfere with making new viruses.
Who should not use these medications?
The contraindications, warnings, and precautions for ribavirin apply when ribavirin is combined with these agents.
