[Treatment of chronic hepatitis C virus infection at the beginning of a new era].

After 2010 the therapy of chronic HCV infection entered a completely new era -  the era that is marked with the gradual introduction of the so-called directly acting antivirals into treatment schemes of this serious disease. The term directly acting antivirals (DAA) covers low-molecular substances that inhibit viral nonstructural proteins -  enzymes involved in the HCV replication cycle. At present, the first 2 representatives of DAA, Boceprevir and Telaprevir, have been approved for chronic HCV infection indication. The synoptic article pays the greatest attention to these 2 representatives, along with mentioning some other substances that are under later phases of clinical development and are likely to be approved in the near future.
