Telaprevir is an oral antiviral drug that acts as a protease inhibitor, specifically inhibiting the NS3/4A protease of hepatitis C virus (HCV). It was used in combination with other agents for the treatment of chronic hepatitis C infection, genotype 1. While it was previously approved, telaprevir has been withdrawn from the market in many countries due to adverse effects and the development of more effective agents.
Pharmacokinetics
Pharmacokinetic model in adult healthy subjects and patients with chronic hepatitis C. Oral administration under fed conditions.
