Abstract:
INTRODUCTION:Telaprevir is one of the first direct-acting antiviral drugs approved for the treatment of the hepatitis C virus (HCV) genotype 1. Following its approval in 2011, new data regarding the pharmacokinetics and pharmacodynamics were reported, leading to important clinical applications. AREAS COVERED:This article reviews the pharmacokinetic and pharmacodynamic properties of telaprevir for the treatment of the HCV. The areas covered include data regarding the drug's absorption, distribution, metabolism and excretion, in addition to the antiviral activity strategy such as the clinical dose selection and treatment duration. EXPERT OPINION:Telaprevir presents several pharmacological properties that could limit its administration such a high-fat, high-calorie meal; the need to be administrated with pegylated IFN plus ribavirin; and the drug-drug interaction profile. As a consequence and considering the new therapeutic arsenal against the HCV, the use of telaprevir as part of HCV therapy will be limited.
