The sofosbuvir (SOF) plus ledipasvir (LDV) fixed dose combination is the first direct action antiviral (DAA) single-treatment regimen (STR) to be commercialized. It is approved for the treatment of Hepatitis C virus (HCV) genotypes 1,3,4,5 and 6. Following approval in 2014, new pharmacokinetics and pharmacodynamics data were reported, which led to important clinical applications. Areas covered: This article reviews the pharmacokinetic and pharmacodynamic properties of the SOF/LDV fixed dose combination for the treatment of HCV. The topics covered include data regarding the drug´s absorption, distribution, metabolism and excretion and antiviral activity strategies such as the clinical dose selection and treatment duration. Expert opinion: The SOF/LDV fixed dose combination has good pharmacological properties that lead to a high sustained virological response after 12 or 24 weeks of treatment; there is minimal interference with other drugs or associated renal or hepatic impairment, such that dose adjustment is not necessary.
