Brief Summary:
This single-arm, open-label, non-randomized study will evaluate the effect of danoprevir/ritonavir on the pharmacokinetics of escitalopram and S-demethylcitalopram in healthy volunteers. Healthy volunteers will receive oral doses of danoprevir/ritonavir and escitalopram. The anticipated time of the study is 6 weeks.

Arm Intervention/treatment
Experimental: Single arm Drug: danoprevir
oral doses of danoprevir

Drug: escitalopram
oral doses of escitalopram

Drug: ritonavir
oral doses of ritonavir

Primary Outcome Measures :
  1. Change in area under the plasma concentration time curve (AUC) of escitalopram [ Time Frame: Approximately 4 weeks ]

Secondary Outcome Measures :
  1. Safety: Incidence of adverse events [ Time Frame: Approximately 6 weeks ]
  2. Effect on pharmacokinetics of major escitalopram metabolite: change in AUC of S-demethylcitalopram [ Time Frame: Approximately 4 weeks ]
  3. Effect of co-administration of escitalopram on danoprevir/ritonavir steady-state pharmacokinetics: change in AUC of danoprevir/ritonavir [ Time Frame: Approximately 4 weeks ]
