Abstract: Trough concentrations achieved after 600 mg once daily dosing (median: 2017 ng/mL, 95% CI:445-9830) and after reduced dose (400 mg) efavirenz (median: 1349ng/mL, 95% CI: 297-6553) provided complete protection against wild-type virus and the
Y181C mutant, and median trough concentrations provided about 90% protection against the
K103N and
G190S mutants.
Abstract: We predicted that plasma concentrations of 11, 36, 1287 and 1486ng/mL prevent 90% sexual transmissions with wild type and
Y181C,
K103N and
G190S mutants, respectively.
