Genemsnitlige maksimum og minimum plasmakoncentrationer ved steady state hos patienter var 2, 9±1, 6 mg/ l (interval 0, 02- 7, 6 mg/ ml) og 0, 2±0, 2 mg/ l (interval 0, 010- 1, 29 mg/ l) under et terapeutisk 800 mg daglig dosis regime.
Mean peak and trough plasma concentrations at steady state in patients were 2.9±1.6 mg/ l (range 0.02- 7.6 mg/ l) and 0.2±0.2 mg/ l (range 0.010 to 1.29 mg/ l), during a therapeutic 800 mg once-daily dose regimen.
