The AUC 0168h,sema,SS and other steady-state pharmacokinetic endpoints ( C max,sema,SS and R acc,DC,sema ) were analyzed separately by linear normal models based on log-transformed values with race (Japanese or Caucasian), dose group (0.5 mg or 1.0 mg), and race-by-dose group interaction as fixed factors

The titration schedule is similar but tops out one step earlier

This could help extend its half-life
