Ved terapeutiske doser kunne der kun måles sporadiske og yderst lave koncentrationer af intakt orlistat i plasma (< 10 ng/ ml eller 0, 02 mikromol) uden tegn på akkumulering, hvilket er i overensstemmelse med en minimal absorption.
In general, at therapeutic doses, detection of intact orlistat in plasma was sporadic and concentrations were extremely low (< 10 ng/ ml or 0.02 µmol), with no evidence of accumulation, which is consistent with minimal absorption.
