Depending on the surface area and depth of the wound,<unk> blood serum concentrations of no more than 40 µg/ml are expected, with peak concentrations reached after 2 to 4 hours. The terminal half-life varied between 8.5 and 19.9 hours in studies. These data have been obtained from 15 patients with comparatively shallow wounds.
