Drug Concentration parameters: The peak concentration (μg/g, A) and peak duration (seconds, B) was comparable between the Cerebral Hypoperfusion (CHP, n=8) and the normal perfusion (NP, n=5) groups but the area under the concentration time curve (μg/g*min) was showed a trend towards an increase with CHP (C). The final concentrations (μg/g, D) at the end of twenty minutes were similar in the NP and CHP groups. In animals with breeched BBB, there seems to be no sustained benefit of injecting mitoxantrone during CHP.
