Abstract
The pharmacokinetics of the hypoxic radio-sensitizer nimorazole were studied in 19 individuals after single oral doses of between 0.5-3.5 g. HPLC measurements showed, after a rapid absorption, a linear relationship between peak plasma concentration and given dose. Mean elimination half life was 3.1 h. A tendency to a dose-dependent variation in the apparent volume of distribution, total body clearance and elimination half life suggest non-linear pharmacokinetics of nimorazole. Tumour concentrations measured in 5 patients gave tumour/plasma ratios between 0.8-1.3. No toxicity was observed. The results indicate that nimorazole may have potential as a clinically useful hypoxic radiosensitizer.
