A comparative study on the clinical effects of oxazepam and diazepam: Relationship between plasma level and effect.
The clinical effects of oxazepam and diazepam as oral premedicants were tested in a double-blind study of 60 children and 50 adults. The gas chromatographically measured concentrations of the active unconjugated forms of oxazepam and diazepam in the plasma were correlated to their clinical effects, as assessed both subjectively and objectively (sleep, sedation, apprehension, excitement, dizziness, emetic effect, headache, increase or decrease in systolic blood pressure, increase in pulse rate, venepuncture). No significant difference in the effects of these two benzodiazepine derivatives were observed, nor was there any obvious relationship between the plasma concentration and clinical effect.
