A study was performed to show whether debrisoquine phenotyping could be performed as an overnight procedure. Phenotyping of 33 normal volunteers was carried out during the day and night. A good correlation was observed between the day- and night-time metabolic ratios, although wide variation was observed in 3 subjects.
