Table 2
Distribution of estimated peak concentrations (
) for isoniazid and rifampin.
| Drug | Diabetics (early TDM) | Nondiabetic slow responders (standard TDM) | value |
| Rifampin (expected range 8–24 g/mL) | | | | Mean g/mL ± SD | | | | Below expected range (%N) | 12 (60) | 4 (41) | |
| Isoniazid (daily) (expected range 3–6 g/mL) | | | | Mean g/mL ± SD | | | | Below expected range (%N) | 11 (65) | 5 (63) | |
| Isoniazid (intermittent) (expected range 9–18 g/mL) | | | | Mean g/mL ± SD | | | | Below expected range (%N) | 3 (75) | 1 (17) | |
