SD | 0.32 | 0.07 | 0.53 | 764 | 2.16 | 26.2 | 55.8 | 0.3 |
30 mg mean | 0.25 | .005 | 2.09 | 4231 | 2.83 | 222.3* | 310.73 | 1.3 |

The difference in half-life between 10 and 30 mg is a result of the limitation of the assay for the LCMS method with the levels at the lower dose being closer to the lower limit of quantitation.
