failed to reach significanceP = 0.0524
Values for bufuralol could not be calculated, but for the other four drugs, 2.7- to 4.8-fold increases in area under the curve (AUC) were observed, together with 60–70% decreases in drug clearance (Table 1 ). Of the changes in clearance, those for tolbutamide (adjusted P = 0.0198) and buproprion (adjusted P = 0.00096) were statistically significant, and that for midazolam marginally failed to reach significance (adjusted P = 0.0524).
