Abstract:
:We analyzed the relationship between itraconazole (ITZ) and hydroxy-itraconazole (OH-ITZ) levels in 1223 human samples. Overall, there was a statistically significant correlation between ITZ and OH-ITZ levels (correlation coefficient 0.7838), and OH-ITZ levels were generally higher than that of ITZ (median OH-ITZ:ITZ ratio 1.73; range 0.13 to 8.96). However, marked variability was observed throughout the range of ITZ concentrations. Thus, it is difficult to predict OH-ITZ concentrations based solely on ITZ levels.
