Table 1.
Pharmacokinetic parameters of methylprednisolone after a single 48 mg oral dose before and after repeated administration of itraconazole for 4 days to 14 subjects.
| Cmax (ng ml−1) | tmax (h) | t1/2 (h) | AUC(0,24 h) (ng ml−1 h) | |
|---|---|---|---|---|
| Methylprednisolone | 453 [401,505] | 2 (1–4) | 3.2 [2.5–3.9] | 2773 [2223,3323] |
| Methylprednisolone+itraconazole | 713 [637,788] | 3 (1–5) | 5.5 [5.2,5.9] | 7011 [6275,7747] |
| Differences between means | 260* [177,343] | – | 2.25* [1.5,3] | 4238* [3421,5055] |
Data are mean [95% CI]; tmax is given as median (range). Cmax peak plasma concentration, tmax time to Cmax, t1/2 elimination half-life, AUC area under the plasma concentration-time curve.
paired t-test : P < 0.001.
