Information
Ketoconazole (R 41400) inhibitscyclosporine oxidaseandtestosterone 6 beta-hydroxylasewithIC50of 0.19 mM and 0.22 mM, respectively. Ketoconazole is anandrogenbiosynthesis inhibitor.
In vitro
Ketoconazole interacts with androgen receptors in a competitive fashion in intact human foreskin fibroblasts. Ketoconazole competes for [3H]dexamethasone binding to fibroblast glucocorticoid receptors with IC50 of 0.3 mM. Ketoconazole reduces cell proliferation and [3H]thymidine incorporation with IC50 of 2.5 mM in the serum independent HT29-S-B6 colon cell clone. Ketoconazole inhibits the incorporation of [3H]thymidine with IC50 of 2 μM and 13 μM in the Evsa-T cell line and MDA-MB-231 cell line, respectively. Ketoconazole induces a decrease of the number of cells in S phase and a corresponding increase of the percentage of cells in Go-G1 in HT29-S-B6 cells. Ketoconazole is susceptable to several Malassezia species with minimum inhibitory concentrations (MICs) of 0.03 µg/mL.
In vivo
Ketoconazole (25 mg/kg, i.p.) significantly decreases plasma corticosterone and reduces low dose cocaine self-administration without affecting food-reinforced responding in rats. Ketoconazole raises the AUC of orally administered digoxin from 63 mg x h/L to 411 mg x h/L in rats. Ketoconazole raises the AUC of intravenously administered digoxin from 93 mg × h/L to 486 mg × h/L in rats. Ketoconazole increases digoxin bioavailability from 0.68 to 0.84 in rats, while mean absorption time is reduced from 1.1 hours to 0.3 hour.
