In healthy volunteers, the CYP3A4 inhibitor ketoconazole increased the Cmax and AUC concentrations of<unk>  by 3- to 10-fold. This was accompanied by a QT interval prolongation of about 10–20 milliseconds when<unk>  10 mg four times daily and ketoconazole 200 mg twice daily were administered, whereas<unk>  by itself at the dosage assessed produced no such effect. As such,<unk>  with ketoconazole or other CYP3A4 inhibitors is a potentially dangerous combination.
