Sulphobutylether beta cyclodextrin sodium (SBECD) levels in patients on intermittent dialysis receiving intravenous voriconazole. Patients no. 2–4 with acute renal failure without recovery of renal function under intermittent dialysis receiving intravenous voriconazole show higher levels of sulphobutylether beta cyclodextrin sodium (SBECD) as compared to patient no. 1 with recovery of renal function. For comparison, in healthy volunteers peak SBECD levels of 130 μg/ml (dotted line) were measured immediately following administration of 1600 mg SBECD as a single infusion .
