Author information

Department of Pharmacy, St. Michael's Hospital, Toronto, Ontario, Canada.


The detailed pharmacokinetics of fluconazole in serum and cerebrospinal fluid (CSF) were studied in a patient with acquired immunodeficiency syndrome and cryptococcal meningitis, after an intravenous dose of 400 mg. Fluconazole exhibited a serum elimination half-life of 34.2 hours, distribution volume of 0.56 L/kg, and clearance of 0.19 ml/min/kg. Peak CSF concentration occurred at 4 hours after the dose. Overall penetration of fluconazole based on the ratio of areas under the curve of CSF to serum was 70%. The drug exhibited an excellent pharmacokinetic profile for treatment of central nervous system fungal infections.
