Abstract
One hour after intravenous doses of 50 mg/d fluconazole for 6 days or 100 mg/d for seven days to healthy subjects, the cerebrospinal fluid concentrations of fluconazole were 1.26 mg/L and 2.74 mg/L, respectively. These values were approximately 52% and 62% those of serum. Four patients with an initial clinical diagnosis of meningitis also had significant concentrations of fluconazole in the cerebrospinal fluid.
