Introduction
Fluconazole is a widely used drug that inhibits the synthesis of fungal cell membranes [1,2]. Its elimination is predominantly via renal excretion with most of the dose recovered in urine as an unchanged and active drug. As a result, drug pharmacokinetics are altered in patients with renal failure and it is essential to establish guidelines on how to handle this drug in those patients. Furthermore, in dialysis patients, the removal of the drug in the dialysate has to be elucidated to determine whether fluconazole should be administered after the session or not. A review of the literature was thus performed and analysis of the retrieved data permitted to establish dosage adjustment guidelines for fluconazole in patients with renal failure.
Pharmacokinetics
The oral bioavaibility of fluconazole is >90%, which enables us to administer it with similar doses by i.v. and oral routes. Neither food nor gastric pH modifications
Toxicity
Patients with renal failure
Haemodialysis patients
Patients on peritoneal diaysis
Patients on continuous renal replacement therapy
