Furosemide as a functional marker of acute kidney injury in ICU patients: a new role for an old drug

Filippo Mariano, Alberto Mella, Marco Vincenti, Luigi Biancone

Journal of Nephrology > 2019 > 32 > 6 > 883-893

New pharmacokinetics insight suggests that the furosemide pharmacology occurring in ICU patients with AKI is similar, but not equal to that described in chronic stable renal patients. Even if the diuretic response to furosemide is expressed by a steep dose–response curve positively correlated with renal function, pharmacodynamic limitations occur when creatinine clearance is < 20 ml/min or urine...
