[The use of diuretics in kidney disease].

BACKGROUND

Diuretics are an important part of the therapy for a number of medical conditions such as heart, liver and kidney failure and hypertension. This article presents updated knowledge on the use of diuretics in kidney disease.

METHOD: The article is based on a literature search in PubMed, information obtained from textbooks on neurophysiology and kidney disease and on the authors' clinical experience.

RESULTS

Kidney disease affects the pharmacokinetics and pharmacodynamics of diuretics, and this must be taken into account when selecting a drug and determining the dosage. This applies particularly to nephrotic syndrome and severe chronic renal disease (GFR < 30 ml/min/1.73 m²).

INTERPRETATION: Knowledge of the pharmacology of diuretics is crucial to the rational use of diuretics in renal disease. Dose titration under close clinical monitoring and an optimal dosage interval make it possible to find the lowest possible effective dose and reduce the occurrence of side effects.
