How do loop diuretics act?
In the thick ascending limb of the loop of Henle, NaCl reabsorption is mediated by a Na+/2Cl-/K+ cotransport system, present in the luminal membrane of this nephron segment. Loop diuretics such as furosemide (frusemide), piretanide, bumetanide and torasemide bind reversibly to this carrier protein, thus reducing or abolishing NaCl reabsorption. This leads to a decrease in interstitial hypertoni...
متن کاملLoop Diuretics in Clinical Practice
Diuretics are commonly used to control edema across various clinical fields. Diuretics inhibit sodium reabsorption in specific renal tubules, resulting in increased urinary sodium and water excretion. Loop diuretics are the most potent diuretics. In this article, we review five important aspects of loop diuretics, in particular furosemide, which must be considered when prescribing this medicine...
متن کاملVascular effects of loop diuretics.
Although it is generally believed that the beneficial effect of loop diuretics is the result of a rapid increase in diuresis, substantial evidence, from a large number of in vitro and in vivo experiments, has accumulated showing that administration of furosemide causes direct vascular effects, which probably contribute to its acute clinical effects. Several mechanisms are involved in the vascul...
متن کاملResponsiveness to loop diuretics in heart failure.
Loop diuretics are the most commonly used drugs in the management of pulmonary and systemic congestion in patients with acute decompensated heart failure (ADHF), as well as chronic congestive HF. The diuresis results from blockade of the Na+–K+–Cl2 co-transporter in the ascending limb of the loop of Henle. The pharmacodynamics of loop diuretics are illustrated in Figure 1, and are best describe...
متن کاملOliguria, volume overload, and loop diuretics.
Acute kidney injury (AKI) is commonly and increasingly encountered in patients with critical illness. In the past, epidemiologic studies have consistently found that oliguria further increases the risk of death from AKI. Compared with patients outside the intensive care unit (ICU), critically ill patients are more likely to have volume overload as a result of impaired solute and water excretion...
