The causes of diuretic resistance include poor adherence to drug therapy or dietary sodium restriction, pharmacokinetic issues, and compensatory increases in sodium reabsorption in nephron sites that are not blocked by the diuretic.

What causes loop diuretics?
Background. The loop diuretics act by inhibition of the sodium-potassium-chloride symporter present in the thick ascending limb of the loop of Henle causing an inhibition of sodium reuptake.
What do loop diuretics do to potassium?
When used on their own, potassium-sparing diureticspotassium-sparing diureticsPotassium-sparing diuretics refers to drugs that cause diuresis without causing potassium loss in the urine. They are typically used as an adjunct in management of hypertension, cirrhosis, and congestive heart failure. The steroidal aldosterone antagonists can also be used for treatment of primary hyperaldosteronism.https://en.wikipedia.org › wiki › Potassium-sparing_diureticPotassium-sparing diuretic - Wikipedia are weak diuretics. Loop diuretics and thiazide diuretics are stronger than potassium-sparing diuretics with regard to making the kidneys pass out more fluid. However, they also increase the amount of potassium passed out of the body through the kidneys.
How does diuretic resistance occur?
Pathophysiological mechanisms of diuretic resistance include an inappropriately high daily salt intake that exceeds the acute diuretic-induced salt loss, hyponatremia or hypokalemic, hypochloremic metabolic alkalosis, and reflex activation of the renal nerves.
Diuretic Resistance
How do you fix a diuretic resistance?
- Dietary Sodium Intake and Compliance to Therapy. ... - Combined Diuretic Therapy. ... - Intermittent versus Continuous Intravenous Administration of Bolus Loop Diuretics Administration. ... - Hypertonic Saline Infusion in Addition to High-Dose LDs. ... - Role of Vasopressin Secretion in Chronic HF.
How are loop diuretics secreted?
Loop diuretics are highly protein bound and therefore have a low volume of distribution. The protein bound nature of the loop diuretic molecules causes it to be secreted via several transporter molecules along luminal wall of the proximal convoluted tubules to be able to exert its function.
Does loop diuretics cause hyperkalemia?
Loop diuretics also have the potential to cause ototoxicity and hearing loss. Of note hypokalemia can cause ventricular arrhythmias and muscular weakness. Spironolactone's primary adverse effect is hyperkalemia, especially in elderly patients and those with chronic kidney disease.
Diuretic Resistance
What causes diuretics to stop working?
The causes of diuretic resistance include poor adherence to drug therapy or dietary sodium restriction, pharmacokinetic issues, and compensatory increases in sodium reabsorption in nephron sites that are not blocked by the diuretic.
What is diuretic braking?
The third mechanism is "diuretic braking," the decrease in a patient's response to a diuretic after receiving the first dose. In other words, the magnitude of response to each administered dose of diuretic declines with time.
Diuretic Resistance In Cardionephrology
What is the mechanism of action for diuretic?
They act by diminishing sodium reabsorption at different sites in the nephron, thereby increasing urinary sodium and water losses. A second class of diuretics, sometimes termed aquaretics, instead inhibit water reabsorption by blocking vasopressin receptors along the connecting tubule and collecting duct.
Can you become resistant to diuretics?
Pathophysiological mechanisms of diuretic resistance include an inappropriately high daily salt intake that exceeds the acute diuretic-induced salt loss, hyponatremia or hypokalemic, hypochloremic metabolic alkalosis, and reflex activation of the renal nerves.
