Which diuretic causes metabolic alkalosis?

Loop and thiazide diuretics can cause metabolic alkalosis due to increased excretion of chloride in proportion to bicarbonate. This is more common with loop diuretics than thiazide diuretics.

Which diuretic causes metabolic acidosis?

Carbonic anhydrase inhibitors produce less hypokalemia and volume depletion but commonly induce metabolic acidosis that is often symptomatic. The potassium-sparing agents also limit proton excretion, and spironolactone may produce metabolic acidosis.

Which drugs cause metabolic alkalosis?

Metabolic Alkalosis

  • Carbonic Anhydrase Inhibitors.
  • Acids.
  • Potassium-Sparing Diuretics.
  • Angiotensin-Converting Enzyme Inhibitors.
  • Potassium Supplements.
  • Fluid Replacements.
  • Corticosteroids.
  • Nonsteroidal Anti-inflammatory Agents.

What is the most common cause of metabolic alkalosis?

The most common causes are volume depletion (particularly when involving loss of gastric acid and chloride (Cl) due to recurrent vomiting or nasogastric suction) and diuretic use. Metabolic alkalosis involving loss or excess secretion of Cl is termed chloride-responsive.

Can furosemide cause metabolic alkalosis?

Chloruretic agents such as chlorothiazide, furosemide, and their congeners all directly produce the loss of chloride, sodium, and fluid in the urine (12). These losses, in turn, promote metabolic alkalosis by several possible mechanisms.

What is a common side effect of diuretics?

Side effects

Diuretics are generally safe. Side effects include increased urination and sodium loss. Diuretics can also affect blood potassium levels. If you take a thiazide diuretic, your potassium level can drop too low (hypokalemia), which can cause life-threatening problems with your heartbeat.

Why does furosemide cause metabolic alkalosis?

Furosemide acts immediately after administration, causing a rise in urinary output, Na+U and Cl-U concentrations. Loop-diuretic-induced metabolic alkalosis may be due to an increased urinary chloride loss and the associated increase in SIDpl.

How do you fix metabolic alkalosis?

Metabolic alkalosis is corrected with the aldosterone antagonist spironolactone or with other potassium-sparing diuretics (eg, amiloride, triamterene). If the cause of primary hyperaldosteronism is an adrenal adenoma or carcinoma, surgical removal of the tumor should correct the alkalosis.

What are the symptoms of metabolic alkalosis?

Symptoms of alkalosis can include any of the following:

  • Confusion (can progress to stupor or coma)
  • Hand tremor.
  • Lightheadedness.
  • Muscle twitching.
  • Nausea, vomiting.
  • Numbness or tingling in the face, hands, or feet.
  • Prolonged muscle spasms (tetany)

How do I know if I have metabolic alkalosis?

Metabolic alkalosis is diagnosed by measuring serum electrolytes and arterial blood gases. If the etiology of metabolic alkalosis is not clear from the clinical history and physical examination, including drug use and the presence of hypertension, then a urine chloride ion concentration can be obtained.

How does dehydration cause metabolic alkalosis?

Contraction alkalosis – This results from a loss of water in the extracellular space, such as from dehydration. Decreased extracellular volume triggers the renin-angiotensin-aldosterone system, and aldosterone subsequently stimulates reabsorption of sodium (and thus water) within the nephron of the kidney.

What does metabolic alkalosis do to the body?

A reduced blood flow impairs your body’s ability to remove the alkaline bicarbonate ions. Heart, kidney, or liver failure. Metabolic alkalosis can be caused by failure of a major organ, such as your heart, kidney, or liver. This leads to potassium depletion.

What causes elevated bicarbonate?

A high level of bicarbonate in your blood can be from metabolic alkalosis, a condition that causes a pH increase in tissue. Metabolic alkalosis can happen from a loss of acid from your body, such as through vomiting and dehydration.

How does alkalosis affect potassium?

A frequently cited mechanism for these findings is that acidosis causes potassium to move from cells to extracellular fluid (plasma) in exchange for hydrogen ions, and alkalosis causes the reverse movement of potassium and hydrogen ions.

What are the 5 types of diuretics?

Thiazides are the most commonly prescribed diuretics. They’re most often used to treat high blood pressure. These drugs not only decrease fluids, they also cause your blood vessels to relax.

Thiazide diuretics

  • chlorthalidone.
  • hydrochlorothiazide (Microzide)
  • metolazone.
  • indapamide.

How does Diamox help with metabolic alkalosis?

Acetazolamide decreases proximal tubular bicarbonate reabsorption by up to 80% through inhibition of carbonic anhydrase in the luminal borders of renal proximal tubule cells, and it is often effectively used in the treatment of metabolic alkalosis in the ICU.
