Aldosterone is increased at low sodium intakes, but the rate of increase of plasma aldosterone as potassium rises in the serum is not much lower at high sodium intakes than it is at low. Thus, potassium is strongly regulated at all sodium intakes by aldosterone when the supply of potassium is adequate, which it usually is in hunter-gatherer diets.
Therefore, it is recommended that people using this medication avoid potassium supplements and salt substitutes containing potassium. [169] Physicians must be careful to monitor potassium levels in both males and females who are taking spironolactone as a diuretic, especially during the first twelve months of use and whenever the dosage is ...
Low potassium is caused by increased excretion of potassium, decreased consumption of potassium rich foods, movement of potassium into the cells, or certain endocrine diseases. [3] Excretion is the most common cause of hypokalemia and can be caused by diuretic use, metabolic acidosis , diabetic ketoacidosis , hyperaldosteronism , and renal ...
The same year, 1959, spironolactone was launched as a potassium-sparing diuretic. It became clear years later that aldosterone antagonists inhibit a specific receptor protein. This protein has high affinity for aldosterone but also for cortisol in humans and corticosterone in mice and rats. For this reason, aldosterone antagonists were called ...
In the adrenal cortex, angiotensin II acts to cause the release of aldosterone. Aldosterone acts on the tubules (e.g., the distal convoluted tubules and the cortical collecting ducts) in the kidneys, causing them to reabsorb more sodium and water from the urine. This increases blood volume and, therefore, increases blood pressure.
In sweat glands potassium elimination is quite similar to the kidney; its excretion is also controlled by aldosterone. [ 6 ] Regulation of serum potassium is a function of intake, appropriate distribution between intracellular and extracellular compartments, and effective bodily excretion.
Thus, dysfunction of the pituitary gland or the hypothalamus does not affect the production of aldosterone. [2] [3] However, in primary adrenal insufficiency, damage to the adrenal cortex (e.g. autoimmune adrenalitis a.k.a. Addison's disease) can lead to destruction of the zona glomerulosa and therefore a loss of aldosterone production.
Hence, aldosterone antagonists are potassium (K +) sparing diuretics. The medication has a slightly delayed onset of action , and so it takes several days for diuresis to occur since the MR is a nuclear receptor which works through regulating gene transcription and gene expression .
