Aldosterone is the primary of several endogenous members of the class of mineralocorticoids in humans. [citation needed] Deoxycorticosterone is another important member of this class. Aldosterone tends to promote Na + and water retention, and lower plasma K + concentration by the following mechanisms:
Hypoaldosteronism. Hypoaldosteronism is an endocrinological disorder characterized by decreased levels of the hormone aldosterone. Similarly, isolated hypoaldosteronism is the condition of having lowered aldosterone without corresponding changes in cortisol. [1] (. The two hormones are both produced by the adrenals.)
Mineralocorticoid receptor antagonists decrease the aldosterone effect by binding to the mineralocorticoid receptor inhibiting aldosterone. This leads to higher levels of potassium in serum and increased sodium excretion, resulting in decreased body fluid and lower blood pressure. [5]
“Additionally, vitamin D influences the renin-angiotensin-aldosterone system, a key regulator of blood pressure,” he said. “Adequate vitamin D levels may reduce the activity of this system ...
Aldosterone receptor antagonists, also known as mineralocorticoid receptor antagonist (MRA) can lower blood pressure by blocking the binding of aldosterone to the mineralocorticoid receptor. Spironolactone and eplerenone are MRAs that causes a block in the reabsorption of sodium, resulting in a decrease in blood pressure.
Spironolactone is used in the treatment of hyperaldosteronism (high aldosterone levels or mineralocorticoid excess), for instance primary aldosteronism (Conn's syndrome). [46] Antimineralocorticoids like spironolactone and eplerenone are first-line treatments for hyperaldosteronism. [46]
Beta blocker. Skeletal formula of propranolol, the first clinically successful beta blocker. Beta blockers, also spelled β-blockers, are a class of medications that are predominantly used to manage abnormal heart rhythms (arrhythmia), and to protect the heart from a second heart attack after a first heart attack (secondary prevention). [1]
Adrenal insufficiency is a condition in which the adrenal glands do not produce adequate amounts of steroid hormones.The adrenal glands—also referred to as the adrenal cortex—normally secrete glucocorticoids (primarily cortisol), mineralocorticoids (primarily aldosterone), and androgens.
