Aldosterone Antagonists Mechanism Of Action. Spironolactone a competitive aldosterone receptor antagonist ARA has traditionally been the treatment of first choice in idiopathic hyperaldosteronism IHA and for preoperative management of aldosterone producing adenoma APA. Aldosterone is a steroid hormone and is the primary physiological mineralocorticoid secreted by the adrenal cortex. Mechanism of action spironolactone Spironolactone is a competitive antagonist for aldosterone on its intracellular receptors. Although glucocorticoid secretion is regulated primarily by pituitary ACTH adrenocorticotropic hormone Ang II acts as the primary stimulus for aldosterone secretion.
