==Overview==
==Overview==
The optimal therapy for primary hyperaldosteronism depends on the [[etiology]] of hyperaldosteronism. Medical therapy is indicated for bilateral [[Adrenal gland|adrenal]] [[hyperplasia]], and all ambiguous causes of primary hyperaldosteronism.
==Medical Therapy==
==Medical Therapy==
The high blood pressure can be controlled with [[spironolactone]] (a [[diuretic]] that counteracts the actions of [[aldosterone]]) and other [[antihypertensives]].
 
=== Indications ===
Medical therapy is indicated for:
* Bilateral [[Adrenal gland|adrenal]] [[hyperplasia]]
* All ambiguous causes of primary hyperaldosteronism.
The following agents may be used to medical management of primary hyperaldosteronism:
