Spironolactone can also have numerous other interactions, most commonly with other cardiac and blood pressure medications, for instance digoxin. [ 8 ] Licorice , which has indirect mineralocorticoid activity by inhibiting mineralocorticoid metabolism, has been found to inhibit the antimineralocorticoid effects of spironolactone.
Refractory hypertension (RfHTN) is hypertension, a high blood pressure, that remains uncontrolled on maximal or near-maximal therapy, that includes the use of ≥5 antihypertensive agents of different classes. [1] Agents used include a long-acting thiazide-like diuretic (such as chlorthalidone) and spironolactone. [2]
Aldosterone binds to aldosterone receptors (mineralocorticoid receptors) increasing sodium reabsorption in an effort to increase blood pressure and improve fluid status in the body. When excessive sodium reabsorption occurs, there is an increasing loss of K + in the urine and can lead to clinically significant decreases, termed hypokalemia .
Spironolactone has been identified as an inhibitor of NRG1‐ERBB4 signaling. [142] Spironolactone has been found to act as a potent inhibitor of the pannexin 1 channel, and this action appears to be involved in its antihypertensive effects independently of MR antagonism. [143] Spironolactone has been found to block hERG channels. [144]

However, spironolactone is metabolized to three active metabolites, which give it prolonged activity (13.8 – 16. 5 hours). Spironolactone has a long half-life and is excreted 47-51% through kidneys. Patients with chronic kidney disease therefore require close monitoring when taking the drug. Spironolactone is also eliminated through feces (35-41%

Antihypertensive agents comprise multiple classes of compounds that are intended to manage hypertension (high blood pressure). Antihypertensive therapy aims to maintain a blood pressure goal of <140/90 mmHg in all patients, as well as to prevent the progression or recurrence of cardiovascular diseases (CVD) in hypertensive patients with established CVD.
