Background:
Mineralocorticoid receptor antagonists are a second-line class of antihypertensive drugs,
which have been accounted for as the optimal add-on therapy in the triple algorithm for the management of resistant
hypertension.
Objectives:
To assess the effects of mineralocorticoid receptor antagonists in the treatment of patients with essential
hypertension and resistant hypertension.
Method:
We conducted a meticulous review of the literature and comprehensive identification of the clinical
trials assessing the efficacy of mineralocorticoid receptor antagonists in individuals with primary and resistant
hypertension.
Results:
MRAs have been thoroughly tested in several clinical studies in relevance to blood pressure lowering
effects, over the last six decades. Accumulating data observed that MRAs resulted in a significant reduction in
blood pressure level in patients with resistant hypertension. In addition, spironolactone was found to beneficially
affect the management of resistant hypertension.
Conclusion:
Mineralocorticoid receptor antagonists exert a significant antihypertensive effect. Future welldesigned
randomized controlled studies are greatly needed to address crucial clinical aspects in the field.
