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.
