Heinig R , Frantz S , Rollins J , Agarwal R , Pitt B Surprisingly, in a mouse model of glomerulonephritis, podocyte MRKO provided no kidney protection vs. wild-type controls; cystatin C (a marker of kidney function) and histology were similar between groups.48 Contrastingly, myeloid MRKO was renoprotective, with reduced proteinuria vs. wild-type controls.48 Importantly, whereas eplerenone-treated wild-type mice also had reduced proteinuria, unlike myeloid MRKO, eplerenone use was associated with impairment in kaliuresis.48 This is particularly relevant in providing direct evidence of kidney protection by tissue/cell type-selective MR antagonism, without hyperkalaemia.48 Myeloid MRKO has also been shown to be protective against cardiac hypertrophy, fibrosis, and vascular damage. , Cavanaugh K , Mentenich N , McKinlay SM , Muffat-Joly M , Kimmeskamp-Kirschbaum N , O'Neill B , Charpentier F , Beyhoff N Myeloid MRKO has perhaps contributed the most intriguing results to understanding the molecular physiology and pathophysiology of the MR, suggesting a novel immune mediation of inflammatory and fibrotic processes leading to organ dysfunction. As examples, appropriate initial combination therapy may include a beta blocker plus a long-acting ACE inhibitor/ARB in patients who have had a recent myocardial infarction or a loop diuretic plus an ACE inhibitor/ARB or mineralocorticoid receptor antagonist in … , Rouleau J-L , Rey Blas JR , Frydenberg M MRKO studies demonstrated that MR antagonism could play a key role in addressing the residual risk of progression of kidney and heart disease. , Dezsi C Hypertens Res. , Sweitzer NK , Banker ME Examples include progesterone, drospirenone, gestodene, and benidipine.[9].

A challenge in treating sepsis, a potentially life-threatening, systemic inflammatory disorder, is the increase in endothelial permeability that leads to widespread tissue edema and immune cell infiltration. , Higano CS , Gordeev I , Watson AD , Lombes M Combined, these studies should firmly establish the role of finerenone in cardiorenal medicine.

Navaneethan SD , Garcia CG , Viengchareun S , Shao Y , Anderson A Alexandrou ME In fact, over half of the systolic BP-lowering effect was retained 2 weeks after stopping treatment, suggesting that the metabolite-induced haemodynamic effects had persisted especially among patients with moderate-to-advanced CKD.75 Likely, spontaneous recovery from hyperkalaemia may not be expected immediately after spironolactone discontinuation. , Ruilope LM , Hauet T Bayer. , Chen CD , Ballard S Oral tolvaptan is another vasopressin receptor antagonist with … , Delarche N , Gretz N , Schutz G , Solomon SD The Merck Index* Online - search across all of the entries using text (names, classifications) and numerical (melting point, mol weight, boiling point) queries , Kretschmer A , Lewis EF , Palombo G , Landis JR , Okuda Y Le Menuet D However, spironolactone is metabolized to three active metabolites, which give it prolonged activity (13.8 – 16. , Hutyra M Two examples of systems with well-demonstrated perturbation in the setting of HF are abnormalities of myocardial metabolism and of the peripheral skeletal musculature. , Motreff P , Berger S. Terker AS [6] , Oblin M-E In 2016, the Aldosterone Blockade Early After Acute Myocardial Infarction (ALBATROSS; N = 1603) trial was published.30 Patients with acute MI were randomized to receive an MRA regimen with a single intravenous bolus of potassium canrenoate (200 mg) followed by oral spironolactone (25 mg once daily) for 6 months plus SOC or SOC alone. , Yip S , Galinier M , Garg AX There are at least 22 known cofactors that associate with MR72 that determine the full transcriptional response mediated by the MR in a cell-specific manner.68,72 Molecular modelling studies of the finerenone–MR complex suggest that finerenone blocks the MR as a bulky, passive antagonist. , Kenwood CT , Bénitah J-P However, these results must be interpreted with caution as the study was not powered to investigate treatment effects on hard outcomes (Figure 4).86 The primary outcome in ARTS-DN of UACR reduction from baseline to day 90 was found to be dose dependent for finerenone (Figure 4).85 This was statistically significant for the four highest doses of finerenone, with a placebo-corrected UACR reduction of 38% at 20 mg/day.85,Post hoc analysis showed that UACR changes were independent of changes in BP or eGFR, suggesting non-haemodynamic effects.85 There were no differences in the overall incidence of adverse events, including an eGFR reduction of ≥30%, between finerenone and placebo.85 The rate of treatment discontinuation due to hyperkalaemia was low and not dose dependent.85.
