  • Single Dose PK for eplerenone: Cmax, Tmax, and AUCtau; Multiple Dose PK for eplerenone: Cmax(ss), Tmax(ss), AUC(,tau,ss), half life, Cmin(ss), Cave(ss), accumulation ratios AUC(tau,ss)/AUC(tau,sd) and Cmax(ss)/Cmax(sd). [ Time Frame: 13 days ]
  • Safety and tolerability of eplerenone as determined by adverse event reporting, clinical laboratory results, vital signs (supine blood pressure and heart rate), physical examinations and ECGs. [ Time Frame: 13 days ]
  • Change from baseline (Day 0) to Day 8 in exploratory mRNA gene expression biomarkers (SGK1: Serum/glucocorticoid regulated kinase 1 gene, ENaCα: Epithelial Sodium Channel alpha subunit, ENaCγ: Epithelial Sodium Channel gamma subunit, [ Time Frame: 9 days ]
  • MR: Mineralcorticoid Receptor, ACTβ: Beta Actin) after administration of eplerenone or placebo. These results will not be included in the study report. [ Time Frame: 9 days ]
