Rostafuroxin potently inhibits binding of endogenous ouabain to the Na+/K+ ATPase (IC50 = 1.7 µM) through the Src-epidermal growth factor receptor (EGFR)-dependent signaling pathway.{33528} This blocks the ouabain-dependent increase in Na+/K+ ATPase activity. In cultured renal cells where the Na+/K+ ATPase is upregulated or has increased activity, rostafuroxin normalizes mRNA levels and Na+/K+ ATPase activity.{33530} At very low doses (1 and 10 µg/kg for 5-6 weeks) in Milan-hypertensive rats, it decreased the development of hypertension.{33531} In a Phase II clinical study, rostafuroxin did not reduce blood pressure in human patients at doses of 0.05-5.0 mg/d.{33532}
