Rostafuroxin is a digitoxigenin analog that has been shown to lower blood pressure in an animal model of hypertension.^[1] It modulates the effects of the enzyme Na⁺/K⁺-ATPase,^[1] which maintains sodium and potassium ion gradients across plasma membranes. Rostafuroxin is being studied in clinical trials for the treatment of essential hypertension.^[2]^[3]
