Oubain, but not digoxin, induces hypertension; digoxin and digitoxin reverse ouabain-induced hypertension. Rats were infused with vehicle (■), ouabain, 15 μg/kg/day (▼), or digoxin, 30 μg/kg/day (▲), for 42 days. From days 35 to 42, three groups of 8 ouabain-infused rats received a secondary infusion of digoxin, 30 μg/kg/day (●), digitoxin, 30 μg/kg/day (○), or vehicle (▼). Mean blood pressures (MBP) were obtained by tail cuff at weekly intervals or as indicated. *P<0.05 vs ouabain; ***P<0.001 vs ouabain; #P<0.005 vs vehicle; **P<0.001 vs digoxin.
