Inclusion criteria

• All patients who were randomized and completed all study visits of the preceding double-blind trial with the fixed dose combination (502.261) who meet the following criteria:

• Serum creatinine > 2.3 mg/dL
• Clinically relevant sodium depletion, hyperkalemia, or hypokalemia at baseline
