Patiromer in the Treatment of Hyperkalemia in Patients With Hypertension and Diabetic Nephropathy (AMETHYST-DN)

Summary

This study determined the optimal starting dose of patiromer in treating hyperkalemia in participants with hypertension and diabetic nephropathy who were already receiving ACEI and/or ARB drugs, with or without spironolactone. This study also evaluated the efficacy and safety of patiromer and the long term use of patiromer.
