Brief Summary

When a patient arrives to an emergency department and is found to have an elevated potassium level in the blood, there is no one standardized treatment, therefore it is not known if one treatment is superior to other. The purpose of this study is to help determine if a drug called patiromer (already approved by the FDA) can help lower potassium levels while patients are in the emergency department.

Detailed Description

Given the lack of consistency in hyperkalemia treatment in the ED and the high cost of emergent dialysis, there is a need for the development and systematic evaluation of a treatment protocol to shift potassium into the cells followed by the removal of potassium from the body with a potassium binder.. The present study will use a systematic approach to shifting potassium into the cells followed by binding potassium in the gastrointestinal tract in hyperkalemic patients presenting to the ED. Study subjects will receive patiromer or placebo to determine if patiromer reduces the need for additional medical intervention for the management of hyperkalemia in patients initially treated with IV and inhaled therapy in the ED.

Upon enrollment, patiromer will be administered at a dose selected because of its safety and efficacy shown in a pilot study named REDUCE.

Up to 300 patients will be enrolled and followed for up to 14 days, and potassium levels will be measured at pre-determined intervals to assess drug's impact. concomitant medications will be recorded to help determine if study drug helped, not just lower hyperkalemia, but also decrease the number of total interventions needed to reach a normal potassium level.
