- Phase: PHASE3
- Number of Arms: 5.0

Eligibility Criteria:
Inclusion Criteria:~* Provision of written informed consent.~* Over 18 years of age.~* Two consecutive i-STAT potassium values, measured 60-minutes apart, both ≥5.1 mmol/l and measured within 1 day of the first ZS dose on AP Study Day 1.~* Ability to have repeated blood draws or effective venous catheterization.~* Women of childbearing potential must be using two forms of medically acceptable contraception (at least one barrier method) and have a negative pregnancy test at AP Study Day 1. Women who are surgically sterile or those who are post-menopausal for at least 2 years are not considered to be of childbearing potential.~Exclusion Criteria:~* Pseudohyperkalemia signs and symptoms, such as excessive fist clenching hemolyzed blood specimen, history of severe leukocytosis or thrombocytosis.~* Subjects treated with lactulose, Xifaxan or other non-absorbed antibiotics for hyperammonemia within 7 days prior to the first dose of study drug.~* Subjects treated with resins (such as sevelamer acetate or sodium polystyrene sulfonate \[SPS; e.g. Kayexalate®\]), calcium acetate, calcium carbonate, or lanthanum carbonate, within 7 days prior to the first dose of study drug.~* Subjects with a life expectancy of less than 3 months.~* Subjects who are severely physically or mentally incapacitated and who in the opinion of investigator are unable to perform the subjects' tasks associated with the protocol.~* Women who are pregnant, lactating, or planning to become pregnant.~* Subjects with diabetic ketoacidosis.~* Presence of any condition which, in the opinion of the investigator, places the subject at undue risk or potentially jeopardizes the quality of the data to be generated.~* Known hypersensitivity or previous anaphylaxis to ZS or to components thereof.~* Randomization into the previous ZS-002 or ZS-003 studies.~* Treatment with a drug or device within the last 30 days that has not received regulatory approval at the time of study entry.~* Subjects with cardiac arrhythmias that require immediate treatment.~* Subjects on dialysis.
