Patiromer Acetate Induced Hypercalcemia: An Unreported Adverse Effect

Abstract EN

Hyperkalemia, a potential life threating condition, is a commonly encountered problem in chronic kidney disease (CKD) patients.

Patiromer acetate, a nonabsorbable cation exchange polymer, is a gastrointestinal agent for chronic therapy in patients with persistent hyperkalemia.

Patiromer is generally well tolerated in patients; common side effects are gastrointestinal, such as diarrhea, constipation, flatulence, and vomiting.

Hypercalcemia, although a theoretical possibility, has not been reported in any major clinical trials.

We present a case of hypercalcemia associated with patiromer acetate used for treatment of hyperkalemia in a stage IV CKD patient.

Clinicians should be aware of the possibility of hypercalcemia while taking patiromer.
