Administration
Administer with or without food.
Administer at least 3 hours before or 3 hours after other oral medications.
Do not administer in its dry form.
Do not heat (e.g., microwave) or add to heated food or liquids.
Prepare each dose immediately prior to administration.
Measure one-third cup of water, other beverage, or soft food (e.g., apple sauce, yogurt, pudding). Pour half of the water, other beverage, or soft food into a glass.
Empty the entire contents of the packet(s) into the glass and stir thoroughly.

Mechanism Of Action
Patiromer is a cation exchange polymer that contains a calcium-sorbitol counterion. Fecal potassium excretion is increased through binding of potassium in the gastrointestinal lumen, with its principle site of action being the colon. Binding of potassium reduces the concentration of free potassium in the gastrointestinal lumen, resulting in a reduction of serum potassium concentrations.
Pharmacokinetics
Patiromer is administered orally. Results from animal pharmacokinetic studies show patiromer is not systemically absorbed and is excreted in the feces. Radiographic analysis in animals demonstrated that patiromer stays in the gastrointestinal tract, with no detectable level of radioactivity in any other tissues or organs.
Among 25 patients with hyperkalemia and chronic kidney disease given a controlled potassium diet for 3 days followed by 16.8 g patiromer daily (in divided doses) while continuing the controlled diet for 2 days, a statistically significant reduction in serum potassium (-0.2 mEq/L) was observed 7 hours after the first patiromer dose. Serum potassium concentrations continued to decrease during the 2-day treatment period (-0.8 mEq/L at 48 hours after the first dose). Potassium concentrations remained stable for 24 hours after the last patiromer dose and then increased during the 4-day observation period following patiromer discontinuation.
Affected cytochrome P450 isoenzymes and transporters: none
Pregnancy And Lactation
Patiromer is not absorbed systemically following oral administration. Maternal use during pregnancy is not expected to result in fetal risk.
According to the manufacturer, patiromer is not absorbed systemically by the mother; breastfeeding is not expected to result in risk to the infant. Consider the benefits of breast-feeding, the risk of infant drug exposure, and the risk of an untreated or inadequately treated condition. If a breast-feeding infant experiences an adverse effect related to a maternally ingested drug, health care providers are encouraged to report the adverse effect to the FDA.
