Ferric Citrate

Ferric Citrate is a phosphate binder indicated for the control of serum phosphorus levels in adult patients with chronic kidney disease on dialysis. Ferric Citrate is an iron replacement product indicated for the treatment of iron deficiency anemia in adult patients with chronic kidney disease not on dialysis.

Hyperphosphatemia in chronic kidney disease on dialysis: Ferric iron binds dietary phosphate in the GI tract and precipitates as ferric phosphate. This compound is insoluble and is excreted in the stool. By binding phosphate in the GI tract and decreasing absorption, ferric citrate lowers the phosphate concentration in the serum.

Iron deficiency anemia in chronic kidney disease not on dialysis: Ferric iron is reduced from the ferric to the ferrous form by ferric reductase in the GI tract. After transport through the enterocytes into the blood, oxidized ferric iron circulates bound to the plasma protein transferrin, and can be incorporated into hemoglobin.

Hyperphosphatemia in chronic kidney disease on dialysis:

• Starting dose is 2 tablets orally 3 times per day with meals.
• Adjust dose by 1 to 2 tablets as needed to maintain serumphosphorus at target levels, up to a maximum of 12 tablets daily. Dose can be titrated at 1-week or longer intervals.

Iron deficiency anemia in chronic kidney disease not on dialysis:

• Starting dose is 1 tablet orally 3 times per day with meals.
• Adjust dose as needed to achieve and maintain hemoglobin goal, up to a maximum of 12 tablets daily.

When clinically significant drug interactions are expected, consider separation of the timing of administration. Consider monitoring clinical responses or blood levels of the concomitant medication.

Ferric Citrate is contraindicated in patients with iron overload syndromes.

Most common adverse reactions (incidence ≥5%) are discolored feces, diarrhea, constipation, nausea, vomiting, cough, abdominal pain, and hyperkalemia.

There are no available data on Ferric Citrate use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. There are no human data regarding the effect of Ferric Citrate in human milk, the effects on the breastfed child, or the effects on milk production.

No data are available regarding overdose of Ferric Citrate in patients. In patients with chronic kidney disease, the maximum dose studied was 2,520 mg ferric iron (12 tablets of Ferric Citrate) per day. Iron absorption from Ferric Citrate may lead to excessive elevations in iron stores, especially when concomitant intravenous iron is used.

Keep below 30°C temperature, away from light & moisture. Keep out of the reach of children.
