Pharmacology

Indication

For the replacement of iron to maintain hemoglobin in adult patients with hemodialysis-dependent chronic kidney disease (HDD- CKD).

Structured Indications
Pharmacodynamics
Not Available
Mechanism of action

Iron delivered into the circulation binds to transferrin for transport to erythroid precursor cells to be incorporated into hemoglobin.

Absorption

The results of the present studies show that micronised, dispersible ferric pyrophosphate is as well absorbed as ferrous sulfate in adults. The absorption of iron depends upon the route of entry. The tissue that first clears parenterally administered iron from the bloodstream determines the bioavailability.

Volume of distribution

Exists in humans almost exclusively complexed to protein or in heme molecules.

Protein binding
Not Available
Metabolism

There is no destructive metabolism of iron because it takes place in a closed system.

Route of elimination

Very little iron is excreted. In normal, healthy adults, some daily loss of iron occurs through normal skin, hair, and nail loss, and GI losses.

Half life

1.48 hours

Clearance
Not Available
Toxicity

Ingestion of less than 40 mg/kg generally does not cause significant toxicity, although mild GI irritation may develop.Mild symptoms are likely to occur with peak iron concentrations greater than 300 mcg/dL, while peak concentrations of more than 500 mcg/dL generally causes severe symptoms.
