🔬 How This Medicine Works (Pharmacology)

Pharmacokinetics

AbsorptionThis medicine is administered intravenously, so absorption from the gastrointestinal tract is not applicable. The iron isomaltoside complex is directly available in the bloodstream for uptake by the reticuloendothelial system.
DistributionAfter intravenous administration, the iron isomaltoside complex is distributed primarily to the reticuloendothelial system, including the liver, spleen, and bone marrow. Iron is then transported by transferrin to sites of erythropoiesis.
Protein BindingIron released from the complex binds to transferrin in the plasma. The iron isomaltoside complex itself is not significantly protein-bound before uptake by macrophages.
MetabolismThe iron isomaltoside complex is metabolised in the reticuloendothelial system, where the carbohydrate carrier is broken down and iron is released. There is no significant hepatic metabolism of the iron itself.
Half-LifeThe elimination half-life of the iron isomaltoside complex is approximately 20 to 24 hours, but this can vary based on individual patient factors and iron status.
ExcretionExcess iron is primarily excreted in the faeces via bile after being taken up by the liver. Small amounts may be lost through urine and sweat. The body does not have an active mechanism to excrete large amounts of iron, so overload can occur with excessive dosing.
BioavailabilityBioavailability is 100% because this medicine is administered intravenously, bypassing gastrointestinal absorption.
Onset of ActionThe onset of action for correcting anaemia is gradual. Haemoglobin levels typically begin to rise within 1 to 2 weeks after administration, with maximum effect seen after 3 to 4 weeks.
Peak Plasma TimePeak plasma concentration of the iron isomaltoside complex occurs at the end of the intravenous infusion, typically within 15 to 30 minutes after administration.
Duration of ActionThe effect of a single dose on iron stores can last for several weeks to months, depending on the dose and the patient's iron requirements. Repeated doses may be needed to fully replenish iron stores.

How It Works

This medicine works by delivering iron isomaltoside, a stable iron-carbohydrate complex, directly into the bloodstream. The complex is taken up by macrophages in the reticuloendothelial system, where iron is released from the carbohydrate carrier and either stored as ferritin or transported by transferrin to the bone marrow for haemoglobin synthesis. This process replenishes iron stores and supports the production of healthy red blood cells, correcting anaemia over time.

Mechanism Steps

1
Intravenous administration: This medicine is injected intravenously, delivering the iron isomaltoside complex directly into the bloodstream.
2
Uptake by reticuloendothelial system: The iron-carbohydrate complex is recognised and taken up by macrophages in the liver, spleen, and bone marrow.
3
Release of iron: Inside the macrophages, iron is released from the isomaltoside carrier and enters the intracellular iron pool.
4
Transport and storage: Iron is either stored as ferritin or exported to transferrin for transport to the bone marrow.
5
Erythropoiesis support: In the bone marrow, iron is incorporated into haemoglobin, supporting the production of new red blood cells and correcting anaemia.

Dosage Information

Adult DosageThe dose of this medicine is individualised by a qualified clinician based on the patient's iron deficit, body weight, and clinical condition. A common approach is to calculate the total iron requirement using the Ganzoni formula or similar, and administer as a single intravenous infusion or in divided doses. Doses may range from 500 mg to 1000 mg per infusion, not exceeding 20 mg/kg of body weight. Dose must be individualized by a qualified clinician based on indication, age, weight, renal and hepatic function.
Pediatric DosagePediatric dosing is not established from available information. Consult a pediatrician.
Elderly DosageElderly patients may be more susceptible to adverse effects and should be monitored closely. Dose adjustments are not typically required based on age alone, but individualised dosing based on renal and hepatic function is advised.
Renal ImpairmentNo specific dose adjustment is required for renal impairment, but this medicine should be used with caution in patients with severe renal impairment. Monitor renal function and iron status closely.
Hepatic ImpairmentNo specific dose adjustment is required for hepatic impairment, but this medicine should be used with caution in patients with severe liver disease. Monitor liver function and iron status.
Maximum Daily DoseThe maximum single dose should not exceed 20 mg/kg of body weight. The maximum cumulative dose depends on the patient's iron deficit and should be determined by a clinician.
