Generic Name: iron polymaltose
Product Name: Ferrum H
Indication: What Ferrum H is used for
Ferrum H provides a source of iron that can help to replenish a shortage of iron in patients with iron deficiency.
Ferrum H is used when dosage by mouth is impractical or contraindicated and when disturbances in the gastrointestinal tract make absorption difficult or uncertain.
Action: How Ferrum H works
Ferrum H is an aqueous, approximately isotonic solution for intramuscular injection.
When injected intramuscularly the iron polymaltose evokes a local inflammatory response and is transported via the lymphatics to the regional lymph nodes without being broken down (reactive absorption). It then enters the blood, reaching its maximum concentration in about 24 hours. The circulating iron polymaltose is taken up by the cells of the reticuloendothelial system, which slowly ionise it to Fe3+ and polymaltose. The majority of Fe3+ is bound to transferrin and transported to the bone marrow where it is incorporated into haemoglobin, the remainder is contained within the storage forms, haemosiderin and ferritin, or incorporated into myoglobin or haem-containing enzymes. Only very small amounts of iron are excreted. The conservation of body iron and the lack of an excretory mechanism for excess iron may lead to iron overload if iron intake is excessive. Polymaltose is either metabolised or excreted.
Ferrum H contains the active ingredient iron polymaltose complex. It also contains the inactive ingredients water for injections, sodium hydroxide, hydrochloric acid.
