Ferrous fumarate Chemical Properties,Usage,Production

Description

Ferrous fumarate is the ferrous salt form of fumarate. One of its most important applications is being used as iron supplements for the treatment of iron deficiency and anemia. It has been demonstrated that application of ferrous sulfate drops or a single daily dose of microencapsulated ferrous fumarate sprinkles plus ascorbic acid both result in successful treatment of anemia without remarkable side effects. However, recent studies have also shown that compared to other iron supplements, ferrous fumarate has a highest rate of inducing adverse reactions such as erosive mucosal injury in the gastrointestinal tract as well as nausea, vomiting and epigastric discomfort.

Chemical Properties

Ferrous fumarate (iron(II)fumarate, C4H2Fe04) is an odorless, reddish-orange to reddish-brown powder. It may contain soft lumps that produce a yellow streak when crushed. It is prepared by admixing hot solutions of ferrous sulfate and sodium fumarate.

Originator

Toleron,Mallinckrodt Inc.,US,1957

Uses

Ferrous Fumarate is a reddish orange to red-brown powder that is a source of iron. it has high bioavailability and can be used in foods where the red color can be masked. it contains approximately 33% iron. it is used as a dietary supplement in breakfast cereals, poultry stuffing, enriched flour, and instant drinks.

Uses

Ferrous fumarate is available as a syrup and may be useful in small children for the treatment and prophylaxis of iron deficiency. Iron(II) Fumarate is a a chemical used in the treatment of iron deficiency. More commonly used for this treatment is Ferrous Sulfate however Iron(II) Fumarate does maintain similar absorption profiles.

Uses

Iron(II) fumarate is used as dietary Supplement, nutrient, iron source in foods and pharmaceuticals, as animal feed additive and in infant formulas.

Definition

Ferrous fumarate is a dicarboxylic acid. Anhydrous salt of a combination of ferrous iron and fumaric acid, stable, odorless, substantially tasteless. Reddish-brown, anhydrous powder, contains 33% iron by weight, does not melt at temperatures up to 280C, insoluble in alcohol, very slightly solubility. It is used in treatment of iron deficiency anemia.

Manufacturing Process

Sodium carbonate (53.5 pounds of Na2CO3-H2O) was dissolved in water (40 to 45 gallons) and fumaric acid (50 pounds) was added slowly. During the addition the solution was stirred and heated. The resulting solution of sodium fumarate, having a pH of 6.8, was added slowly with mixing to a solution of ferrous sulfate (118 pounds FeSO4-7H2O in 33 gallons of water) having a pH of 3.3, both solutions being maintained at or near boiling temperature during the mixing. The resulting slurry of reddish-brown anhydrous ferrous fumarate was filtered and washed in a centrifuge and dried in a tray drier (15 hours at 110°C). Yield: 63 pounds, 86% of theory. Calculated for FeC4H2O4: Fe, 32.9%. Found: Fe, 32.6%. Only 0.2% of ferric iron (Fe+++) was found.

Therapeutic Function

Hematinic

General Description

Ferrous fumarate is a commonly used inexpensive substitute for other forms of iron, that is employed as a food iron fortificant.

Flammability and Explosibility

Not classified

Clinical Use

Iron deficiency anaemia

Safety Profile

Poison by intraperitoneal route. Moderately toxic by ingestion and subcutaneous routes. Human systemic effects by ingestion: dyspnea, nausea or vomiting, somnolence. When heated to decomposition it emits acrid smoke and irritating fumes. See also FUMRIC ACID.

Drug interactions

Potentially hazardous interactions with other drugs
Antibacterials: reduced absorption of 4-quinolones and tetracyclines.
Dimercaprol: avoid concomitant use.
Mycophenolate: may significantly reduce absorption of mycophenolate.

Metabolism

Following absorption, the majority of iron is bound to transferrin and transported to the bone marrow where it is incorporated into haemoglobin. The remainder is stored within ferritin or haemosiderin or is incorporated into myoglobin with smaller amounts occurring in haemcontaining enzymes or in plasma bound to transferrin. Only very small amounts are excreted as the body reabsorbs the iron after the haemoglobin has broken down.
