Iron is an essential constituent of the body being necessary for haemoglobin formation and for the oxidative processes of living tissues. Iron salts should only be given for the treatment and as prophylaxis of Iron deficiency anaemia. Iron deficiency anaemias are most often the result of chronic haemorrhage, nutritional deficiency, pregnancy or parasite infestation or malabsorption of iron.
A deficiency of Folic acid typically during pregnancy has long been known to cause a megaloblastic anaemia. The vitamin is not storable in the body and the combination of fetal demand during pregnancy and malnutrition can lead to a deficiency, hence anaemia. It has been observed that the rapid production of red blood cells following treatment with iron may deplete body folate if there is inadequate intake; combination of folic acid and ferrous fumerate avoids the complication. Iron and Folic acid are absorbed in the proximal small intestine particularly the duodenum. Ferrous Fumerate & Folic acid supplements replenish iron deficiency. Thereby arresting the anaemia process. Absorbed iron is taken upto the bone marrow's tissues that form blood cells where it is used to synthesize haemoglobin.

Uses
For treatment of iron deficiency and prevention of concomitant Folic acid deficiency in adults. For maintenance of maternal haematopoiesis during pregnancy particularly when diet is abnormal or substandard.
Aristofol-Fe is also used to associated treatment for these conditions: Anaemia folate deficiency, Folate deficiency, Iron Deficiency (ID), Iron Deficiency Anemia (IDA), Latent Iron Deficiency, Neural Tube Defects (NTDs), Vitamin Deficiency, Methotrexate toxicity, Nutritional supplementation
How Aristofol-Fe works
Folic acid, as it is biochemically inactive, is converted to tetrahydrofolic acid and methyltetrahydrofolate by dihydrofolate reductase (DHFR). These folic acid congeners are transported across cells by receptor-mediated endocytosis where they are needed to maintain normal erythropoiesis, synthesize purine and thymidylate nucleic acids, interconvert amino acids, methylate tRNA, and generate and use formate. Using vitamin B12 as a cofactor, folic acid can normalize high homocysteine levels by remethylation of homocysteine to methionine via methionine synthetase.
Dosage
Aristofol-Fe dosage
In anaemia: The usual dose is one tablet or capsule daily.
In severe or refractory iron deficiency anaemia: The usual dose is one tablet or capsule twice daily may be given.
In Pregnancy, it is recommended that the dose should be started at the first antenatal consultation and continued until 3 months after delivery.
May be taken with or without food.
Side Effects
Gastric distress, abdominal cramps, diarrhoea, allergic reaction.
Toxicity
IPR-MUS LD50 85 mg/kg,IVN-GPG LD50 120 mg/kg, IVN-MUS LD50 239 mg/kg, IVN-RAT LD50 500 mg/kg, IVN-RBT LD50 410 mg/kg
Precaution
Administration of Ferrous Fumerate & Folic acid during the first trimester of pregnancy may be undesirable. Very few pregnant women are not protected by physiological doses of Folic acid. If anaemia is developed despite prophylaxis with Ferrous Fumerate & Folic acid, patients should be investigated further. Some postgastrectomy patients show poor absorption of iron. Care is needed when treating patients with peptic ulcer.
Interaction
When Ferrous Fumerate & Folic acid combination and Tetracycline are taken concomitantly, absorption of both drugs are reduced. Concurrent administration of antacid may reduce absorption of iron. Serum anticonvulsant levels may be reduced by administration of folate.
Volume of Distribution
Tetrahydrofolic acid derivatives are distributed to all body tissues but are stored primarily in the liver.
Elimination Route
Folic acid is absorbed rapidly from the small intestine, primarily from the proximal portion. Naturally occurring conjugated folates are reduced enzymatically to folic acid in the gastrointestinal tract prior to absorption. Folic acid appears in the plasma approximately 15 to 30 minutes after an oral dose; peak levels are generally reached within 1 hour.
Elimination Route
After a single oral dose of 100 mcg of folic acid in a limited number of normal adults, only a trace amount of the drug appeared in the urine. An oral dose of 5 mg in 1 study and a dose of 40 mcg/kg of body weight in another study resulted in approximately 50% of the dose appearing in the urine. After a single oral dose of 15 mg, up to 90% of the dose was recovered in the urine. A majority of the metabolic products appeared in the urine after 6 hours; excretion was generally complete within 24 hours. Small amounts of orally administered folic acid have also been recovered in the feces. Folic acid is also excreted in the milk of lactating mothers.
Pregnancy & Breastfeeding use
There is no contraindication in pregnancy and lactation.
Contraindication
This is contraindicated in patients with pernicious anaemia and anaemia other than those due to iron deficiency. The nature and causes of anaemia should be established. Absorption of Ferrous Fumerate & Folic acid is inhibited by Magnesium trisillicate and Antacid containing carbonate.
Storage Condition
Store at 15-30° C.
