Ferrous Ascorbate + Folic Acid + Zinc

Usage

• This combination is prescribed for the treatment and prevention of iron deficiency anemia, folate deficiency anemia, and zinc deficiency. It is particularly important during pregnancy to prevent neural tube defects in the developing fetus and to support the mother’s increased nutritional needs. It is also used to treat nutritional anemia caused by poor diet, chronic blood loss, or certain medical conditions.

• Pharmacological classification: Nutritional supplement, hematinic.

• Mechanism of action: This combination replenishes depleted iron, folate, and zinc stores. Iron is crucial for hemoglobin synthesis, enabling red blood cells to carry oxygen. Folic acid is essential for DNA synthesis, cell division, and red blood cell formation. Zinc supports numerous enzymatic reactions, protein formation, and immune function.

Alternate Names

• No widely recognized alternate names exist for this specific combination, but it may be referred to by the individual components: ferrous ascorbate, folic acid, and zinc sulfate/zinc sulfate monohydrate/zinc.

• Brand names: Many brand names exist depending on the manufacturer (e.g., Feroway, Zif-A, Lupired XT, Xoom, Abfer XT).

How It Works

• Pharmacodynamics: Iron from ferrous ascorbate is absorbed in the duodenum and proximal jejunum. Ascorbate enhances iron absorption. Iron is incorporated into hemoglobin, increasing oxygen-carrying capacity. Folic acid is converted to its active form, tetrahydrofolic acid, participating in DNA synthesis and red blood cell maturation. Zinc acts as a cofactor for various enzymes involved in cell growth, immune function, and protein synthesis.

• Pharmacokinetics: Ferrous ascorbate is absorbed in the gut, with ascorbate improving its bioavailability. Iron is transported by transferrin and stored as ferritin. Excess iron can accumulate and cause toxicity. Folic acid is absorbed in the small intestine and metabolized in the liver. Zinc is absorbed in the small intestine, transported by albumin, and stored in various tissues. Elimination pathways are primarily renal and fecal for all three components.

• Mode of action: Iron binds to protoporphyrin IX to form heme, the oxygen-carrying component of hemoglobin. Folic acid is converted to tetrahydrofolic acid, a cofactor for enzymes involved in DNA and amino acid synthesis. Zinc is a cofactor for many enzymes involved in various cellular processes. No direct receptor binding, specific enzyme inhibition, or neurotransmitter modulation is associated with this combination’s primary mechanism. Elimination primarily occurs through renal and fecal routes.

Dosage

Standard Dosage

Adults: One tablet daily. In severe cases, two tablets daily may be prescribed.

Children: Dosage is determined by the physician based on the child’s age, weight, and the severity of the deficiency. Safety and effectiveness in children have not been fully established in all cases.

Special Cases: Dosage adjustments are crucial in patients with renal or hepatic impairment, as dosage reduction may be necessary.

Clinical Use Cases

Dosing in clinical scenarios such as intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations is determined by the patient’s specific needs and underlying conditions. Iron, folic acid, or zinc supplementation might be individually adjusted according to clinical protocols. This combined formulation might not be suitable in all clinical situations.

Dosage Adjustments

Dose modification should be considered for patients with renal/hepatic dysfunction, based on their individual clearance rates and metabolic capacity.

Side Effects

Common Side Effects

• Nausea, constipation, diarrhea, stomach upset, dark stools.

Rare but Serious Side Effects

• Allergic reactions (hives, swelling, difficulty breathing). Liver damage (jaundice, abdominal pain). Iron overload.

Long-Term Effects

• Iron overload with chronic excessive intake.

Contraindications

• Hypersensitivity to any of the components. Hemochromatosis, hemosiderosis, or other iron overload conditions. Anemias not caused by iron deficiency (e.g., hemolytic anemia). Peptic ulcer disease, regional enteritis. Certain genetic disorders affecting folate metabolism. Zinc toxicity or hypersensitivity.

Drug Interactions

• Antacids, antibiotics (tetracyclines, quinolones), anticonvulsants, anti-cancer drugs, levodopa, thyroid medications, certain HIV medications, aspirin, sulfasalazine. Dairy products, tea, and coffee can reduce iron absorption. Alcohol may interfere with absorption.

Pregnancy and Breastfeeding

• Generally considered safe during pregnancy and breastfeeding, but physician consultation is necessary to determine appropriate dosage. Caution is advised in the first trimester of pregnancy unless iron deficiency is evident. Monitor iron and hemoglobin levels regularly.

Drug Profile Summary

• Mechanism of Action: Replenishes iron, folate, and zinc, essential for red blood cell production, DNA synthesis, and various metabolic processes.
