Docosahexanoic Acid + Ferrous Ascorbate + Folic Acid + Methylcobalamin + Vitamin D3 + Zinc Sulphate Monohydrate

Usage

This combination of nutrients is prescribed to address deficiencies in iron, folic acid, zinc, vitamin B12, vitamin D3, and docosahexaenoic acid (DHA). It’s commonly used to treat and prevent nutritional anemias, especially during pregnancy and lactation. It’s also prescribed for general health maintenance, particularly when dietary intake of these nutrients is insufficient or when there’s increased demand, such as during periods of rapid growth or recovery from illness. This combination doesn’t fall neatly into a single pharmacological classification, but rather is a nutritional supplement. It addresses deficiencies by providing the necessary components for red blood cell formation, nerve function, bone health, and overall metabolic processes.

Alternate Names

This combination medication doesn’t have a single, universally recognized international nonproprietary name (INN). It’s generally referred to by the names of its constituent ingredients. Brand names vary depending on the manufacturer and region, and may or may not be available.

How It Works

Pharmacodynamics:

• Docosahexaenoic Acid (DHA): An omega-3 fatty acid crucial for brain development and function. It’s incorporated into cell membranes, influencing their fluidity and function.
• Ferrous Ascorbate: Provides iron, essential for hemoglobin synthesis. Ascorbate enhances iron absorption. Iron is a key component of hemoglobin, responsible for oxygen transport.
• Folic Acid: Essential for DNA synthesis, cell division, and red blood cell formation. It plays a crucial role in preventing neural tube defects during fetal development.
• Methylcobalamin: The active form of vitamin B12, vital for nerve function, DNA synthesis, and red blood cell maturation. It’s involved in myelin formation and maintenance.
• Vitamin D3: Regulates calcium and phosphorus absorption, crucial for bone health. It also plays a role in immune function and cell differentiation.
• Zinc Sulphate Monohydrate: Zinc is a cofactor for numerous enzymes involved in various metabolic processes, including DNA synthesis, protein synthesis, and immune function. It’s important for wound healing and cell growth.

Pharmacokinetics:

The individual components are absorbed, metabolized, and eliminated differently:

• DHA: Absorbed in the small intestine and incorporated into cell membranes.
• Ferrous Ascorbate: Iron is absorbed in the duodenum and jejunum, influenced by factors like the presence of ascorbate and the body’s iron stores.
• Folic Acid: Absorbed in the small intestine.
• Methylcobalamin: Absorbed in the ileum, requiring intrinsic factor for absorption. It’s stored in the liver.
• Vitamin D3: Absorbed in the small intestine and hydroxylated in the liver and kidneys to its active form.
• Zinc Sulphate Monohydrate: Absorbed in the small intestine.

Elimination pathways also vary. Iron is primarily excreted through shedding of intestinal cells, with minimal renal excretion. Folic acid and methylcobalamin are primarily excreted in urine. Vitamin D metabolites are excreted in bile and urine. Zinc is mainly excreted in feces.

Dosage

Dosage depends on individual patient needs and the severity of the deficiencies. A doctor should always determine the appropriate dosage.

Standard Dosage

Adults: Dosage will depend on the specific formulation and clinical needs. It’s best to follow medical advice regarding adult dosing.

Children: Pediatric dosing should be determined by a doctor and is typically based on age and weight.

Special Cases:

• Elderly Patients: May require adjusted doses due to age-related changes in absorption and metabolism.
• Patients with Renal Impairment: Dose adjustments may be necessary based on the degree of renal dysfunction.
• Patients with Hepatic Dysfunction: Dose adjustments may be required due to impaired metabolism.
• Patients with Comorbid Conditions: Underlying medical conditions should be considered when determining dosage.

Clinical Use Cases

The combination itself is not generally indicated for specific clinical scenarios like intubation, surgery, mechanical ventilation, or ICU use. However, individual components may be administered in these settings based on specific patient needs (e.g., intravenous iron supplementation in cases of severe anemia).

Dosage Adjustments

Dose adjustments are based on the specific deficiency being addressed, patient response, and any underlying health conditions or drug interactions.

Side Effects

Common Side Effects

• Nausea
• Constipation
• Dark stools
• Metallic taste in mouth

Rare but Serious Side Effects

• Allergic reactions (rash, itching, swelling)

Long-Term Effects

Long-term excessive intake of certain components (e.g., iron) can have adverse effects.

Adverse Drug Reactions (ADR)

ADRs are rare, but may include gastrointestinal upset or allergic reactions.

Contraindications

• Hypersensitivity to any component of the combination.
• Hemochromatosis (iron overload disorder).
• Certain anemias not caused by nutrient deficiencies.

Drug Interactions

Certain medications can interact with components of this combination. For example, antacids can reduce iron absorption, and certain antibiotics can interact with zinc.

Pregnancy and Breastfeeding

This combination is often prescribed during pregnancy and breastfeeding to address increased nutritional needs. However, it’s essential to consult a doctor for appropriate dosing and monitoring.
