Cyanocobalamin + Docosahexanoic acid + Folic Acid

Usage

This combination is prescribed for nutritional deficiencies, particularly during pregnancy, and to support overall health. It helps prevent neural tube defects in developing fetuses and supports brain development. The pharmacological classifications are vitamins (folic acid, cyanocobalamin) and an essential fatty acid (docosahexaenoic acid).

The mechanism of action involves:

• Folic acid: Essential for DNA and RNA synthesis, cell division, and red blood cell formation.
• Cyanocobalamin (Vitamin B12): Crucial for nerve function, red blood cell formation, and DNA synthesis.
• Docosahexaenoic acid (DHA): Important for brain and eye development, cognitive function, and cardiovascular health.

Alternate Names

No widely recognized alternate names exist for this specific combination. However, components are known as:

• Cyanocobalamin: Vitamin B12
• Docosahexaenoic Acid: DHA
• Folic Acid: Folate, Vitamin B9

Brand names vary depending on the manufacturer and region.

How It Works

Pharmacodynamics:

• Folic acid is converted into tetrahydrofolic acid, a coenzyme for various metabolic processes.
• Cyanocobalamin acts as a coenzyme for methionine synthase and methylmalonyl-CoA mutase, influencing DNA synthesis and nerve function.
• DHA integrates into cell membranes, particularly in the brain and eyes, supporting their structure and function. It also exhibits anti-inflammatory properties.

Pharmacokinetics:

• Folic acid: Absorbed in the small intestine, metabolized in the liver, and excreted renally.
• Cyanocobalamin: Requires intrinsic factor for absorption in the ileum. Stored in the liver and excreted renally.
• DHA: Absorbed in the small intestine, incorporated into cell membranes, and metabolized like other fatty acids.

Mode of Action:

• Folic acid facilitates single-carbon transfer reactions, crucial for DNA and amino acid synthesis.
• Cyanocobalamin participates in myelin formation and nerve conduction.
• DHA influences cell membrane fluidity, neurotransmission, and signal transduction pathways.

Elimination: Primarily renal excretion for folic acid and cyanocobalamin. DHA is metabolized and eliminated like other fatty acids.

Dosage

Dosage is determined based on individual patient needs and the specific formulation. General guidelines are:

Standard Dosage

Adults: A common dosage includes 400 mcg of folic acid and 200 mg of DHA. The dose of Vitamin B12 (Cyanocobalamin) depends on the individual’s needs.

Children: Dosage needs to be determined by a pediatrician based on age and medical condition.

Special Cases: Dosage adjustments may be necessary for:

• Elderly Patients: Based on renal function and overall health.
• Patients with Renal Impairment: Dose reduction may be needed.
• Patients with Hepatic Dysfunction: Careful monitoring is required.
• Patients with Comorbid Conditions: Dosage adjustments might be required based on other medical conditions.

Clinical Use Cases

This combination is not typically used in acute clinical settings like intubation, surgical procedures, mechanical ventilation, ICU, or emergency situations. It is primarily for nutritional supplementation.

Dosage Adjustments

Dosage adjustments should be made based on individual patient factors such as renal or hepatic dysfunction.

Side Effects

Common Side Effects

Nausea, vomiting, diarrhea, loss of appetite, headache, fatigue, bloating, flatulence, fishy burps, and bitter taste. These are usually mild and self-limiting.

Rare but Serious Side Effects

Allergic reactions (rash, itching, swelling), and masking of Vitamin B12 deficiency.

Long-Term Effects

No significant long-term effects are typically observed with this combination when taken as directed. However, excessive intake of any component can have adverse effects.

Adverse Drug Reactions (ADR)

Severe allergic reactions are rare but require immediate medical attention.

Contraindications

Hypersensitivity to any of the components. Certain hereditary problems related to folic acid metabolism. Untreated pernicious anemia. Hemochromatosis, iron storage disease, or chronic hemolytic anemia for iron supplementation. Sensitivity to cobalt or cyanocobalamin.

Drug Interactions

Certain antibiotics, anticonvulsants, medications for diabetes, and blood thinners. Alcohol can reduce folic acid absorption. Antacids may interfere with absorption.

Pregnancy and Breastfeeding

Generally considered safe during pregnancy and breastfeeding. Essential for fetal development. However, consult a doctor for individualized advice.
