Cyanocobalamin + Folic Acid + Nicotinamide + Vitamin C

Usage

This combination of vitamins and minerals is primarily prescribed for the prevention and treatment of nutritional deficiencies, particularly those involving vitamin B12 (cyanocobalamin), folic acid, niacinamide (a form of vitamin B3), and vitamin C. These deficiencies can arise from inadequate dietary intake, malabsorption issues, increased requirements (e.g., pregnancy), or certain medical conditions. It is classified as a nutritional supplement.

Alternate Names

While there isn’t a single, universally recognized alternate name for this specific combination, it can be referred to by various permutations of its constituents, such as “Multivitamin with B12, C, folate, and niacinamide.” Brand names vary depending on the manufacturer and region.

How It Works

Pharmacodynamics: Each component exerts specific actions:

• Cyanocobalamin: Essential for DNA synthesis, red blood cell formation, and neurological function. It converts to active forms (methylcobalamin and adenosylcobalamin) within the body. Methylcobalamin is crucial for the synthesis of methionine from homocysteine and the formation of myelin. Adenosylcobalamin plays a role in the metabolism of fatty acids and amino acids.
• Folic Acid: Essential for DNA and RNA synthesis, cell division, and red blood cell maturation. It converts to tetrahydrofolic acid, a cofactor in various metabolic reactions involving one-carbon transfers. Crucial during periods of rapid cell growth and division, such as pregnancy.
• Nicotinamide: A precursor to nicotinamide adenine dinucleotide (NAD) and nicotinamide adenine dinucleotide phosphate (NADP), crucial coenzymes for cellular energy metabolism, DNA repair, and cell signaling.
• Vitamin C (Ascorbic Acid): Acts as an antioxidant, protecting cells from free radical damage. It also supports collagen synthesis, immune function, iron absorption, and the production of certain neurotransmitters.

Pharmacokinetics:

• Absorption: All components are generally well-absorbed orally, although the absorption of iron and vitamin B12 can be affected by certain dietary factors and medical conditions. Vitamin C enhances iron absorption.
• Metabolism: Folic acid is metabolized in the liver to its active form, tetrahydrofolic acid. Nicotinamide is metabolized to NAD and NADP. Vitamin B12 is transported and stored in the liver.
• Elimination: Excess amounts of these vitamins are typically eliminated in the urine.

Dosage

Dosage varies depending on the specific formulation and the individual patient’s needs.

Standard Dosage

Adults: A healthcare professional should determine the appropriate dose based on individual requirements.

Children: Dosage should be determined by a pediatrician based on age, weight, and clinical condition.

Special Cases:

• Elderly Patients: Dosage adjustments may be needed based on renal function and overall health.
• Patients with Renal Impairment: Dosage may need to be reduced, particularly for vitamin C and niacinamide.
• Patients with Hepatic Dysfunction: Caution is advised, especially with high doses of niacinamide.
• Patients with Comorbid Conditions: Consider interactions with other medications and underlying medical conditions.

Clinical Use Cases

This combination is typically not used in specific clinical settings like intubation, surgical procedures, mechanical ventilation, or emergency situations. Its primary role is in addressing nutritional deficiencies.
