Calcium Pantothenate + Methylcobalamin + Niacinamide + Vitamin C + Vitamin E

Usage

This combination of vitamins is prescribed for the prevention and treatment of vitamin deficiencies, especially those of the B complex, vitamin C, and vitamin E. It supports overall health and well-being. It may be prescribed for conditions like:

• B-Complex Deficiencies: Conditions such as beriberi (thiamine deficiency), ariboflavinosis (riboflavin deficiency), pellagra (niacin deficiency), and peripheral neuropathy (vitamin B12 deficiency).
• Vitamin C Deficiency: Scurvy
• Vitamin E Deficiency: Ataxia, peripheral neuropathy
• Other Conditions: Sometimes used as supportive therapy for conditions like diabetes, cardiovascular disease, and during pregnancy.

Pharmacological Classification: Vitamin Supplement, Dietary Supplement

Mechanism of Action: This combination provides essential vitamins that play crucial roles in various metabolic processes.

Alternate Names

• Vitamin B Complex with Vitamin C and E
• Multivitamin with B complex, C, and E
• B vitamins with Ascorbic Acid and Tocopherol

How It Works

Pharmacodynamics:

• Calcium Pantothenate: A precursor to coenzyme A, essential for fatty acid synthesis and metabolism, carbohydrate metabolism, and the synthesis of cholesterol and steroid hormones.
• Methylcobalamin: A coenzyme for methionine synthase, essential for DNA synthesis, nerve cell function, and red blood cell formation.
• Niacinamide: A precursor to NAD and NADP, crucial for energy metabolism, DNA repair, and cell signaling.
• Vitamin C (Ascorbic Acid): An antioxidant, necessary for collagen synthesis, immune function, and iron absorption.
• Vitamin E (Tocopherol): An antioxidant that protects cell membranes from damage.

Pharmacokinetics:

• Absorption: These vitamins are generally well-absorbed orally.
• Metabolism: Each vitamin undergoes specific metabolic pathways. Vitamin C is primarily metabolized in the liver. Vitamin E is partially metabolized in the liver. B vitamins are metabolized in various tissues.
• Elimination: Primarily renal excretion, but some biliary excretion may occur.

Mode of Action: Each vitamin acts as a cofactor or coenzyme in various enzymatic reactions essential for cellular function.

Dosage

Standard Dosage

Adults: Dosage varies depending on the formulation and the indication. A common dosage is one tablet or capsule daily, as determined by a healthcare professional.

Children: Pediatric dosing is determined by a physician based on age, weight, and individual needs.

Special Cases:

• Elderly Patients: Dosage may require adjustment.
• Patients with Renal Impairment: Dosage adjustment may be needed for some vitamins.
• Patients with Hepatic Dysfunction: Generally, no specific adjustments are necessary.
• Patients with Comorbid Conditions: Individualized dosing based on the comorbid condition is recommended.

Clinical Use Cases

Dosage is individualized based on patient needs and determined by the attending physician for the following:

• Intubation
• Surgical Procedures
• Mechanical Ventilation
• Intensive Care Unit (ICU) Use
• Emergency Situations

Dosage Adjustments: Dose modification may be necessary for renal/hepatic dysfunction, metabolic disorders, or genetic polymorphisms affecting drug metabolism.

Side Effects

Common Side Effects:

• Mild gastrointestinal upset (nausea, diarrhea, abdominal cramps)
• Headache
• Fatigue
• Flushing

Rare but Serious Side Effects: Allergic reactions (rash, itching, swelling, dizziness, difficulty breathing)

Adverse Drug Reactions (ADR): Rarely, hypersensitivity reactions can occur.

Contraindications

• Known hypersensitivity to any of the ingredients.
• Certain conditions such as hemochromatosis, hemosiderosis, or hemolytic anemia.
• Pernicious anemia (for high doses of folic acid)
• Vitamin K deficiency (for high doses of vitamin E).
• Patients on anticoagulants (vitamin E interactions)

Drug Interactions

• Chemotherapy medications (e.g., doxorubicin, cyclophosphamide)
• Estrogens (e.g., conjugated estradiol)
• Protease inhibitors (e.g., ritonavir)
• Statins (e.g., atorvastatin)
• Levodopa
• Anticonvulsants
• Antacids
• Proton pump inhibitors
• Certain antibiotics

Pregnancy and Breastfeeding

Generally considered safe during pregnancy and breastfeeding when used as directed. However, consultation with a doctor is always recommended. Adequate folic acid is crucial during pregnancy to prevent neural tube defects.
