Usage
This combination is primarily prescribed as a nutritional supplement to address deficiencies in these specific vitamins and support overall health, particularly nerve function, skin health, and energy metabolism. It’s also used to manage peripheral neuropathy (nerve pain in the extremities), megaloblastic and other types of anemia, and promote wound healing.
- Pharmacological Classification: Nutritional supplement, vitamin combination.
- Mechanism of Action: This combination works by replenishing depleted levels of these essential nutrients, enabling them to carry out their respective roles in cellular function, nerve conduction, energy production, and tissue repair.
Alternate Names
There isn’t a universally recognized alternate name for this specific combination. However, it can be referred to by the individual components: D-Panthenol (Provitamin B5), Methylcobalamin (Vitamin B12), Niacinamide (Vitamin B3), and Vitamin B6 (Pyridoxine).
- Brand Names: Brand names vary regionally and internationally; examples include (but are not limited to) “MECLAB-PLUS”, “MBN Plus,” and various other names depending on the specific manufacturer and formulation. Always refer to the product packaging for accurate brand and composition information. Numerous generic versions are also available.
How It Works
-
Pharmacodynamics:
- D-Panthenol: Converted to pantothenic acid, a component of coenzyme A, vital for energy metabolism and fatty acid synthesis. Supports cell growth and repair, maintains healthy skin and mucous membranes.
- Methylcobalamin: Active form of Vitamin B12, crucial for nerve function, DNA synthesis, and red blood cell formation. Helps regulate homocysteine levels, impacting cardiovascular health.
- Niacinamide: Improves cellular energy metabolism, has anti-inflammatory and antioxidant properties, beneficial for skin health.
- Vitamin B6 (Pyridoxine): Essential for protein and amino acid metabolism, neurotransmitter synthesis, red blood cell formation, and cognitive function.
-
Pharmacokinetics:
- Absorption: Generally well-absorbed orally, although absorption of vitamin B12 can be impaired in individuals with pernicious anemia or other malabsorption syndromes. Injectable forms bypass the digestive tract, ensuring systemic delivery.
- Metabolism: Each component is metabolized differently; for example, D-Panthenol is converted to pantothenic acid, vitamin B6 to pyridoxal 5’-phosphate (PLP), and niacinamide undergoes various metabolic pathways.
- Elimination: Primarily renal excretion for all components, although some metabolites may be eliminated via bile or other routes.
-
Mode of Action (Cellular/Molecular Level): The combination acts by providing essential cofactors for various enzymatic reactions involved in energy metabolism, neurotransmission, DNA synthesis, and cellular repair.
-
Receptor Binding, Enzyme Inhibition, Neurotransmitter Modulation: The components exert their effects by participating in enzymatic processes rather than direct receptor binding or neurotransmitter modulation, except for vitamin B6’s role in neurotransmitter synthesis.
-
Elimination Pathways: Predominantly renal excretion, with variations depending on specific metabolites.
Dosage
Dosage should be individualized based on the patient’s specific needs and medical condition. Always consult with a healthcare professional for appropriate dosing guidance. The following is for informational purposes only and does not substitute professional medical advice.
Standard Dosage
Children: Pediatric dosing should be carefully determined by a pediatrician or healthcare professional based on age, weight, and health status.
Special Cases:

- Liver damage (high doses of niacinamide)
Long-Term Effects
Limited data on long-term effects; however, prolonged high doses of individual components may pose risks (e.g., neuropathy with vitamin B6).
Adverse Drug Reactions (ADR)
Clinically significant ADRs are rare but require prompt medical attention if they occur (e.g., severe allergic reactions, signs of liver dysfunction).
Contraindications
- Hypersensitivity to any component of the combination.
- Certain specific conditions (consult with a healthcare professional).
Drug Interactions
-
May interact with various medications including, but not limited to:
- Levodopa

- H2 receptor antagonists (e.g., cimetidine)
- Anticonvulsants (e.g., phenytoin, phenobarbital)
- Medications for diabetes or high blood pressure
-
Alcohol should be avoided or limited as it may interfere with nutrient absorption.
