D-Panthenol + Methylcobalamin + Nicotinamide + Pyridoxine Hydrochloride

Usage

• This combination is prescribed for nutritional deficiencies, particularly those involving B vitamins. It’s also used to treat peripheral neuropathy (nerve damage), diabetic neuropathy, and certain types of anemia (like megaloblastic anemia). It may also be used to support overall health, improve nerve function, reduce inflammation, and promote healthy skin.
• Pharmacological classification: Nutritional supplement, vitamin combination.
• Mechanism of action: This combination works by providing the body with essential B vitamins. D-Panthenol (provitamin B5) converts to pantothenic acid, a component of coenzyme A crucial for energy metabolism. Methylcobalamin (vitamin B12) aids nerve function, red blood cell formation, and homocysteine regulation. Nicotinamide (vitamin B3) is vital for cell health, energy metabolism, and has anti-inflammatory properties. Pyridoxine hydrochloride (vitamin B6) is involved in protein and amino acid metabolism and neurotransmitter synthesis.

Alternate Names

• No widely recognized alternate names exist for this specific combination. It is commonly referred to by its component vitamins.
• Brand names: Mincoba, Meb-Plus, MECOGEN-PLUS, Anicobal Plus (Note: Brand names can vary regionally.)

How It Works

• Pharmacodynamics: Each vitamin in the combination exerts specific effects. D-panthenol supports cell growth and function, particularly affecting skin and mucous membranes. Methylcobalamin is crucial for nerve cell maintenance and function. Nicotinamide impacts cellular energy production and has anti-inflammatory effects. Pyridoxine hydrochloride is essential for various metabolic processes, particularly in nerve and red blood cell function.
• Pharmacokinetics:
  • Absorption: All components are well-absorbed following oral or parenteral administration.
  • Metabolism: D-Panthenol is readily converted to pantothenic acid. Methylcobalamin, nicotinamide, and pyridoxine hydrochloride undergo metabolic conversions to active forms.
  • Elimination: Primarily renal excretion for all components.
• Mode of action: These vitamins act as cofactors or precursors for essential enzymes involved in various metabolic pathways. Methylcobalamin, for example, is a cofactor for methionine synthase, an enzyme crucial for nerve function and homocysteine regulation. Nicotinamide forms NAD and NADP, which are key molecules in cellular energy production.
