D-Panthenol + Niacinamide + Silymarin + Vitamin B12 + Vitamin B2 + Vitamin B6

Usage

This combination of vitamins and silymarin is primarily prescribed for the prevention and treatment of deficiencies in these specific nutrients, particularly due to poor diet, certain illnesses, alcoholism, or during pregnancy. It supports overall health with a focus on liver health, nerve function, skin health, and energy metabolism. It can be beneficial in conditions such as:

• Peripheral neuropathy
• Vitamin B12 deficiency anemia
• Wernicke-Korsakoff syndrome
• Pellagra
• Ariboflavinosis
• Hepatic diseases

Pharmacological Classification: This combination belongs to the class of vitamins and hepatoprotective agents due to the inclusion of silymarin. It does not neatly fit into a single drug category like antibiotic or analgesic. It is primarily considered a nutritional supplement.

Mechanism of Action: This formulation works through the synergistic action of its components:

• D-Panthenol (Provitamin B5): Converted to pantothenic acid, a component of coenzyme A, essential for energy metabolism and fatty acid synthesis.
• Niacinamide (Vitamin B3): Converted to NAD and NADP, vital coenzymes for energy metabolism and cellular function. Also possesses anti-inflammatory properties beneficial for skin health.
• Silymarin: A complex of flavonolignans with antioxidant and hepatoprotective properties. Stabilizes hepatocyte membranes, reduces lipid peroxidation, and stimulates liver regeneration.
• Vitamin B12 (Cyanocobalamin/Methylcobalamin): Crucial for nerve function, red blood cell formation, and DNA synthesis.
• Vitamin B2 (Riboflavin): A precursor to FMN and FAD, essential for energy production, cellular growth, and metabolism of fats, carbohydrates, and proteins.
• Vitamin B6 (Pyridoxine): Involved in neurotransmitter synthesis, red blood cell formation, and various metabolic processes.

Alternate Names

This combination doesn’t have one single international nonproprietary name (INN). It’s typically referred to by its component names. Some sources might use the terms “B-complex vitamins with silymarin” or “Liver support formula with B vitamins.” Numerous brand names exist depending on the manufacturer and specific formulation. Some examples as per my knowledge are Silirich, Hepatune 200, Cilimorin-B12 and Livoriv B Suspension.

How It Works

Pharmacodynamics: The effects of this combination are primarily driven by the individual actions of its components on various metabolic pathways and physiological processes as outlined in the mechanism of action.

Pharmacokinetics:

• Absorption: Absorption of individual components varies. B vitamins are generally well-absorbed orally. Silymarin has limited bioavailability but improves with some formulations.
• Metabolism: B vitamins are metabolized in the liver. Silymarin undergoes phase I and II metabolism.
• Elimination: B vitamins and silymarin metabolites are primarily excreted renally.

Mode of Action (Cellular/Molecular Level): The individual vitamins function as coenzymes in key enzymatic reactions within cells. Silymarin acts as an antioxidant, scavenging free radicals, inhibiting lipid peroxidation, and promoting protein synthesis in hepatocytes.

Receptor Binding/Enzyme Inhibition/Neurotransmitter Modulation:

• No specific receptor binding identified for silymarin.
• B vitamins participate as coenzymes in numerous enzyme-driven reactions, without directly acting as inhibitors themselves.
• Vitamin B6 is crucial for the synthesis of several neurotransmitters.

Dosage

Dosage recommendations vary based on the specific product formulation and the target indication. Consult product-specific information for precise guidance. General guidance, derived from available information, is as follows:

Standard Dosage

Adults: Oral administration is the most common route. Dosage depends on the specific product, with a common range for capsules being 1-2 capsules two to three times a day. Liquid formulations have varying concentrations, requiring adjustment as per product information.

Children: Consult a pediatrician. Specific pediatric formulations and dosage adjustments based on age or weight are crucial.

Special Cases:

• Elderly Patients: Dosage adjustments are typically not necessary unless renal or hepatic impairment exists.
• Patients with Renal Impairment: Careful dosage adjustments may be necessary based on the degree of impairment, especially for water-soluble vitamins. Monitor renal function closely.
• Patients with Hepatic Dysfunction: Caution advised, as some components are metabolized in the liver. Closely monitor liver function.
• Patients with Comorbid Conditions: Adjustments based on the specific comorbidity may be necessary.

Clinical Use Cases

Specific dosage guidelines for these clinical scenarios would depend on the patient’s overall condition, nutritional status, and the specific product being used. Consult with a clinical dietitian or pharmacist, particularly in intensive care settings.

Dosage Adjustments

Dose modifications are necessary for patients with renal or hepatic impairment. Consider specific product information for accurate adjustments.
