Usage
This combination medication is prescribed for preventing and treating vitamin B deficiencies, especially when dietary intake is insufficient, malabsorption occurs, or metabolic demands increase. Lysine is included to support protein synthesis, tissue repair, and growth. D-Panthenol aids wound healing and metabolic processes.
Pharmacological Classification: Vitamin Supplement, Nutritional Supplement
Mechanism of Action: This combination replenishes essential B vitamins (B1, B2, B3, B5, B6, and B12), acting as crucial coenzymes in various metabolic pathways, including energy production, DNA synthesis, and nerve function. Lysine contributes to protein synthesis and collagen formation. D-panthenol converts to pantothenic acid (vitamin B5), vital for fatty acid metabolism and maintaining healthy skin.
Alternate Names
Vitamin B Complex with Lysine; B Complex + Lysine + Panthenol; Multivitamin with Lysine.
Some brand names include Genoplex-L Syrup and Genoplex-L Syrup Sugar Free.
How It Works
Pharmacodynamics: B vitamins are essential coenzymes for numerous metabolic processes. Thiamine (B1) is crucial for carbohydrate metabolism. Riboflavin (B2) is involved in energy production and cellular function. Niacinamide (B3) plays a role in DNA repair and cell signaling. Pyridoxine (B6) contributes to neurotransmitter synthesis. Cyanocobalamin (B12) is essential for red blood cell formation and nerve function. D-Panthenol, a provitamin of B5, is involved in fatty acid synthesis and metabolism. Lysine is crucial for protein synthesis and various metabolic functions.
Pharmacokinetics:
- Absorption: Most B vitamins are absorbed in the small intestine.
- Metabolism: B vitamins undergo various metabolic transformations in the liver.
- Elimination: Primarily renal excretion.
Mode of Action: The components act as coenzymes or substrates in various metabolic pathways, facilitating essential biochemical reactions.
Receptor Binding, Enzyme Inhibition, or Neurotransmitter Modulation: While the components don’t directly bind to receptors, some, like B6, play a role in neurotransmitter synthesis.
Elimination Pathways: Primarily renal excretion.
Dosage
Dosing depends on the specific formulation and the patient’s individual needs. Always follow the manufacturer’s instructions for the prescribed product.
Standard Dosage
Adults:
Oral dosages vary widely depending on the formulation. One tablet or capsule daily is common, or as directed by a physician. Liquid formulations are administered in milliliters. Intramuscular injections are usually reserved for severe deficiencies.
Children:
Dosages are generally weight-or age-based and require careful calculation to prevent excessive vitamin intake.
Special Cases:
- Elderly Patients: Dose adjustments may be needed due to age-related changes in metabolism and organ function.
- Patients with Renal Impairment: Dose reduction may be necessary.
- Patients with Hepatic Dysfunction: Caution is advised, though specific adjustments may not always be required.
- Patients with Comorbid Conditions: Dosage individualization is necessary, considering drug interactions and potential exacerbations of underlying conditions.
Clinical Use Cases
Dosages in clinical settings like intubation, surgical procedures, mechanical ventilation, ICU use, and emergencies would be guided by the patient’s specific needs and clinical status. There are no specific dosage guidelines for these scenarios as the formulation is primarily a vitamin supplement and not a treatment for acute medical conditions.
Dosage Adjustments
Modifications are based on renal/hepatic function, metabolic disorders, or genetic polymorphisms affecting drug metabolism.
Side Effects
Common Side Effects
Generally well-tolerated, although mild gastrointestinal upset may occur.
Rare but Serious Side Effects
Allergic reactions, although rare, can occur.
Long-Term Effects
Long-term use at appropriate doses is generally considered safe. However, excessive intake of certain B vitamins can have adverse effects.
Adverse Drug Reactions (ADR)
Any unusual or severe reactions should be promptly reported and investigated.
Contraindications
Hypersensitivity to any component.
Drug Interactions
Certain medications, including antibiotics and some anticonvulsants, may interact with specific vitamins in this combination. Consult drug interaction resources for detailed information. Alcohol, smoking, and grapefruit juice can affect absorption and metabolism.
Pregnancy and Breastfeeding
Generally safe during pregnancy and lactation when taken as directed. However, excessive intake of certain vitamins, like vitamin A (not present in this combination), should be avoided.
