Usage
This combination medication is primarily prescribed for preventing and treating nutritional deficiencies, especially deficiencies in calcium, vitamin D, folate, vitamin B12, and vitamin B6. It also aids in improving calcium absorption and promoting bone health, particularly in individuals at risk of osteoporosis.
Pharmacological Classification: This combination product falls into multiple categories:
- Calcium Supplement: Calcium carbonate is the primary calcium source.
- Vitamin Supplement: Vitamin D3, L-methyl folate, methylcobalamin, and pyridoxal-5-phosphate are vitamin supplements.
- Mineral Supplement: Light magnesium oxide supplements dietary magnesium.
Mechanism of Action: Each component contributes to the overall therapeutic effect:
- Calcium Carbonate: Supplies calcium essential for bone mineralization, nerve function, and muscle contraction.
- Vitamin D3: Facilitates calcium absorption from the gastrointestinal tract and regulates calcium and phosphorus homeostasis.
- L-Methyl Folate: The biologically active form of folic acid is crucial for DNA synthesis, red blood cell formation, and neural tube development.
- Methylcobalamin: The active form of vitamin B12, plays a vital role in red blood cell production, nerve function, and DNA synthesis.
- Pyridoxal-5-phosphate: The active form of vitamin B6, is involved in red blood cell formation and various metabolic processes.
- Light Magnesium Oxide: Contributes to bone health, nerve function, and muscle function.
Alternate Names
- Calcium Carbonate + Vitamin D3 + L-Methylfolate + Methylcobalamin + Pyridoxal-5-Phosphate + Magnesium Oxide
- Calcium + Vitamin D3 + Folate + Vitamin B12 + Vitamin B6 + Magnesium Supplement
Brand names may vary depending on the manufacturer and region. One example is Kalzimin Plus Softgel Capsule.
How It Works
Pharmacodynamics: The combined effects of the components contribute to bone health, nerve and muscle function, red blood cell formation, and overall metabolic processes.
Pharmacokinetics:
- Absorption: Calcium carbonate absorption is enhanced by vitamin D3. The other components are generally well-absorbed.
- Metabolism: L-methyl folate, methylcobalamin, and pyridoxal-5-phosphate are active forms of their respective vitamins, requiring minimal metabolic conversion.
- Elimination: Excess calcium and magnesium are primarily excreted renally. Vitamins are metabolized and excreted through various pathways, including renal and hepatic routes.
Mode of Action: Each component acts at a cellular and molecular level. Vitamin D3 modulates gene expression related to calcium transport. L-methyl folate, methylcobalamin, and pyridoxal-5-phosphate participate as cofactors in enzymatic reactions related to DNA synthesis, red blood cell formation, and various metabolic pathways.
Dosage
Dosage should be individualized based on patient needs, clinical response, and the specific formulation of the medication.
Standard Dosage
Adults: One tablet or capsule daily or as directed by a physician. The exact dosage of each component will vary based on the specific product. It’s recommended to follow the manufacturer’s instructions or consult with a healthcare professional.
Children: Dosage should be determined by a pediatrician based on the child’s age, weight, and the specific deficiency being addressed.
Special Cases:
- Elderly Patients: Dosage adjustments may be necessary depending on renal function and other comorbidities.
- Patients with Renal Impairment: Dose reduction might be necessary to avoid calcium and magnesium accumulation.
- Patients with Hepatic Dysfunction: Careful monitoring is recommended, and dose adjustments may be considered depending on the severity of dysfunction.
- Patients with Comorbid Conditions: Individualized adjustments may be needed based on the specific comorbid condition.
Clinical Use Cases
The combination isn’t specifically indicated for acute medical settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations. Its primary use is for nutritional supplementation.
Dosage Adjustments
Modifications should be based on renal or hepatic function, metabolic disorders, or genetic polymorphisms affecting drug metabolism.
Side Effects
Common Side Effects: Constipation, nausea, and mild gastrointestinal discomfort.
Rare but Serious Side Effects: Hypercalcemia (elevated blood calcium levels), particularly with excessive doses.
Long-Term Effects: Potential for kidney stones with prolonged high-dose calcium intake.
Contraindications
- Hypercalcemia
- Hypervitaminosis D
- Known hypersensitivity to any component of the formulation
Drug Interactions
- Antacids containing aluminum or magnesium may interfere with calcium absorption.
- Certain antibiotics (e.g., tetracyclines, quinolones) may bind with calcium and reduce their absorption.
- Levothyroxine absorption can be affected by calcium supplements.
Pregnancy and Breastfeeding
This combination can generally be used during pregnancy and breastfeeding if clinically indicated. However, it’s crucial to ensure the dosage is appropriate to avoid exceeding recommended daily allowances for vitamins and minerals.
Drug Profile Summary

- Specific Populations: Monitor patients with renal impairment for potential electrolyte imbalances.
- Lifestyle Considerations: Adequate hydration is recommended to reduce the risk of constipation and kidney stones.
FAQs (Frequently Asked Questions)
Q1: What is the recommended dosage for Calcium Carbonate + L-Methyl Folate + Light Magnesium Oxide + Methylcobalamin + Pyridoxal-5-phosphate + Vitamin D3?
A: The recommended dosage varies depending on individual patient needs. Generally, one tablet or capsule daily is recommended for adults, but this should be adjusted based on specific product formulation and clinical response. Pediatric dosages should be determined by a pediatrician.
Q2: Can this combination be used in patients with osteoporosis?
A: Yes, it can be used as a supplement to support bone health in patients with osteoporosis, but it is not a standalone treatment. Other osteoporosis medications might be necessary.
Q3: What are the common side effects patients should be aware of?
A: Common side effects include constipation, nausea, and mild gastrointestinal discomfort. Advise patients to increase fluid intake and dietary fiber to mitigate constipation.
Q4: Are there any drug interactions I should be aware of?
A: Yes, this combination can interact with medications such as antacids, certain antibiotics (tetracyclines, quinolones), and levothyroxine. Monitor patients carefully for potential interactions.
Q5: Can pregnant or breastfeeding women take this combination?
A: Generally, it’s considered safe during pregnancy and breastfeeding, but it’s crucial to ensure the dosage is appropriate and does not exceed the recommended daily intake of vitamins and minerals. Consult with a healthcare professional for guidance.
Q6: How should patients with renal impairment be managed?
A: Patients with renal impairment require careful monitoring, and dosage adjustments may be necessary due to impaired calcium and magnesium excretion. Monitor serum calcium, magnesium, and creatinine levels.
Q7: What is the role of L-methyl folate in this combination?
A: L-methyl folate, the active form of folic acid, plays an essential role in DNA synthesis, red blood cell formation, and neural tube development, making it especially important during pregnancy.
A: Methylcobalamin is the active form of B12 and is more readily utilized by the body than cyanocobalamin. This combination uses the more bioavailable methylcobalamin.
Q9: What should I monitor in patients taking this medication long-term?
A: Monitor serum calcium, magnesium, and vitamin D levels regularly. Also, be mindful of the potential for kidney stones with prolonged high-dose calcium intake. Encourage adequate hydration.
