Usage
This combination medication is prescribed to address deficiencies in calcium, folic acid, vitamin D3, methylcobalamin (vitamin B12), and zinc. It’s commonly used to prevent and treat conditions related to these deficiencies, such as osteoporosis, osteomalacia, rickets, and megaloblastic anemia (specifically related to folic acid and B12 deficiency). It also aids in preventing neural tube defects during pregnancy and managing hypocalcemia. It supports nerve function, DNA synthesis, and red blood cell maturation. This combination falls under the pharmacological classification of nutritional supplements and vitamin/mineral combinations.
The mechanism of action involves each component contributing its specific function: calcium for bone health and various physiological processes, vitamin D3 for calcium absorption, folic acid and methylcobalamin for DNA synthesis and red blood cell formation, and zinc for immune function and cell growth.
Alternate Names
There isn’t one single international nonproprietary name (INN) for this specific combination. Each component has its own INN (e.g., calcium citrate, folic acid, methylcobalamin, cholecalciferol for Vitamin D3, zinc sulfate monohydrate). The combination itself is usually referred to by the names of its components. Brand names vary depending on the manufacturer and region.
How It Works
Pharmacodynamics: Calcium is essential for bone mineralization, muscle contraction, nerve transmission, and blood clotting. Vitamin D3 promotes calcium absorption in the gut. Folic acid and methylcobalamin are crucial for DNA synthesis, cell division, and red blood cell maturation. Zinc is a cofactor for numerous enzymes involved in cell growth, immune function, and protein synthesis.
Pharmacokinetics: Calcium citrate is absorbed in the intestines, facilitated by vitamin D3. Folic acid is absorbed primarily in the jejunum. Methylcobalamin requires intrinsic factor for absorption in the ileum. Vitamin D3 is absorbed in the small intestine and undergoes hepatic and renal metabolism to its active form, calcitriol. Zinc is absorbed in the small intestine. Elimination pathways vary: calcium is excreted primarily renally, folic acid through renal and hepatic routes, methylcobalamin primarily through the bile, vitamin D3 is metabolized and excreted in bile and urine and zinc is eliminated primarily through feces.
Dosage
Dosage is highly patient-specific and should be determined by a physician.
Standard Dosage
Adults: Dosing depends on individual deficiencies and the condition being treated. Typical daily intake ranges are: Calcium (1000-1300 mg), Vitamin D3 (600-800 IU), Folic acid (400-800 mcg), Methylcobalamin (1000-2500 mcg), Zinc (15-30 mg).
Children: Pediatric dosing should be determined by a pediatrician based on age, weight, and specific needs.
Special Cases:
- Elderly Patients: May require adjustments due to age-related changes in absorption and metabolism.
- Patients with Renal Impairment: Dose reductions may be necessary, especially for calcium and vitamin D3.
- Patients with Hepatic Dysfunction: Adjustments may be needed for certain components, particularly folic acid and methylcobalamin.
- Patients with Comorbid Conditions: Careful consideration is required for patients with conditions like hypercalcemia, hypercalciuria, or certain types of anemia.
Clinical Use Cases
Dosages in these settings should be individualized and guided by clinical assessment and patient response.
