Usage
This combination medication is primarily prescribed for the treatment and prevention of nutritional deficiencies, particularly those related to calcium, vitamin D, vitamin B12, folate, and omega-3 fatty acids. It may also be used to support bone health, nerve function, and cardiovascular health. This drug isn’t classified under a single pharmacological category, as it’s a combination of vitamins, minerals, and fatty acids, each having a distinct pharmacological action. Therefore, it’s best described as a nutritional supplement. The individual components have various mechanisms: calcitriol regulates calcium and phosphorus metabolism, methylcobalamin is involved in nerve cell maintenance and red blood cell production, folic acid is essential for cell growth and development, and docosahexaenoic acid and eicosapentaenoic acid are omega-3 fatty acids with anti-inflammatory and cardiovascular benefits.
Alternate Names
There is no internationally recognized non-proprietary name for this specific combination. Brand names vary depending on the manufacturer and region. Some examples include Caldikind Plus, Eucalmin, Steon, and Tobalt-Max. Different manufacturers may use slightly different formulations or dosages of the components.
How It Works
Pharmacodynamics:
- Calcitriol: The active form of vitamin D, promotes calcium absorption in the gut and regulates calcium and phosphorus levels in the body, essential for bone health.
- Calcium: A crucial mineral for bone formation, nerve function, muscle contraction, and blood clotting.
- Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA): Omega-3 fatty acids that have anti-inflammatory, antiplatelet, and triglyceride-lowering effects, contributing to cardiovascular health and brain function.
- Folic Acid: Essential for DNA synthesis, red blood cell formation, and neural development.
- Methylcobalamin: A form of vitamin B12, crucial for nerve function, red blood cell production, and DNA synthesis.
Pharmacokinetics:
- Absorption: Calcitriol is absorbed in the small intestine. Calcium absorption depends on various factors, including vitamin D levels. DHA, EPA, folic acid, and methylcobalamin are also absorbed in the gastrointestinal tract.
- Metabolism: Calcitriol is metabolized in the liver and kidneys. Methylcobalamin is converted to its active forms within the body. DHA and EPA are metabolized like other fatty acids.
- Elimination: Calcitriol is primarily excreted in bile. Calcium is excreted via urine and feces. DHA and EPA are eliminated through various routes, including bile and urine. Folic acid and methylcobalamin are primarily excreted in urine.
Mode of Action:
- Calcitriol: Binds to vitamin D receptors, influencing gene expression related to calcium and phosphorus transport.
- DHA and EPA: Incorporated into cell membranes, influencing cell function and competing with arachidonic acid in inflammatory pathways.
- Methylcobalamin: Acts as a coenzyme in various metabolic reactions.
- Folic acid: Involved in the synthesis of purines and pyrimidines, crucial for DNA and RNA synthesis.
Dosage
Standard Dosage
Adults:
The dosage depends on the specific product formulation and individual patient needs. Typically, one capsule or tablet daily is recommended, but this can vary widely based on the specific product. Consultation with a healthcare provider is essential for determining the appropriate dosage.
Children:
Dosage in children should be determined by a pediatrician and is based on age, weight, and specific nutritional needs.
Special Cases:
- Elderly Patients: Dosage adjustments may be required based on renal function and other health conditions.
- Patients with Renal Impairment: Careful dose adjustments are necessary due to calcitriol’s impact on calcium and phosphorus balance. Close monitoring of serum calcium and phosphorus levels is critical.
- Patients with Hepatic Dysfunction: Generally, no major adjustments are needed, but monitoring is advised.
- Patients with Comorbid Conditions: Patients with hypercalcemia, hyperparathyroidism, or kidney stones require specific dosage modifications.
Clinical Use Cases
This combination is not typically used in acute clinical settings like intubation, surgical procedures, mechanical ventilation, or intensive care unit (ICU) use. Individual components might be used separately in such situations.
Dosage Adjustments
Dose adjustments are determined by patient-specific factors, such as renal or hepatic function, metabolic disorders, and potential drug interactions. Regular monitoring of serum calcium, phosphorus, and vitamin D levels is crucial.
