Cadla (0.5µg) 20 Tablets

Alfacalcidol, the active ingredient in Alfacalcidol 0.5 mcg tablets, is a synthetic analog of vitamin D. Its mechanism of action involves mimicking the effects of naturally occurring vitamin D metabolites in the body. Alfacalcidol is rapidly converted in the liver to 1,25-dihydroxyvitamin D, which is the active form of vitamin D. This active metabolite binds to vitamin D receptors (VDR) present in various target tissues, primarily the intestine, kidneys, and bones. By activating the VDR, Alfacalcidol stimulates the absorption of calcium and phosphorus from the intestines, increases renal tubular reabsorption of calcium, and promotes bone mineralization. It enhances the efficiency of calcium absorption, leading to increased serum calcium levels. This process plays a crucial role in maintaining calcium homeostasis, promoting bone health, and supporting various physiological processes that require calcium and vitamin D.

Following are the precautions and warnings for Alfacalcidol 0.5mcg Tablet:

• Do not take this medication if you are allergic to alfacalcidol or any similar vitamin D derivatives.
• Regular monitoring of calcium levels in the blood and urine is essential during treatment.
• Patients with a history of kidney disease or impaired kidney function should exercise caution and consult a doctor, as dosage adjustments may be necessary.
• Alfacalcidol can cause an increase in calcium levels in the blood, which may lead to calcification in the kidneys and other organs. Regular monitoring is required.
• Avoid excessive use of calcium supplements or vitamin D-rich foods while on this medication.
• Elderly patients may be more susceptible to the effects of this medication; regular monitoring is recommended.
• This medication should be used with caution in pregnant and breastfeeding women under strict medical supervision.

Following are the drug interactions for Alfacalcidol 0.5mcg Tablet:

• Anticonvulsants like phenytoin and phenobarbital may decrease the effectiveness of Alfacalcidol.
• Thiazide diuretics can enhance the effects of Alfacalcidol, requiring dosage adjustments.
• Calcium-containing antacids can reduce the absorption of Alfacalcidol when taken together.
• Corticosteroids may increase calcium excretion, reducing Alfacalcidol's effectiveness.
• Digitalis glycosides may lead to cardiac arrhythmias when used with Alfacalcidol.
• Cisplatin may increase the risk of hypercalcemia when combined with Alfacalcidol.
• Antibiotics such as tetracyclines and quinolones can decrease the absorption of Alfacalcidol.

Following are the food interactions for Alfacalcidol 0.5mcg Tablet:

• Alfacalcidol absorption can be affected by high-fiber diets, as fiber can bind to the drug and reduce its absorption. Avoid excessive fiber intake shortly before or after taking the medication.
• Calcium-rich foods like milk, cheese, and yogurt can be beneficial when taking Alfacalcidol, as they help maintain calcium levels in the body. Consume these foods as part of a balanced diet.

Alfacalcidol is a vitamin D derivative that acts as a therapeutic agent for conditions like hypocalcemia and metabolic bone disease among individuals who have kidney failure. The laboratory tests required to accompany Alfacalcidol depend on the individual's medical situation and the condition that is being treated. In general, it is important to monitor vitamin D levels, calcium, and phosphate levels in the blood to ensure they are within the normal range. Given the nature of the medication and its potential impact on the kidneys, kidney function tests are often required, checking for example for BUN (blood urea nitrogen) and creatinine. It is also important to monitor for any potential adverse effects of the medication on kidney function. Other relevant tests may include parathyroid hormone levels and osteocalcin, as well as regular assessments of calcium homeostasis to ensure that the treatment is effective and to avoid the development of hypercalcemia which can lead to serious complications. It is vital to adhere to any testing schedules outlined by your healthcare provider when taking Alfacalcidol to ensure effective use and to monitor for any potential side effects or unintended consequences. The specific testing regime and timing of the tests would be advised by the prescribing physician who can tailor the monitoring to the individual based on their clinical condition and response to the medication.
