Alfa-D (0.25mcg) 10 Tablets

Alfacalcidol, the active ingredient in the 0.25 microgram tablet, is a synthetic analog of vitamin D. Its mechanism of action primarily involves mimicking the effects of naturally occurring vitamin D metabolites in the body. Alfacalcidol is metabolized in the liver to form 1,25-dihydroxyvitamin D, the active form of vitamin D. This active metabolite binds to vitamin D receptors (VDRs) in various target tissues, primarily in the intestine, kidneys, and bones. By activating VDRs, alfacalcidol promotes the absorption of calcium and phosphate from the intestines, increases renal tubular reabsorption of calcium, and mobilizes calcium and phosphate from bone. These actions collectively contribute to the maintenance of calcium and phosphate homeostasis, promoting bone mineralization and preventing hypocalcemic conditions. Alfacalcidol's mechanism of action makes it useful in the treatment of various conditions related to calcium and vitamin D metabolism disorders.

Following are the drug interactions for Alfacalcidol 0.5ug Tablet:

• Anticonvulsants like phenytoin or carbamazepine may decrease the effectiveness of Alfacalcidol.
• Thiazide diuretics can enhance the effects of Alfacalcidol, requiring careful monitoring.
• Calcium-containing antacids may reduce Alfacalcidol absorption when taken simultaneously.
• Corticosteroids such as prednisone can increase calcium excretion, requiring dose adjustments.
• Taking digoxin with Alfacalcidol may lead to elevated calcium levels, necessitating close monitoring.
• Mineral oil laxatives can interfere with Alfacalcidol absorption, so separate administration is advised.
• Certain antibiotics like tetracyclines may have reduced absorption when taken with Alfacalcidol.

Following are the food interactions for Alfacalcidol 0.25ug Tablet:

• Alfacalcidol may interact with calcium-rich foods like milk, cheese, and yogurt, as well as calcium supplements. These can affect the absorption and effectiveness of the medication.
• Avoid excessive consumption of foods rich in vitamin D, such as fatty fish, egg yolks, and fortified dairy products, as it may lead to vitamin D toxicity.
• Grapefruit and grapefruit juice should be limited as they can interfere with the metabolism of Alfacalcidol, potentially raising its levels in the blood.
• Alcohol can increase the risk of kidney damage when used with Alfacalcidol, so it's best to limit or avoid alcohol consumption.
• Avoid high-phosphorus foods like red meat, organ meats, and carbonated beverages, as phosphorus can affect calcium and vitamin D metabolism.
