A-Cal D Tablet 500 mg+200 IU is a combination supplement containing Elemental Calcium and Vitamin D3 (Cholecalciferol). This formulation is designed to support optimal bone health by improving calcium absorption and maintaining adequate calcium levels in the body. Calcium and vitamin D3 work synergistically to strengthen bones and teeth, reduce bone loss, and prevent calcium deficiency–related disorders.

Indications

A-Cal D Tablet is indicated for the prevention and treatment of calcium and vitamin D deficiency and associated conditions, including:

• Calcium deficiency due to inadequate dietary intake

• Vitamin D deficiency

• Osteoporosis, including postmenopausal and senile osteoporosis

• Osteomalacia and rickets

• Increased calcium requirements during pregnancy and lactation

• Bone health support in elderly patients

• Adjunct therapy in fracture healing

• Long-term corticosteroid therapy–induced bone loss

Regular supplementation helps maintain bone density and reduces the risk of fractures.

Therapeutic Class

Calcium and vitamin D preparations

Pharmacology

Calcium is an essential mineral involved in bone mineralization, neuromuscular function, enzyme activity, and blood coagulation. Nearly 99% of the body’s calcium is stored in bones and teeth, providing structural support. The remaining calcium plays a vital role in metabolic functions.

Vitamin D3 enhances intestinal absorption of calcium and phosphate and helps regulate calcium balance by acting on the intestine, kidneys, and bones. Inadequate vitamin D levels reduce calcium absorption, leading to secondary hyperparathyroidism and bone demineralization. The combination of elemental calcium with vitamin D3 ensures effective calcium utilization and optimal skeletal health.

Mode of Action

Elemental calcium replenishes calcium stores required for bone strength and normal physiological functions. Vitamin D3 increases calcium absorption from the gastrointestinal tract and promotes proper bone mineralization. Together, they help prevent hypocalcemia, maintain bone density, and support muscle and nerve function.

Dosage and Administration

Dosage should be individualized based on age, nutritional status, and clinical condition:

• Adults: One tablet once or twice daily, or as directed by a physician

• Pregnancy and lactation: As prescribed by a healthcare professional

• Elderly patients: Dose adjusted according to calcium and vitamin D requirements

A-Cal D Tablet should be taken with meals to improve absorption. Adequate hydration is recommended during therapy.

Drug Interactions

Calcium may interfere with the absorption of tetracyclines, quinolones, bisphosphonates, and iron supplements. Vitamin D3 may interact with thiazide diuretics, increasing the risk of hypercalcemia. A gap of at least 2 hours is advised when taking interacting medicines.

Contraindications

A-Cal D Tablet is contraindicated in patients with:

• Hypercalcemia or hypervitaminosis D

• Severe renal impairment

• Nephrolithiasis (kidney stones)

• Hyperparathyroidism

Side Effects

The formulation is generally well tolerated. Possible side effects include mild gastrointestinal discomfort, constipation, nausea, bloating, or abdominal pain, particularly at higher doses.

Pregnancy and Lactation

A-Cal D Tablet is safe for use during pregnancy and lactation when taken within recommended doses, as both calcium and vitamin D are essential for fetal skeletal development and maternal bone health.

Storage Conditions

Store in a cool, dry place below 30°C. Protect from light and moisture. Keep out of reach of children.
