GD 60 Injection contains Vitamin D3 (Cholecalciferol) at a concentration of 60,000 IU per dose, formulated for intramuscular administration. It is indicated for the prevention and treatment of Vitamin D deficiency and insufficiency, which may result from inadequate dietary intake, limited sunlight exposure, malabsorption syndromes, or certain metabolic disorders. Vitamin D3 plays a crucial role in calcium and phosphate homeostasis, promoting bone mineralization and maintaining skeletal health. GD 60 Injection is particularly useful in conditions such as rickets, osteomalacia, hypoparathyroidism, and secondary hyperparathyroidism associated with chronic renal failure. The high-dose formulation allows for rapid correction of Vitamin D levels, especially in patients requiring prompt intervention. Administration should be performed under medical supervision, with dosage tailored according to individual patient needs, baseline serum 25-hydroxyvitamin D levels, and clinical response. Monitoring of serum calcium and phosphate is recommended to avoid hypercalcemia and related complications. Contraindications include hypercalcemia, hypervitaminosis D, and hypersensitivity to any component of the formulation. GD 60 Injection should be used with caution in patients with renal impairment or granulomatous diseases. Proper storage and handling are essential to maintain potency and sterility.
