Ostiozer Softgel Capsule is a combination supplement formulated to support bone health and calcium metabolism. Each softgel contains Calcitriol 0.25 mcg, Calcium Carbonate 500 mg, and Zinc Sulfate 7.5 mg, providing a synergistic effect to enhance calcium absorption and promote bone mineralization. Calcitriol, the active form of vitamin D3, plays a crucial role in regulating calcium and phosphate homeostasis by increasing intestinal absorption of calcium. Calcium Carbonate serves as a vital mineral for maintaining bone strength and structural integrity, while Zinc Sulfate contributes to bone formation and repair through its involvement in collagen synthesis and cellular function. Ostiozer is indicated for the prevention and treatment of calcium deficiencies, osteoporosis, and conditions associated with impaired bone metabolism such as hypocalcemia and osteomalacia. It is particularly beneficial in patients with inadequate dietary calcium intake or those at risk of bone demineralization due to aging, postmenopausal status, or certain metabolic disorders. The softgel formulation ensures ease of administration and improved bioavailability. Ostiozer should be used under medical supervision, with dosage tailored to individual patient needs, and caution advised in patients with hypercalcemia, renal impairment, or hypersensitivity to any component. Regular monitoring of serum calcium and renal function is recommended during therapy.
