Entacal-K2 Tablet is a combination pharmaceutical formulation containing Calcitriol (25 mcg), Calcium Carbonate (1200 mg), and Vitamin K2-7 (50 mcg), designed to support bone health and calcium metabolism. Calcitriol, the active form of vitamin D3, plays a crucial role in enhancing intestinal absorption of calcium and phosphate, thereby aiding in the maintenance of adequate serum calcium levels essential for normal bone mineralization. Calcium Carbonate serves as a vital calcium supplement to prevent or treat calcium deficiencies, contributing to the structural integrity of bones and teeth. Vitamin K2-7 (menaquinone-7) is included for its role in activating osteocalcin, a calcium-binding protein that facilitates the incorporation of calcium into the bone matrix, thus improving bone density and reducing the risk of fractures. This combination is particularly beneficial in conditions such as osteoporosis, hypocalcemia, and other metabolic bone diseases where calcium and vitamin D metabolism are impaired. Entacal-K2 is intended for oral administration and should be used under medical supervision, especially in patients with hypercalcemia, renal impairment, or those receiving concurrent medications affecting calcium homeostasis. Regular monitoring of serum calcium and renal function is recommended during therapy to ensure safety and efficacy.
