ATC Group: A12AA Calcium
Anatomical Therapeutic Chemical Classification System
Calcium carbonate releases, in a pH-dependent manner, calcium ions in the stomach. Calcium carbonate is widely used as antacid and extensively used as a dietary supplement.
Calcium is the most abundant mineral in the body, and is an essential body electrolyte. Homeostasis is mainly regulated by the parathyroid hormone, by calcitonin, and by the activated form of vitamin D. Calcium is a structural component of bones and teeth. It is also required for blood clotting, neurotransmitter release, muscle contraction and normal heartbeat.
Calcium gluconate is used in calcium deficiency. Calcium is necessary for the functional integrity of nerves and muscles. It is essential for muscle contraction, cardiac function and blood coagulation.
