Calcium is a macroelement involved in bone tissue formation, blood clotting, and is necessary to maintain stable cardiac activity and nerve impulse transmission processes. Improves muscle contraction in muscular dystrophy, myasthenia, and reduces vascular permeability. When administered intravenously, calcium excites the sympathetic nervous system and increases the secretion of adrenaline by the adrenal glands; it has a moderate diuretic effect.

Hypofunction of the parathyroid glands: latent tetany, osteoporosis. Disorders of vitamin D metabolism: rickets (spasmophilia, osteomalacia), hyperphosphatemia in patients with chronic renal failure. Increased calcium requirement: pregnancy, lactation, period of intensive growth. Increased calcium excretion: prolonged bed rest, chronic diarrhea, secondary hypocalcemia due to prolonged use of antiepileptic drugs, glucocorticosteroids. Allergic diseases: urticaria, itching, itchy dermatoses. Poisoning with Mg2+ salts, oxalic and fluoric acids and their soluble salts (when interacting with calcium gluconate, insoluble and non-toxic calcium oxalate and calcium fluoride are formed). Hyperkalemic form of proximal myoplegia.
