Calcium chloride is used to prevent or treat negative calcium balance. It also regulates action potential excitation threshold to facilitate nerve and muscle performance.

Potassium chloride is a major cation of the intracellular fluid. It plays an active role in the conduction of nerve impulses in the heart, brain and skeletal muscle; contraction of cardiac skeletal and smooth muscles; maintenance of normal renal function, acid-base balance, carbohydrate metabolism and gastric secretion.

Magnessium Chloride acts as cofactor in numerous enzymatic reactions involving protein synthesis and carbohydrate metabolism; depresses CNS, blocks peripheral neuromuscular transmission, produces anticonvulsant effects.

Sodium chloride is the major extracellular cation. It is important in electrolyte and fluid balance, osmotic pressure control and water distribution as it restores sodium ions. It is used as a source of electrolytes and water for hydration, treatment of metabolic acidosis, priming solution in haemodialysis and treatment of hyperosmolar diabetes. It is also used as diluents for infusion of compatible drug additives.
