This product is a calcium supplement. Calcium can maintain the normal excitability of nerves and muscles and promote the secretion of acetylcholine by nerve endings. When serum calcium is low, the excitability of nerves and muscles may increase, resulting in convulsions. When blood calcium is too high, the excitability may decrease, resulting in weakness, etc. Calcium ions can improve the permeability of cell membranes, increase the density of capillaries, reduce exudation, and have an anti-allergic effect. Calcium ions can promote the calcification of bones and teeth. There is a competitive antagonism between high concentrations of calcium ions and magnesium ions, which can be used to rescue magnesium poisoning; calcium ions can react with fluoride to form insoluble calcium fluoride, which can be used to rescue fluoride poisoning.

A non-addictive analgesic with strong analgesic, local anesthesia, cooling, antipyretic, anti-inflammatory and detumescent effects. Its analgesic effect is comparable to that of pethidine, but with a slightly slower onset and longer duration of action; its analgesic effect is 7 times that of the antipyretic analgesic aminopyrine.

It can inhibit the synthesis of eukaryotic cell proteins, disaggregate polyribosomes, and interfere with the function of protein ribosomes. It also has an inhibitory effect on the synthesis of intracellular DNA. It has the strongest killing effect on G1 and G2 phase cells, but has a smaller effect on S phase cells. It has no cross-resistance with cytarabine, mercaptopurine, etc.

This product is a respiratory stimulant that can stimulate the respiratory center and excite breathing.
