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.

Aminoglycoside antibiotics have antibacterial effects on most Enterobacteriaceae, Pseudomonas aeruginosa, some other Pseudomonas, Acinetobacter, Alcaligenes, meningococci, gonococci, influenza bacilli, Yersinia, Campylobacter fetus, Mycobacterium tuberculosis and some Mycobacterium. They are stable to the aminoglycoside inactivating enzymes produced by many intestinal Gram-negative bacilli. Their mechanism of action is to act on the 30S subunit of bacterial ribosomes and inhibit bacterial protein synthesis. Combination with semi-synthetic penicillins or cephalosporins often produces synergistic antibacterial effects.

This product is a competitive angiotensin converting enzyme inhibitor, which prevents angiotensin I from being converted into angiotensin II, thereby reducing peripheral vascular resistance and reducing water and sodium retention by inhibiting aldosterone secretion. This product can also dilate peripheral blood vessels by interfering with the degradation of bradykinin. For patients with heart failure, this product can also reduce capillary wedge pressure and pulmonary vascular resistance, increase cardiac output and exercise tolerance time.

This product is a nitrofuran antibacterial drug. It has certain antibacterial effects on both Gram-positive and Gram-negative bacteria, including Salmonella, Shigella, Escherichia coli, Klebsiella pneumoniae, Enterobacter, Staphylococcus aureus, Enterococcus faecalis, Streptococcus pyogenes, Vibrio cholerae, Campylobacter, Bacteroides, etc. It is also active against Trichomonas and Giardia at a certain concentration. Its mechanism of action is to interfere with bacterial oxidoreductase and thus block the normal metabolism of bacteria.

It has an inhibitory effect on a variety of Gram-positive and Gram-negative bacteria in vitro, and has a stronger inhibitory effect on hemolytic Streptococcus, Staphylococcus aureus, Vibrio cholerae, Neisseria meningitidis, Shigella, Salmonella typhi, Corynebacterium diphtheriae, etc. It also has a certain inhibitory effect on amoeba.

It mainly interferes with bacterial folate metabolism, selectively inhibits dihydrofolate reductase, and prevents nucleic acid synthesis.
