Maintain normal blood and extracellular fluid volume and osmotic pressure in the human body; sodium and chloride are important electrolytes in the body, accounting for the main part of plasma cations and total osmotic pressure.

Replenish potassium ions and participate in maintaining body fluid volume and electrolyte balance.

Replenish calcium ions to help maintain body fluid volume and electrolyte balance.

Maintains normal blood and extracellular fluid volume and osmotic pressure in the human body; plays a decisive role in osmotic pressure

Supplement a small amount of potassium ions to maintain the stability of body fluid volume and osmotic pressure

Supplement a small amount of calcium ions to maintain the stability of body fluid volume and osmotic pressure

Restores the imbalance between the excitation and inhibition processes of the cerebral cortex, and has central inhibitory effects such as sedation, hypnosis and analgesia

Metronidazole has a strong antibacterial effect on most anaerobic bacteria, but has no effect on aerobic bacteria and facultative anaerobes. The antibacterial spectrum includes Bacteroides fragilis and other Bacteroides, Fusobacterium, Clostridium perfringens, Eubacterium, Veillonella, Peptococcus and Peptostreptococcus. Actinomycetes, Lactobacillus and Propionibacterium are resistant to this product. Its bactericidal concentration is slightly higher than the inhibitory concentration. This product can also inhibit the redox reaction of amoeba and break the nitrogen chain of the protozoa. In vitro tests have shown that when the drug concentration is 1-2 mg/L, the histolytica can undergo morphological changes in 6-20 hours and all are killed within 24 hours. When the concentration is 0.2 mg/L, the histolytica can be killed within 72 hours. This product has a strong effect of killing trichomonas, and its mechanism is unknown. It has a carcinogenic effect on some animals.

This product is a first-generation cephalosporin, which has good antibacterial effect on some strains of Gram-positive cocci such as non-penicillinase-producing and penicillinase-producing Staphylococcus aureus, coagulase-negative Staphylococci, group A hemolytic streptococci, Streptococcus pneumoniae and viridans streptococci. Anaerobic Gram-positive bacteria are mostly sensitive to this product, and Bacteroides fragilis is resistant to this product. Methicillin-resistant Staphylococci and Enterococci are resistant to this product. The effect of this product on Gram-positive and Gram-negative bacteria is similar to that of cephalexin. This product has a certain effect on gonococci and is also active against enzyme-producing gonococci; its activity against Haemophilus influenzae is poor.
