Sodium chloride is an electrolyte supplement. Sodium and chloride are important electrolytes in the body, mainly present in extracellular fluid, and play a very important role in maintaining normal blood and extracellular fluid volume and osmotic pressure. The normal serum sodium concentration is 135-145mmol/L, accounting for 92% of plasma cations and 90% of total osmotic pressure, so the amount of plasma sodium plays a decisive role in osmotic pressure. The normal serum chloride concentration is 98-106mmol/L. Sodium and chloride ions in the human body are mainly regulated by the hypothalamus, posterior pituitary and kidneys to maintain the stability of body fluid volume and osmotic pressure.

It has a broad-spectrum antibacterial effect, especially high antibacterial activity against aerobic Gram-negative bacilli. It has good antibacterial activity in vitro against the following bacteria: most bacteria of the Enterobacteriaceae family, including Citrobacter, Enterobacter cloacae, Enterobacter aerogenes, Escherichia coli, Klebsiella, Proteus, Salmonella, Shigella, Vibrio, Yersinia, etc. It often has antibacterial activity against multi-drug resistant bacteria. It has high antibacterial activity against penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae, and Moraxella. It has antibacterial activity against most strains of Pseudomonas, such as Pseudomonas aeruginosa. It has antibacterial activity against methicillin-sensitive Staphylococci, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus, and Enterococcus faecalis. It has good resistance to Chlamydia trachomatis, Mycoplasma, and Legionella.

Levofloxacin is the L-isomer of ofloxacin (racemate) and is a quinolone antibacterial drug. Its antibacterial mechanism is to inhibit topoisomerase IV and DNA gyrase (topoisomerase II) required for bacterial DNA replication, transcription, repair and recombination. It has antibacterial effects on a variety of Gram-negative and Gram-positive bacteria, and has bactericidal activity when the concentration is equal to or slightly higher than the inhibitory concentration.
