It has a certain antibacterial effect on most Gram-positive and Gram-negative bacteria, and inhibits the early synthesis of bacterial cell walls, thereby blocking the synthesis of bacterial cell walls and causing their death.

It has a broad-spectrum antibacterial effect, especially against aerobic Gram-negative bacteria. It has high antibacterial activity against most bacteria of the Enterobacteriaceae family, penicillin-resistant Neisseria gonorrhoeae, enzyme-producing Haemophilus influenzae and Moraxella, Pseudomonas aeruginosa, etc. It has antibacterial activity against methicillin-sensitive Staphylococcus aureus, and only moderate antibacterial activity against Streptococcus pneumoniae, hemolytic Streptococcus and Enterococcus faecalis. It has good effects on Chlamydia trachomatis, Mycoplasma, and Legionella, and also has antibacterial activity against Mycobacterium tuberculosis and atypical mycobacteria. It has poor antibacterial activity against anaerobic bacteria. Ciprofloxacin is a bactericide that acts on the A subunit of bacterial DNA helicase, inhibiting DNA synthesis and replication, leading to bacterial death.

Rifampicin is a semi-synthetic broad-spectrum antibacterial drug of the rifamycin class, which has antibacterial activity against a variety of pathogenic microorganisms. The drug has a significant bactericidal effect on Mycobacterium tuberculosis and some non-tuberculous mycobacteria (including Mycobacterium leprae, etc.) both inside and outside the host cells. Rifampicin has a good antibacterial effect on aerobic Gram-positive bacteria, including enzyme-producing strains of Staphylococcus aureus and methicillin-resistant strains, Streptococcus pneumoniae, other Streptococcus, Enterococcus, Listeria, Bacillus anthracis, Clostridium perfringens, Corynebacterium diphtheriae, anaerobic cocci, etc. It also has a high degree of antibacterial activity against aerobic Gram-negative bacteria such as Neisseria meningitidis, Haemophilus influenzae, and Neisseria gonorrhoeae. Rifampicin also has a good effect on Legionella, and has an inhibitory effect on pathogens such as Chlamydia trachomatis, lymphogranuloma venereum, and psittacosis.

It has a strong antibacterial effect on most anaerobic bacteria, and its bactericidal mechanism has not yet been fully elucidated. The nitroreductase of anaerobic bacteria plays an important role in the energy metabolism of sensitive strains. The nitro group of this product is reduced to a cytotoxin, thereby acting on the DNA metabolism process of bacteria and promoting cell death.

It is a long-acting nonsteroidal anti-inflammatory analgesic. After entering the body, it is metabolized into diphenyl ethyl ester, which can inhibit the activity of cyclooxygenase, reduce the synthesis of prostaglandins, and produce anti-inflammatory, analgesic and antipyretic effects.

This product is a proteolytic enzyme that can decompose coagulated protein into peptones and a small amount of polypeptides with the participation of gastric acid.
