Antipyretic, analgesic and anti-inflammatory effects

Selectively shrink the blood vessels of the nasal mucosa, eliminate congestion and swelling of the nasopharyngeal mucosa, and relieve symptoms of nasal congestion

In acute toxicity experiments, the LD50 in mice and rats was greater than 4000 mg/Kg. In subacute toxicity experiments, Wistar male and female rats were given 40 mg, 200 mg and 1000 mg/Kg per day for 5 weeks, and male and female rabbits were given 6 mg, 60 mg and 600 mg/Kg per day for 23 consecutive days. There were no special changes in the blood, urine and morphological observations of the test animals. In chronic toxicity experiments, Wistar male and female rats were given 6 mg, 60 mg and 600 mg/Kg per day for 26 consecutive weeks. There were no special changes in the general state, blood and urine examinations, and morphological observations of the test animals.

It has a broad-spectrum antibacterial effect, especially against aerobic Gram-negative bacteria. It has 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 also has good effects on Chlamydia trachomatis, Mycoplasma, and Legionella, and 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.
