Not clearly stated

By inhibiting bacterial DNA gyrase and topoisomerase IV, it inhibits bacterial DNA replication, transcription and repair processes. It has antibacterial activity against most strains of the following microorganisms: 1. Gram-positive bacteria: Staphylococcus aureus (limited to strains sensitive to methicillin), Streptococcus pneumoniae (strains sensitive to penicillin). 2. Gram-negative bacteria: Escherichia coli, Haemophilus influenzae and parainfluenzae, Klebsiella pneumoniae, Moraxella catarrhalis, Neisseria gonorrhoeae, Proteus mirabilis. 3. Other microorganisms: Chlamydia pneumoniae, Legionella pneumophila, Mycoplasma pneumoniae.

Extract from the above information

This product belongs to the quinolone antibacterial drug. Its main mechanism of action is to inhibit the activity of DNA gyrase and DNA topoisomerase IV of Staphylococcus aureus, hinder DNA synthesis and cause bacterial death; it has a weak inhibitory effect on human topoisomerase II. This product has the characteristics of a broad antibacterial spectrum and strong antibacterial effect. It has good antibacterial activity against G+ bacteria such as Staphylococcus, Streptococcus, Enterococcus, and against G- bacteria such as Escherichia coli, Proteus mirabilis, Klebsiella, Enterobacter cloacae, Citrobacter rodentium, Acinetobacter calcoaceticus, Haemophilus influenzae, Moraxella catarrhalis, Pseudomonas aeruginosa, etc. This product also has good antibacterial activity against some anaerobic bacteria such as Clostridium perfringens, Fusobacterium nucleatum, Propionibacterium acnes, Porphyromonas, some Peptostreptococci, Bacteroides fragilis and Prevotella.

This product is a vitamin drug. Fursultiamine is a new derivative of vitamin B1. It is quickly converted into active thiamine in the body and is not decomposed by thiaminase in the body. It has strong affinity for tissues, high concentration in organs, high concentration in blood, and long maintenance time. It has the characteristics of high efficiency, long-term effect and low toxicity. Like vitamin B1, active thiamine combines with pyrophosphate in the body to form coenzyme, participates in the oxidative decarboxylation reaction of pyruvate and a-ketoglutaric acid in sugar metabolism, and is necessary for sugar metabolism. When it is deficient, oxidation is blocked to form pyruvate, lactic acid accumulates, and affects the body's energy supply. Its symptoms are mainly manifested in the nervous and cardiovascular systems, and multiple peripheral neuritis affecting both sensory nerves and motor nerves occurs, manifested as paresthesia, neuralgia, limb weakness, and muscle soreness and atrophy. In terms of cardiovascular, due to the increase of acetone and lactic acid in the blood, the small arteries are dilated, the diastolic pressure decreases, and the myocardial metabolism is disturbed, so it is easy to have symptoms of heart failure such as palpitations, shortness of breath, chest tightness, cardiac hypertrophy, liver and lung congestion and peripheral edema. Digestive tract symptoms include decreased appetite leading to weakness and weight loss.
