This product is a potent, highly selective 5-HT3 receptor antagonist with a strong antiemetic effect. It exerts an antiemetic effect by antagonizing the 5-HT receptors of neurons located in the peripheral and central nervous systems, and is used for nausea and vomiting caused by chemotherapy, radiotherapy, and surgery. In addition, this product can also inhibit nausea induced by opioids, but its specific mechanism of action is still unclear. Due to the high selectivity of this product, it does not have the side effects of other antiemetics, such as extrapyramidal reactions and excessive sedation.

Quinolone antibacterial drugs inhibit bacterial DNA helicase and have a broad-spectrum antibacterial effect. They have strong antibacterial activity against Enterobacter bacteria such as Escherichia coli, Klebsiella, Proteus, Shigella, Salmonella typhi, etc., as well as influenza bacillus and Neisseria. They also have certain antibacterial effects on Staphylococcus aureus and Pseudomonas aeruginosa. They have only mild effects on pneumococci, various groups of streptococci and enterococci.

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.
