This product is a broad-spectrum semi-synthetic cephalosporin antibiotic. Its activity against penicillinase-producing Staphylococcus aureus, group A hemolytic streptococci, viridans streptococci and Staphylococcus epidermidis is the same as that of cefadroxil, and its antibacterial effect against non-enzyme-producing Staphylococcus aureus and pneumococci is 2 to 4 times stronger than that of cefadroxil. Its activity against Gram-negative bacilli, including Escherichia coli and Klebsiella pneumoniae, is stronger than that of cefadroxil, and is similar to that of cefadroxil. Its activity against Proteus mirabilis, Salmonella and Shigella is stronger than that of cefadroxil. 2.9 to 8 mg/L of this product can inhibit all Haemophilus influenzae, including strains resistant to ampicillin. Moraxella catarrhalis and Neisseria gonorrhoeae are very sensitive to this product. Indole-positive Proteus, Serratia, Acinetobacter and Pseudomonas aeruginosa are all resistant to this product. The mechanism of action of this product is to inhibit the synthesis of bacterial cell walls.

It is a highly selective 5-HT3 receptor antagonist, which has a good preventive and therapeutic effect on nausea and vomiting caused by radiotherapy, chemotherapy and surgery. It inhibits the occurrence of nausea and vomiting by antagonizing the 5-HT3 receptors in the central chemoreceptor area and peripheral vagus nerve endings. This product has high selectivity and no adverse reactions such as extrapyramidal reactions and excessive sedation.
