A selective beta-2 receptor agonist, it has a strong and lasting effect of relaxing bronchial smooth muscles. It can enhance ciliary movement and dissolve mucus, but has little effect on the cardiovascular system.

Cefazolin is a first-generation cephalosporin with a broad antibacterial spectrum. Except for Enterococcus and methicillin-resistant Staphylococcus, this product has good antibacterial activity against other Gram-positive cocci, and Streptococcus pneumoniae and hemolytic Streptococcus are highly sensitive to this product. Diphtheria Corynebacterium, anthrax Bacillus, Listeria and Clostridium are also very sensitive to this product. This product has good antibacterial activity against some Escherichia coli, Proteus mirabilis and Klebsiella pneumoniae, but has poor antibacterial effect on Staphylococcus aureus. Salmonella typhi, Shigella and Neisseria are sensitive to this product, while other Enterobacteriaceae, Acinetobacter and Pseudomonas aeruginosa are resistant. Enzyme-producing Neisseria gonorrhoeae is resistant to this product; Haemophilus influenzae is only moderately sensitive. Gram-positive anaerobes and some Gram-negative anaerobes are mostly sensitive to this product. Bacteroides fragilis is resistant.

This product is a glucocorticoid drug. It has multiple pharmacological effects such as anti-inflammatory, anti-toxic, anti-shock and immunosuppressive. 1 Anti-inflammatory effect: It has an effect on inflammation caused by various causes except viruses. Glucocorticoids reduce and prevent tissue response to inflammation, thereby reducing the symptoms of inflammation, and can also inhibit the repair of tissues in the late stage of inflammation and reduce sequelae. 2 Immunosuppressive effect: Prevent or inhibit cell-mediated immune responses, delayed allergic reactions, and reduce the expansion of primary immune responses. 3 Anti-toxic and anti-shock effects: Glucocorticoids can improve the body's tolerance, reduce cell damage, and play a role in protecting the body. It also dilates blood vessels, enhances myocardial contractility, and improves microcirculation.
