1. It has obvious bronchodilator effect; 2. The duration of bronchodilator effect is longer than that of other similar drugs; 3. It has superior selectivity for beta 2-receptors; 4. It has anti-allergic effect and can inhibit immediate and delayed increase in airway reactivity; 5. It promotes respiratory cilia movement and increases respiratory defense ability; 6. It may prevent or alleviate the occurrence of exercise-induced asthma.

It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, beta-hemolytic Streptococcus, viridans Streptococcus and Streptococcus pneumoniae. It has good antibacterial effect on anaerobic bacteria, including Clostridium diphtheriae, and Clostridium perfringens. It has no activity against Gram-negative bacteria such as Enterococcus, meningococci, Neisseria gonorrhoeae, and Haemophilus influenzae, as well as fungi. There is no cross-resistance with penicillin, chloramphenicol, cephalosporins and tetracyclines, and there is partial cross-resistance with macrolides. It acts on the 50S subunit of the ribosome of sensitive bacteria, preventing the extension of the peptide chain, thereby inhibiting the protein synthesis of bacterial cells. It is generally an antibacterial agent, but at high concentrations, it also has a bactericidal effect on certain bacteria.

This product is an amide local anesthetic, which has a biphasic effect of excitation and inhibition on the central nervous system. At low doses, it can promote the outflow of K in myocardial cells, reduce the autonomy of the myocardium, and has an anti-ventricular arrhythmia effect; at therapeutic doses, it has no obvious effect on the electrical activity of myocardial cells, atrioventricular conduction and myocardial contraction; when the blood drug concentration is further increased, it can cause a slowing of heart conduction velocity, atrioventricular conduction block, inhibit myocardial contractility and reduce cardiac output.
