Beta-2 receptor selective agonist. Its main pharmacological effects are to relax bronchial smooth muscle, inhibit the release of transmitters from mast cells, enhance mucus transport, prevent mucosal edema by inhibiting the release of endogenous transmitters, stimulate mucosal chloride pumps, and increase airway moisture. It has little effect on cardiac excitation, so it does not increase myocardial oxygen consumption, and will not induce or aggravate angina pectoris and arrhythmia.

Extract from the above information

It has only a weak antibacterial effect on bacteria, and has a certain inhibitory effect on Staphylococcus aureus, Haemophilus influenzae, Candida albicans, etc. It can increase the level of serum properdin and enhance the phagocytic ability of leukocytes.

This product is a methylhydroxyglutaryl coenzyme A (HMG-COA) reductase inhibitor, which inhibits the synthesis of endogenous cholesterol and is a blood lipid regulator. Literature data show that it can reduce the cholesterol (TC) content in the serum, liver, and aorta of hyperlipidemia rabbits, and reduce the levels of very low density lipoprotein cholesterol (VLDL-C) and low density lipoprotein cholesterol (LDL-C).
