It has obvious anti-acid effect, and also has gastric mucosal protective effect. It also has a certain adsorption effect on bile acid. Its effect is rapid, mild and long-lasting.

Unspecified

1. Calcium influx blocker, blocking extracellular calcium ions from entering myocardial and vascular smooth muscle cells; 2. Directly relaxes vascular smooth muscle and has anti-hypertensive effect; 3. Relieves myocardial ischemia, reduces peripheral resistance by dilating peripheral arterioles, and reduces myocardial energy consumption and oxygen demand; 4. Dilates coronary arteries and coronary arterioles to increase myocardial oxygen supply; 5. It takes a long time to metabolize in the liver, so it should be used with caution when liver function is impaired.

It achieves its antibacterial effect by inhibiting the activity of bacterial DNA gyrase and hindering bacterial replication. It has good antibacterial effects on most Enterobacteriaceae, some Gram-positive bacteria, Legionella, Mycoplasma, Chlamydia, etc., but has poor effects on anaerobic bacteria and enterococci.

This product is a semi-synthetic 14-membered macrolide antibiotic. Its antibacterial spectrum and antibacterial effect are basically similar to those of erythromycin. Its effect on Gram-positive bacteria is slightly worse than that of erythromycin, and its effect on Legionella pneumophila is stronger than that of erythromycin. Its antimicrobial effect on Chlamydia pneumoniae, Mycoplasma pneumoniae, and Ureaplasma urealyticum is similar to or slightly stronger than that of erythromycin. This product can penetrate the bacterial cell membrane and reversibly bind to the 50S subunit of the bacterial ribosome near the donor (P position), blocking the transfer RNA (t-RNA) from binding to the P position, and also blocking the transfer of the polypeptide chain from the acceptor position (A position) to the P position, thereby inhibiting bacterial protein synthesis.
