Quinolone antibiotics have a broad-spectrum antibacterial effect and have good antibacterial activity against most bacteria of the Enterobacteriaceae family, Haemophilus influenzae, Neisseria, Pseudomonas aeruginosa, and Staphylococcus aureus. They also have antibacterial activity against Mycobacterium leprae. They act on the A subunit of bacterial DNA helicase, inhibiting the synthesis and replication of bacterial DNA and causing bacterial death.

Lacidipine is a specific and highly effective calcium ion antagonist that is highly selective for calcium channels in vascular smooth muscle. Its main effects are to dilate peripheral arterioles, reduce peripheral vascular resistance and lower blood pressure.

By hindering the bacterial transpeptidation process, it inhibits bacterial protein synthesis and has antibacterial effects on a variety of Gram-positive aerobic bacteria, Gram-negative aerobic bacteria, anaerobic bacteria, sexually transmitted disease microorganisms and other microorganisms. The mechanism of action is the same as that of erythromycin, mainly binding to the 50S subunit of the bacterial ribosome to inhibit RNA-dependent protein synthesis.
