Timolol maleate is a non-selective β-adrenergic receptor blocker with no significant endogenous sympathomimetic activity and local anesthetic effect, and no direct inhibitory effect on the myocardium. The exact mechanism of its lowering intraocular pressure is still unclear, but it may be related to reducing aqueous humor production.

This product is a fluoroquinolone antibiotic with broad-spectrum antibacterial effect.

This product is a semi-synthetic 14-membered macrolide antibiotic. Its antibacterial spectrum and antibacterial effect are basically similar to those of erythromycin. It is slightly less effective than erythromycin against Gram-positive bacteria, but stronger than erythromycin against Legionella pneumophila. Its antimicrobial effect against 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 site), blocking the transfer RNA (t-RNA) from binding to the P site, and also blocking the transfer of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis.
