The antibacterial spectrum is similar to that of rifampicin. It has good antibacterial activity against tuberculosis and leprosy. When the dosage is 1/3 of that of rifampicin, similar or higher efficacy can be achieved. It has a good effect on Staphylococcus aureus and has certain antibacterial activity against some Escherichia coli. In addition, it also has an inhibitory effect on Chlamydia trachomatis.

It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, β-hemolytic Streptococcus, viridans Streptococcus and Streptococcus pneumoniae. It has good antibacterial effect against anaerobic bacteria, including Clostridium tetani, Corynebacterium diphtheriae and Clostridium perfringens. It has no activity against Gram-negative bacteria such as enterococci, 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.

Anti-angina drug. This product belongs to the nitrate compound, which has the effect of preventing the free calcium ions in cells, increasing the permeability of cell membranes to potassium ions, dilating coronary blood vessels, continuously increasing coronary blood flow, and inhibiting coronary artery spasm. When dilating coronary blood vessels, it does not affect blood pressure, heart rate, myocardial contractility, and myocardial oxygen consumption. This product also has the effect of inhibiting platelet aggregation and preventing thrombosis.
