It has a direct relaxing effect on the smooth muscles of the respiratory tract. Its bronchodilator effect is partly due to the promotion of the release of endogenous adrenaline and norepinephrine. It can counteract the contractile effect of adenine on the respiratory tract, enhance the contractility of the diaphragm, and improve respiratory function.

It has the effect of dissolving mucus and phlegm, acts on the mucous gland cells of the trachea and bronchus, secretes low-viscosity small-molecule mucin, reduces and dilutes the mucus and makes it easier to cough up, promotes the movement of respiratory mucosal cilia and has a nauseating expectorant effect.

It is a histamine H1 receptor blocker that can counteract allergic symptoms such as microvascular dilation and increased capillary permeability caused by histamine. It also has a mild sedative and M cholinergic receptor blocking effect.

Anti-anaerobic and anti-trichomonal drugs

Broad-spectrum antifungal drugs have antibacterial effects on a variety of superficial and deep fungi. Their mechanism of action is to inhibit the synthesis of fungal cell membranes and affect their metabolic processes.

Quaternary ammonium salt cationic surfactant, bactericidal against Gram-positive bacteria

This product belongs to the macrolide antibiotics, which is the ethyl succinate of erythromycin. It is more stable than erythromycin in gastric acid. It has antibacterial activity against Staphylococcus (except methicillin-resistant strains), all groups of streptococci and Gram-positive bacilli. Neisseria, Haemophilus influenzae, Bordetella pertussis, etc. are also sensitive to this product. This product also has antibacterial effects on various anaerobic bacteria except Bacteroides fragilis and Fusobacterium. It also has inhibitory effects on Legionella, Campylobacter fetus, some spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on some bacteria at high concentrations. This product can penetrate the bacterial cell membrane and form a reversible bond with the 50S subunit of the bacterial ribosome near the donor site (P site), blocking the transfer RNA (t-RNA) from binding to the P site, and also blocking the displacement of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis.
