It is a sulfonamide antibiotic used for intestinal infections. Its combination with trimethoprim can doubly block the bacterial folate synthesis metabolism, resulting in a synergistic effect. It can enhance the antibacterial activity of sulfonamides, convert the antibacterial effect into a bactericidal effect, and reduce the production of drug-resistant strains.

When used in combination with sulfonamides, the bacterial folate anabolism can be doubly blocked, resulting in a synergistic effect. This can enhance the antibacterial activity of sulfonamides, convert the antibacterial effect into a bactericidal effect, and reduce the production of drug-resistant strains.

It inhibits the influx of Na+, Ca2+ and other ions across the cell membrane, and has a stabilizing effect on the cell membrane of excitable cells such as bronchial smooth muscle and inflammatory cells; it works synergistically with other ingredients to have significant antiasthmatic and antitussive effects.

Block histamine H1 receptors, relax bronchial smooth muscles, alleviate allergic reactions, and reduce capillary permeability.

Stimulate beta 2 receptors, promote the release of norepinephrine from nerve endings, enhance diaphragm contraction, improve respiratory function; constrict airway blood vessels, and inhibit congestion and edema.

By changing mucin synthesis to reduce viscosity, it promotes airway ciliary movement and enhances diaphragmatic contractility.

Similar to theophylline, it has certain antiasthmatic and expectorant effects.

Relaxes bronchial smooth muscle, reduces viscosity, and promotes airway ciliary movement.

Block bronchial smooth muscle cholinergic M receptors, relax bronchial smooth muscle, and reduce bronchial secretions.

This product belongs to the nitrate compound, which has the effect of preventing the free calcium ions in cells, increasing the permeability of cell membrane 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.

Selective beta-2 receptor agonist, can relieve bronchial smooth muscle spasm

Expectorants can reduce the viscosity of bronchial mucus, making sputum thinner and easier to cough up

Antibacterial and anti-inflammatory

Antihistamines, which can relieve wheezing caused by bronchial smooth muscle contraction and have a central sedative effect

This product is an antibacterial drug. Escherichia coli is mostly sensitive to this product, and some strains of Enterobacteriaceae such as Enterobacter aerogenes, Enterobacter cloacae, Proteus, and Klebsiella are sensitive to this product. Pseudomonas aeruginosa is usually resistant to this product. This product has antibacterial effects on Gram-positive bacteria such as Enterococcus. The antibacterial activity of this product is not affected by pus and tissue decomposition products. It is more active in acidic urine. The antibacterial mechanism is to interfere with the oxidoreductase system in the bacteria, thereby blocking its metabolic process.
