This product is a medium-acting sulfonamide. It has antibacterial effects on non-enzyme-producing Staphylococcus aureus, Streptococcus pyogenes, Streptococcus pneumoniae, Escherichia coli, Klebsiella, Salmonella, Shigella and other Enterobacteriaceae, gonococci, meningococci, Haemophilus influenzae. In addition, it also has antimicrobial activity against Chlamydia trachomatis, Nocardia asteroides, Plasmodium and Toxoplasma in vitro. The antibacterial activity of this product is the same as that of sulfamethoxazole. However, in recent years, bacterial resistance to this product has increased, especially Streptococcus, Neisseria and Enterobacteriaceae. Sulfonamides are broad-spectrum antibacterial agents. This product is similar in structure to para-aminobenzoic acid (PABA), and can compete with PABA on dihydrofolate synthase in bacteria, thereby preventing PABA from being used as a raw material to synthesize folic acid required by bacteria, reducing the amount of metabolically active tetrahydrofolate, which is an essential substance for bacteria to synthesize purine, thymidine and deoxyribonucleic acid (DNA), thereby inhibiting the growth and reproduction of bacteria.

It can relax bronchial smooth muscles, shrink bronchial mucosal blood vessels, reduce congestion and edema, and improve airway obstruction.

It can reflexively increase the secretion of respiratory mucosal glands, making it easier to discharge sputum and facilitating the removal of sticky sputum.

It can relieve cough, expectorant and asthma.

Can clear the lungs and relieve asthma

It can increase the secretion of respiratory mucus, dilute sputum, and make it easier to cough up.

It is a mucosal protective antitussive drug that can cover the inflamed pharyngeal mucosa to reduce the stimulation of local sensory nerve endings, thereby exerting an antitussive effect.

Trimethoprim (TMP) is an antibacterial agent, a lipophilic weak base, and its chemical structure belongs to the pyrimethamine class. It has antibacterial activity against Escherichia coli, Klebsiella, Proteus mirabilis, Salmonella, and Shigella, but has no obvious antibacterial effect on Streptococcus pneumoniae, Neisseria gonorrhoeae, and Neisseria meningitidis, and has no effect on Pseudomonas aeruginosa. The mechanism of action of this product is to interfere with bacterial folic acid metabolism. It mainly selectively inhibits the activity of bacterial dihydrofolate reductase, so that dihydrofolate cannot be reduced to tetrahydrofolate, and synthetic folic acid is the main component of nucleic acid biosynthesis. Therefore, this product prevents the synthesis of bacterial nucleic acids and proteins, and the binding of this product to bacterial dihydrofolate reductase is 50,000 to 60,000 times tighter than that to mammalian enzymes. The combination of this product and sulfonamides can double block the bacterial folic acid synthesis metabolism, have a synergistic effect, enhance the antibacterial activity of sulfonamides, and convert the antibacterial effect into a bactericidal effect, reducing the production of drug-resistant strains.
