This product is a non-narcotic antitussive drug that reduces the excitement of the cough center, reduces the lung stretch receptor reflex, and relaxes bronchial smooth muscle. The antitussive effect is 2-4 times that of codeine, but it is not addictive and has no drug resistance.

This product can directly penetrate the cell membrane into the body cells, activate pyruvate oxidase, so that cells in a low-energy and hypoxic state can continue to metabolize smoothly, and participate in the energy metabolism and protein synthesis of the human body.

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.
