It can inhibit the synthesis of prostaglandins and has antipyretic and analgesic effects.

It has the effect of constricting the capillaries in the upper respiratory tract, eliminating congestion in the nasopharyngeal mucosa and alleviating symptoms of nasal congestion.

It is an antihistamine with strong antihistamine and sedative effects, which can further alleviate symptoms such as nasal congestion and runny nose caused by colds.

This product is one of the ingredients of the Chinese medicine bezoar. As an endogenous amino acid, this product is a central inhibitory transmitter that can regulate the excitability of nerve tissue and body temperature, so it has antipyretic, sedative, analgesic, anti-inflammatory, anti-rheumatic, anticonvulsant and other effects. In addition, it can improve the body's nonspecific immune function.

It has a direct relaxant effect on the smooth muscles of the respiratory tract; it achieves bronchial dilation in part by releasing endogenous adrenaline and norepinephrine; it acts as a purine receptor blocker to counteract the contractile effect of adenine and other substances on the respiratory tract; it enhances the contractility of the diaphragm and improves respiratory function.

It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, beta-hemolytic Streptococcus, viridans Streptococcus and Streptococcus pneumoniae. It has good antibacterial effect on anaerobic bacteria, including Clostridium 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.

The antibacterial spectrum is the same as that of lincomycin, and the antibacterial activity is 4 to 8 times stronger than that of lincomycin. It has high antibacterial activity against aerobic Gram-positive cocci, such as Staphylococcus (including penicillin-resistant and methicillin-sensitive strains), hemolytic streptococci, grass-green streptococci, and Streptococcus pneumoniae. It also has good antibacterial effects on anaerobic bacteria. Most of the genera, such as Bacteroides, Fusobacterium, Actinomyces, Peptococci, and Peptostreptococci are sensitive to this product. 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.
