This product is an adrenal cortex hormone drug. External use can shrink dermal capillaries, inhibit the proliferation or regeneration of epidermal cells, inhibit the regeneration of fibroblasts in connective tissue, stabilize intracellular lysosomal membranes, and prevent tissue damage caused by the release of lysosomal enzymes. It has strong anti-inflammatory and anti-allergic effects.

Dopamine-mimetic anti-Parkinson's disease drugs, as precursors of dopamine synthesis in the body, enter the central nervous system through the blood-brain barrier and are converted into dopamine by dopa decarboxylase, thus improving the symptoms of Parkinson's disease. They can also increase neurotransmitters such as dopamine and norepinephrine in the brain, increase the brain's tolerance to ammonia, and are used to treat hepatic coma, improve central nervous system function, awaken patients, and improve symptoms.

This product is a broad-spectrum antibacterial agent with bactericidal effect at high concentrations. In addition to common Gram-positive bacteria, Gram-negative bacteria and anaerobic bacteria, most Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria and spirochetes are also sensitive to this product. This product is better than Gram-positive bacteria for Gram-negative bacteria, but Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, etc. are sensitive to this product. This product has certain antibacterial activity against Neisseria gonorrhoeae, but penicillin-resistant gonococci are also resistant to tetracycline. This product has good antibacterial effect on Gram-negative bacteria such as Vibrio, Yersinia pestis, Brucella, Campylobacter, Yersinia, etc., has no antibacterial activity against Pseudomonas aeruginosa, and has certain antibacterial effect on some anaerobic bacteria, but it is far inferior to metronidazole, clindamycin and chloramphenicol, so it is not used clinically. Due to the widespread use of tetracyclines over the years, most common clinical pathogens, including Gram-positive bacteria such as Staphylococcus and Gram-negative bacteria such as Enterobacter, are resistant to tetracyclines, and there is cross-resistance between similar products. The mechanism of action of this product is that the drug can specifically bind to the A position of the 30S subunit of the bacterial ribosome, preventing the binding of aminoacyl-tRNA at this position, thereby inhibiting the growth of the peptide chain and affecting the synthesis of bacterial proteins.

It can counteract the capillary dilation caused by allergic reactions, reduce capillary permeability, have a mild bronchial smooth muscle spasmolysis effect, and also has a significant central nervous system sedative effect and a certain antitussive effect.

A strong expectorant that increases the secretion of respiratory glands, dilutes sputum, and makes it easier to cough up.

Salt expectorants can reflexively increase the secretion of respiratory mucosal glands, making sputum easier to cough up and facilitating the removal of sticky sputum.
