Liaoyuan DI KANG Pharmaceutical Limited Liability Company

It has an inhibitory effect on a variety of Gram-positive and Gram-negative bacteria in vitro, and has a stronger inhibitory effect on hemolytic Streptococcus, Staphylococcus aureus, Vibrio cholerae, Neisseria meningitidis, Shigella, Salmonella typhi, Corynebacterium diphtheriae, etc. It also has a certain inhibitory effect on amoeba.

It mainly interferes with bacterial folate metabolism, selectively inhibits dihydrofolate reductase, and prevents nucleic acid synthesis.

It has high antibacterial activity against common aerobic Gram-positive bacteria, such as Staphylococcus aureus (including those resistant to penicillin G), Staphylococcus epidermidis, β-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 between this product and 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.

Inhibits the influx of Na+ and Ca2+ ions across the cell membrane, and stabilizes the cell membrane of excitable cells such as bronchial smooth muscle and inflammatory cells

Blocks bronchial smooth muscle choline M receptors and histamine H1 receptors, relaxes bronchial smooth muscle

Stimulate beta 2 receptors, promote the release of norepinephrine from nerve endings, enhance diaphragmatic contraction, and improve respiratory function

This product is a compound preparation mainly based on phenytoin sodium and contains a variety of drugs with different mechanisms of action. Its main mechanism of action is: inhibiting the influx of Na+ and Ca2+ ions across the cell membrane, stabilizing the cell membrane of excitable cells such as bronchial smooth muscle and inflammatory cells; ephedrine hydrochloride stimulates beta;2 receptors, promotes the release of norepinephrine from nerve endings, enhances the contraction of the diaphragm, and is beneficial to improving respiratory function. Belladonna fluid extract and chlorpheniramine maleate can block the choline M receptors and histamine H1 receptors of bronchial smooth muscle, respectively, and relax bronchial smooth muscle. In addition, this product also has the effects of stimulating alpha; receptors on airway vascular smooth muscle, contracting airway blood vessels, inhibiting congestion and edema; inhibiting the release of allergic mediators, reducing capillary permeability; reducing viscosity by changing mucin synthesis; promoting airway ciliary movement, and enhancing diaphragmatic contraction. There is a good synergistic effect between the components of this product. Experiments have shown that this product has a good effect on histamine and acetylcholine. It has a significant antiasthmatic effect on asthma caused by antigens, and has a significant antitussive effect on various experimental coughs. This product also has a certain expectorant effect.

Blocks bronchial smooth muscle cholinergic M receptors, relaxes bronchial smooth muscle

Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent. Many Rickettsia, Mycoplasma, Chlamydia, and Spirochete are sensitive to this product. Enterococci are resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, Yersinia, etc. are also sensitive to this product. There is cross-resistance between this product and different varieties of tetracycline antibiotics. 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, inhibit the growth of the peptide chain and affect the synthesis of bacterial proteins.

This product is an analogue of diphenhydramine, which mainly suppresses cough center and relieves cough. It also has a weak antihistamine effect and has no dependence or tolerance. It takes effect 20-30 minutes after taking it and the effect lasts for 3-4 hours.
