This product is a compound of aminopyrine and sodium sulfite. It is easily soluble in water and has faster and stronger antipyretic and analgesic effects than aminopyrine.

Analgesic, anti-inflammatory, antipyretic, reduces prostaglandin synthesis by inhibiting cyclooxygenase, reduces tissue congestion and swelling, reduces nerve pain sensitivity, and has an antipyretic effect through the hypothalamic temperature regulation center

It participates in many reactions in the body, such as participating in the redox process, and plays an important role in biological oxidation and reduction and cellular respiration. From the tissue level, the main role of vitamin C is related to the synthesis of intercellular matrix. Including collagen, tooth and bone matrix, and the junction between capillary endothelial cells. Therefore, when scurvy caused by vitamin C deficiency is accompanied by collagen synthesis defects, it is manifested as difficult wound healing, impaired tooth formation and capillary damage causing a large number of ecchymosis points, which merge to form ecchymosis.

Cephalexin is a first-generation cephalosporin with an antibacterial spectrum similar to that of cephalothin, but its antibacterial activity is poorer than that of the latter. Except for Enterococcus and methicillin-resistant Staphylococci, most strains of Streptococcus pneumoniae, hemolytic Streptococcus, and Staphylococcus aureus that produces or does not produce penicillinase are sensitive to this product. This product has a good antibacterial effect on Neisseria, but Haemophilus influenzae is less sensitive to this product; this product has a certain antibacterial effect on some Escherichia coli, Proteus mirabilis, Salmonella and Shigella. The remaining Enterobacteriaceae, Acinetobacter, Pseudomonas aeruginosa, and Bacteroides fragilis are resistant to this product. Fusobacterium and Veillonella are generally sensitive to this product, and anaerobic Gram-positive cocci are moderately sensitive to this product.

Tetracycline antibiotics. This product is a broad-spectrum antibacterial agent with bactericidal effects at high concentrations. Many Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria, and spirochetes are also sensitive to this product. This product is more effective against Gram-positive bacteria than Gram-negative bacteria, but Enterococcus is resistant to it. Others such as Actinomycetes, Bacillus anthracis, Listeria monocytogenes, Clostridium, Nocardia, Vibrio, Brucella, Campylobacter, and Yersinia are sensitive to this product. This product has certain antibacterial activity against Neisseria gonorrhoeae, but penicillin-resistant Neisseria gonorrhoeae is also resistant to doxycycline. Due to the widespread use of tetracyclines over the years, common clinical pathogens have become seriously resistant to this product, including Gram-positive bacteria such as Staphylococcus and most Gram-negative bacilli. 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 bacterial ribosome 30S subunit, inhibiting the growth of the peptide chain and affecting the synthesis of bacterial protein. Animal experiments have confirmed that this product is teratogenic. In vitro tests have shown that this product may be mutagenic at a certain concentration.
