This product is a semi-synthetic 14-membered macrolide antibiotic. Its antibacterial spectrum and antibacterial effect are basically similar to those of erythromycin. Its effect on Gram-positive bacteria is slightly worse than that of erythromycin, and its effect on Legionella pneumophila is stronger than that of erythromycin. Its antimicrobial effect on Chlamydia pneumoniae, Mycoplasma pneumoniae, and Ureaplasma urealyticum is similar to or slightly stronger than that of erythromycin. This product can penetrate the bacterial cell membrane and reversibly bind to the 50S subunit of the bacterial ribosome near the donor (P position), blocking the transfer RNA (t-RNA) from binding to the P position, and also blocking the transfer of the polypeptide chain from the acceptor position (A position) to the P position, thereby inhibiting bacterial protein synthesis.

It includes two types: thyroxine (T4) and triiodothyronine (T3). It has the function of promoting catabolism (heat-raising effect) and anabolism, and has an important influence on the normal metabolism and growth and development of the human body, and is very important for the development of the central nervous system of infants and young children. The basic function of thyroid hormone is to induce the synthesis of new proteins including special enzyme systems, regulate the metabolism of three major substances: protein, carbohydrates and fats, as well as water, salt and vitamins. Because thyroid hormone induces the synthesis of cell membrane Na-K pumps and enhances their activity, energy metabolism is enhanced. Thyroid hormone (mainly T3) binds to specific receptors in the nucleus, which undergo conformational changes to form dimers. The activated receptors bind to specific sequences on DNA, thereby regulating gene expression.

This product is a quinolone antibacterial drug that acts on bacterial DNA gyrase to interfere with bacterial DNA synthesis, thereby causing bacterial death. It has antibacterial effects on Gram-negative bacteria such as Escherichia coli, Klebsiella pneumoniae, Enterobacter aerogenes, Proteus mirabilis, Serratia, Salmonella typhi, Shigella, Pseudomonas aeruginosa, etc.
