Clarithromycin belongs to the class of semisynthetic macrolide antibiotics. Clarithromycin binds to the 50S subunit of bacterial ribosomes, thereby inhibiting its protein synthesis and producing an antibacterial effect. In vitro, it has good antibacterial activity against both standard strains and clinical isolates, and has significant antibacterial effects against a variety of aerobic and anaerobic Gram-positive or Gram-negative bacteria. Generally, the minimum inhibitory concentration (MIC) of clarithromycin is the logarithmic dilution concentration of the minimum inhibitory concentration of erythromycin. The results of in vitro pharmacodynamic studies have shown that clarithromycin can inhibit Legionella pneumophila and Mycoplasma pneumoniae, and kill Helicobacter pylori, and its activity under neutral conditions is stronger than that under acidic conditions. In vitro and in vivo data show that objective existence has a significant clinical effect on mycobacteria. In vivo data show that Enterobacter, Pseudomonas and other non-lactose metabolizing Gram-negative bacteria are insensitive to clarithromycin.

This product is the levorotatory form of tetramisole, which can selectively inhibit succinate dehydrogenase in the muscles of the worm, so that fumaric acid cannot be reduced to succinic acid, thereby affecting the anaerobic metabolism of the muscles of the worm and reducing energy production. When the worm comes into contact with it, it can depolarize the nerves and muscles, and the muscles will continue to contract and cause paralysis; the drug's cholinergic effect is conducive to the excretion of the worm. Its activity is about 1 to 2 times that of tetramisole (racemic form), but its toxic side effects are lower. In addition, the drug may have an inhibitory effect on the microtubule structure of the worm. Levamisole also has immune regulation and immune excitation functions.
