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.

This product belongs to the macrolide antibiotics, which is the dodecyl sulfate of erythromycin propionate. It has antibacterial activity against Staphylococcus, various groups of streptococci and Gram-positive bacilli. Neisseria, Haemophilus influenzae, Bordetella pertussis, etc. may also be sensitive to this product. This product also has antibacterial activity against various anaerobic bacteria except Bacteroides fragilis and Fusobacterium; it also has inhibitory effects on Legionella, Campylobacter fetus, some spirochetes, Mycoplasma pneumoniae, Rickettsia and Chlamydia. This product is an antibacterial agent, but it also has a bactericidal effect on some bacteria at high concentrations. This product can pass through the bacterial cell membrane and reversibly bind to the 50S subunit of the bacterial ribosome near the donor site (P site), blocking the transfer RNA (t-RNA) binding to the P site, and also blocking the displacement of the polypeptide chain from the acceptor site (A site) to the P site, thereby inhibiting bacterial protein synthesis. This product is only effective against bacteria with active division.
