It has anti-thrombotic effects. It inhibits platelet aggregation and release, which may be achieved through the following mechanisms: 1. Inhibition of adenosine uptake by platelets, epithelial cells and erythrocytes; 2. Inhibition of phosphodiesterase (PDE) in various tissues; 3. Inhibition of thromboxane A2 (TXA2) formation; 4. Enhancement of the effect of endogenous PGI2. In addition, dipyridamole has a vasodilatory effect.

This product is a nitroimidazole derivative that can inhibit the redox reaction of amoeba and break the nitrogen chain of the protozoa. In vitro tests have shown that when the drug concentration is 1~2mg/L, the histolytica amoeba can undergo morphological changes in 6~20 hours and all are killed within 24 hours. When the concentration is 0.2mg/L, the histolytica amoeba can be killed within 72 hours. This product has a strong effect of killing trichomonas, and its mechanism is unknown. Metronidazole has a killing effect on anaerobic microorganisms, and the metabolites generated when it is reduced in the human body also have anti-anaerobic effects, inhibiting the synthesis of bacterial deoxyribonucleic acid, thereby interfering with the growth and reproduction of bacteria, and ultimately causing bacterial death. It has a carcinogenic effect on some animals.

It selectively inhibits succinate dehydrogenase in the muscles of the worm, affects the anaerobic metabolism of the muscles of the worm, and reduces energy production; it depolarizes the nerve muscles, causing continuous muscle contraction and paralysis; its cholinergic effect is beneficial to the excretion of the worm; it may have an inhibitory effect on the microtubule structure of the worm; it has immune regulation and immune excitation functions.

It has vasodilatory and central muscle relaxant effects. It can directly dilate vascular smooth muscle and inhibit multi-synaptic reflexes, reduce skeletal muscle tension, and relieve muscle rigidity and clonus caused by brain and spinal cord damage.

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.
