It inhibits the demethylation of 14alpha-sterol mediated by cytochrome P450 in fungi, thereby inhibiting the biosynthesis of ergosterol. It has a bactericidal effect on Candida, Aspergillus and other pathogenic fungi.

This product is a broad-spectrum antibacterial drug that is effective against both Gram-positive and Gram-negative bacteria. Bacteria are not easy to develop resistance to this product. There is no cross-resistance between similar drugs and antibiotics. This product has strong antibacterial activity against Gram-negative bacteria, especially bacteria of the Enterobacteriaceae family, such as Escherichia coli, Shigella, Klebsiella, Proteus, Enterobacter aerogenes, Serratia, Citrobacter, etc., which are highly sensitive to this product, and the minimum inhibitory concentration is generally less than 0.5μg/ml. Influenza bacillus is also highly sensitive to this product. Neisseria gonorrhoeae is sensitive to this product, and the minimum inhibitory concentration is 0.125μg/ml. This product also has an effect on Pseudomonas aeruginosa and other Pseudomonas, but requires a higher concentration, with a minimum inhibitory concentration of 4 to 32μg/ml; because the concentration of this product in urine exceeds the above concentration by several to more than ten times, it is still effective in treating Pseudomonas aeruginosa urinary tract infections. Among Gram-positive cocci, this product is more sensitive to Staphylococcus aureus and Staphylococcus epidermidis, and the lowest concentration for inhibiting 90% of bacteria is about 1-2μg/ml. The lowest concentration for inhibiting 90% of enterococci and pneumococci is about 4μg/ml and 16μg/ml.

This product is a broad-spectrum antibacterial drug that is effective against both Gram-positive and Gram-negative bacteria. Bacteria are not easy to develop resistance to this product, and there is no cross-resistance between similar drugs and antibiotics. It has strong antibacterial activity against Gram-negative bacteria, especially bacteria of the Enterobacteriaceae family (such as Escherichia coli, Shigella, Klebsiella, etc.), which are highly sensitive; influenza bacilli and gonococci are also sensitive to it; it has an effect on Pseudomonas aeruginosa and other Pseudomonas, and can be used to treat urinary tract infections caused by them; it is relatively sensitive to Staphylococcus aureus and Staphylococcus epidermidis, and also has a certain inhibitory effect on enterococci and pneumococci.

This product is a semi-synthetic ergot alkaloid derivative. It has alpha receptor blocking and vasodilation effects. It can enhance the metabolism of brain cell energy and increase the utilization of oxygen and glucose. It promotes the conversion of neurotransmitter dopamine to increase nerve conduction, strengthens the synthesis of brain protein, and improves brain function.

Aminoglycoside antibiotics, with an antibacterial spectrum similar to kanamycin but with weaker antibacterial effect, have good antibacterial activity against Escherichia coli, Klebsiella, Proteus and other Enterobacteriaceae, also have good effects on some Staphylococci (methicillin-sensitive strains), Neisseria gonorrhoeae, Neisseria meningitidis, have weak effects on Mycobacterium tuberculosis and Streptococcus, and have no effect on Pseudomonas aeruginosa and anaerobic bacteria. Bacteria have cross-resistance to this product and kanamycin. It mainly binds to the 30S subunit of bacterial ribosomes and inhibits bacterial protein synthesis. This product is less toxic than kanamycin.
