Azithromycin is a 15-membered macrolide antibiotic that has antibacterial effects on a variety of Gram-positive aerobic bacteria, Gram-negative aerobic bacteria, anaerobic bacteria, sexually transmitted disease microorganisms and other microorganisms. It mainly binds to the 50S subunit of the bacterial ribosome and inhibits RNA-dependent protein synthesis.

This product is a potassium supplement. Potassium ions are necessary to maintain cell metabolism, intracellular osmotic pressure and acid-base balance, nerve impulse conduction, muscle contraction, and myocardial contraction.

Aminoglycoside antibiotics have good antibacterial effects on Gram-negative and Gram-positive bacteria, and inhibit bacterial protein synthesis by binding to the 30S subunit of bacterial ribosomes. It is effective against Enterobacteriaceae, Neisseria, Haemophilus influenzae, Brucella, Yersinia pestis, Acinetobacter, etc. It has good antibacterial effects on about 80% of methicillin-sensitive Staphylococci, but has poor effects on Streptococcus and Streptococcus pneumoniae, and most Enterococci are resistant. Combination with β-lactams can achieve synergistic antibacterial effects. In recent years, the number of Gram-negative bacteria resistant to gentamicin has increased significantly.
