Azithromycin for injection

Azithromycin is a 15-membered macrolide antibiotic. In vitro tests have shown that azithromycin has antibacterial effects on a variety of common clinical pathogens, including: Gram-positive aerobic bacteria, Staphylococcus aureus, Streptococcus pyogenes (group A beta; hemolytic streptococci), pneumonia (streptococci), a-hemolytic streptococci (grass-green streptococci) and other streptococci, diphtheria (rod-shaped) bacilli. This product shows cross-resistance to erythromycin-resistant Gram-positive bacteria, including fecal streptococci (enterococci) and methicillin-resistant Staphylococcus aureus strains. Gram-negative aerobic bacteria: Haemophilus influenzae, Haemophilus parainfluenzae, Moraxella catarrhalis, Acinetobacter, Yersinia, Legionella pneumophila, Bordetella pertussis, Bordetella parapertussis, Shigella, Pasteurella, Vibrio cholerae, Parahaemolyticus, Shigella-like Pseudomonas. The activity of this product against the following Gram-negative bacteria depends on the strain, and sensitivity testing is required: Escherichia coli, Salmonella typhi, Enterobacter, Hydrophila, Klebsiella. Anaerobic bacteria: Bacteroides fragilis, Bacteroides, Clostridium perfringens, Peptostreptococcus, Fusobacterium necroticum, Propionibacterium acnes. Sexually transmitted disease microorganisms: Treponema pallidum, Neisseria gonorrhoeae, Haemophilus dukei. Other microorganisms: including Borrelia tenens (Lyme disease body), Mycoplasma pneumoniae, Mycoplasma hominis, Ureaplasma urealyticum, Chlamydia trachomatis, Pneumocystis carinii, Mycobacterium avium, Campylobacter, Listeria monocytogenes. The following Gram-negative bacteria are usually resistant: Proteus, Serratia, Morganella, Pseudomonas. The mechanism of action is the same as erythromycin, mainly binding to the 50S subunit of the bacterial ribosome, inhibiting RNA-dependent protein synthesis.

This product is a sterile lyophilized product of azithromycin lactobionate.

1. When used in combination with theophylline, the latter's concentration in plasma can be increased, and attention should be paid to detecting plasma theophylline levels. 2. When used in combination with warfarin, attention should be paid to checking the prothrombin time. 3. When used simultaneously with the following drugs, it is recommended to closely observe the patient: Digoxin increases digoxin levels. Ergotamine or dihydroergotamine causes acute ergot toxicity, with symptoms of severe peripheral vasospasm and dysesthesia (pain when touching objects). Triazolam enhances the pharmacological effects of triazolam by reducing its degradation. Cytochrome P450 system metabolites increase the levels of carbamazepine, terfenadine, cyclosporine, cyclohexylbarbital, and phenytoin in serum. 4. When used in combination with rifabutin, the latter's toxicity will be increased.

Keep away from light, tightly closed and in a dry place.
