Azithromycin Granules

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), hemolytic streptococci (grass viridans 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 Pyrimonas. 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, Streptococcus, 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.

Azithromycin molecular formula: C38H72N2O12 molecular weight: 749

Gastrointestinal reactions such as abdominal pain, diarrhea (loose stools), upper abdominal discomfort (pain or cramps), nausea, and vomiting may occur after taking the drug, and their incidence is significantly lower than that of erythromycin. Mild to moderate abdominal distension, dizziness, headache, fever, rash, joint pain and other allergic reactions may occur occasionally, while anaphylactic shock, angioedema, and cholestatic jaundice are extremely rare. A small number of patients may experience transient neutropenia and elevated serum aminotransferase.

It is contraindicated in patients who are allergic to azithromycin, erythromycin, or any other macrolide drugs.

Precautions for children: The efficacy and safety of treating otitis media, community-acquired pneumonia, and pharyngitis or tonsillitis in children under 6 months of age and under 2 years of age have not yet been determined. Precautions for pregnancy and lactation: Animal experiments have shown that this product has no effect on the fetus, but there is still a lack of experience in its use in pregnant women, so the pros and cons of its use in pregnant women must be fully weighed.

1 It is not suitable to take it at the same time with antacids containing aluminum or magnesium, as the latter can reduce the peak blood concentration of this product; if it must be taken together, this product should be given 1 hour before or 2 hours after taking the above drugs. 2 When used in combination with theophylline, the concentration of the latter in plasma can be increased, and attention should be paid to detecting the plasma theophylline level. 3 When used in combination with warfarin, attention should be paid to checking the prothrombin time. 4 When used simultaneously with the following drugs, it is recommended to observe the patient closely: Digoxin increases the digoxin level. Ergotamine or dihydroergotamine acute ergot toxicity, symptoms are severe peripheral vasospasm and dysesthesia (pain to touch). Triazolam enhances the pharmacological effect of triazolam by reducing the degradation of triazolam. Cytochrome P450 system metabolites increase the levels of carbamazepine, terfenadine, cyclosporine, cyclohexylbarbital, and phenytoin in serum. 5 When used in combination with rifabutin, the latter's toxicity will be increased.

Sealed, store in a dry place.
