Azab 100 (Azithromycin) is a semi-synthetic antibiotic, the first of a subclass of azalides slightly different in structure from classical macrolides.
Obtained by modifying 14-member macrolides by including the nitrogen atom in the lactone ring between 9 and 10 carbon atoms, in which the ring is transformed into a 15-membered member. This restructuring leads to a significant increase in the acid resistance of the drug – up to 300 times compared to erythromycin.
Action of Azithromycin
Broad spectrum antibacterial azalide, bacteriostatic. Communicating with the 50S-ribosomal subunit, it inhibits peptidtranslokazu in the translation stage, inhibits protein synthesis, inhibits the growth and reproduction of bacteria, in high concentrations it has a bactericidal effect. It acts on extracellular and intracellular pathogens.
Infections of the upper respiratory tract and upper respiratory tract caused by sensitive pathogens: pharyngitis, tonsillitis, laryngitis, sinusitis, otitis media; scarlet fever; lower respiratory tract infections: pulmonary bronchitis (including atypical, chronic exacerbation); skin and soft tissue infections: erysipelas, impetigo, secondarily infected dermatoses; Urinary tract infections caused by Chlamidia trachomatis: gonorrheal and negonoreyny urethritis, cervicitis; Lyme disease (early stage), peptic ulcer and 12 duodenal ulcer associated with Helicobacter pylori (in a combination therapy).
