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