Azithromycin (Sumatrolid Solution Tablets) dispersible 250 mg – [6 tablets]

Azithromycin is a bacteriostatic broad-spectrum antibiotic of the macrolide-azalide group. It has a broad spectrum of antimicrobial action. Azithromycin mechanism of action is associated with inhibition of microbial cell protein synthesis. Binding to 508-subunit of ribosome, it inhibits peptide translocase at the translation stage and inhibits protein synthesis, slowing down the growth and reproduction of bacteria. At high concentrations it has a bactericidal effect.

It has activity against a number of Gram-positive, Gram-negative, anaerobic, intracellular and other microorganisms.

Microorganisms may be initially resistant to the action of the antibiotic or may become resistant to it.

Sensitivity scale of microorganisms to azithromycin (Minimum inhibitory concentration (MIC), mg/L):

Infectious and inflammatory diseases caused by microorganisms sensitive to azithromycin:

– Infections of the upper respiratory tract and ENT organs: pharyngitis, tonsillitis, sinusitis, otitis media;

– Lower respiratory tract infections: acute bronchitis, exacerbation of chronic bronchitis, pneumonia, including those caused by atypical pathogens;

– Skin and soft tissue infections: rye, impetigo, secondary infected dermatoses;

– initial stage of Lyme disease (borreliosis) – erythema migrans

– Infections of the urogenital tract (urethritis, cervicitis) caused by Chlamydia trachomatis

Hypersensitivity to azithromycin, erythromycin, other macrolides or ketolides or other drug components; severe hepatic impairment; phenylketonuria; children under 3 years of age; simultaneous use with ergotamine and dihydroergotamine.
