Bacteriostatic antibiotic from the group of tetracyclines. It disrupts the formation of a complex between the transport RNA and the ribosome, which leads to suppression of protein synthesis in the microbial cell.
Active with respect to:
- Gram-positive microorganisms: Staphylococcus spp., in t.ch. Staphylococcus aureus, including strains producing penicillinase; Streptococcus pyogenes, Streptococcus pneumoniae (Diplococcus pneumoniae), Bacillus anthracis, Listeria spp.;
- Gram-negative microorganisms: Escherichia coli, Haemophilus influenzae, Haemophilus ducreyi, Klebsiella pneumoniae, Neisseria gonorrhoeae, Bordetella pertussis, Enterobacter spp., Francisella tularensis (Pasteurella pestis), Salmonella spp., Shigella spp.);
- intracellular (intracellular) and other microorganisms: Chlamydia trachomatis, Chlamydia spp., Mycoplasma spp., Rickettsia spp., Treponema spp.
Resistant to tetracycline microorganisms: Pseudomonas aeruginosa, Proteus spp., Serratia spp., most strains Bacteroides spp. and fungi, viruses, beta-hemolytic streptococcus group A (including 44% of strains Streptococcus pyogenes), as well as 74% of strains Enterococcus (Streptococcus) faecalis.
