Erythromycin Pharmacodynamics
Bacteriostatic antibiotic of macrolide group, binds reversibly to 50S ribosome subunit in its donor part, which disrupts formation of peptide bonds between amino acid molecules and blocks protein synthesis in microorganisms (does not affect nucleic acid synthesis). When used in high doses it can show bactericidal effect. The spectrum of action includes Gram-positive (Staphylococcus spp, producing and not producing penicillinase, including Staphylococcus aureus; Streptococcus spp. Streptococcus pneumoniae, Streptococcus pyogenes, alpha-hemolytic streptococcus (Viridans group), Bacillus anthracis, Corynebacterium diphtheriae, Corynebacterium minutissimum) and Gram-negative microorganisms (Neisseria gonorrhoeae, Haemophilus influenzae, Bordetella pertussis, Brucella spp, Legionella spp. including Legionella pneumophila) and other microorganisms: Mycoplasma spp. (including Mycoplasma pneumoniae), Chlamydia spp. (including Chlamydia trachomatis), Treponema spp., Rickettsia spp., Entamoeba histolytica, Listeria monocytogenes.
Gram-negative bacilli are resistant: Escherichia coli, Pseudomonas aeruginosa, as well as Shigella spp. and Salmonella spp. Microorganisms whose growth is inhibited when the antibiotic concentration is less than 0.5 mg/l, moderately sensitive – 1-6 mg/l, moderately resistant and resistant – 6-8 mg/l are referred to the sensitive group.
