What is Erythromycin?
Erythromycin is an antibiotic from the macrolide group, which has a pronounced antibacterial effect. The active substance is Erythromycin.
When ingested, the antibiotic breaks the bonds between amino acid molecules, blocking the synthesis of bacterial proteins. The systematic use of the drug provides a pronounced bactericidal effect.
Erythromycin is prescribed for diseases provoked by gram-positive bacteria and some gram-negative microorganisms. Most gram-negative bacteria, fungi, mycobacteria, medium and small viruses exhibit resistance.
The spectrum of action includes gram-positive microorganisms: Staphylococcus spp., Producing and not producing penicillinase, including Staphylococcus aureus; Streptococcus spp. (including Streptococcus pneumoniae, Streptococcus pyogenes), alpha-hemolytic streptococcus (Viridans groups), Bacillus anthracis, Corynebacterium diphtheriae, Corynebacterium minutissimum;
Gram-negative microorganisms: Neisseria gonorrhoeae, Haemophilus influenzae, Campylobacter jejuni, Bordetella pertussis, Brucella spp., Legionella spp., incl. 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 to the drug: Escherichia coli, Pseudomonas aeruginosa, as well as Shigella spp., Salmonella spp., Bacteroides fragilis, Enterobacter spp. and etc.
It is an agonist of motilin receptors. It accelerates the evacuation of gastric contents by increasing the amplitude of the reduction of the pylorus and improving antrum-duodenal coordination.
