Levomycetin powder Pharmacological properties
Pharmacodynamics.

Broad-spectrum antibiotic. Effective against many gram-positive (staphylococci, streptococci, pneumococci, enterococci) and gram-negative bacteria: colibacillus and hemophilus influenzae, salmonella, shigella, klebsiella, serration, yersinia, proteus, gonococci, meningococci, anketeaerobes, rhykydylamines (causative agents of trachoma, psittacosis, inguinal lymphogranulomatosis and others); acts on strains of bacteria resistant to penicillin, streptomycin, sulfonamides; weakly active against acid-fast bacteria, Pseudomonas aeruginosa, clostridia and protozoa. In usual doses it acts bacteriostatically. Inhibits peptidyltransferase and disrupts protein synthesis in a bacterial cell.

Pharmacokinetics.

With intramuscular and intravenous administration, a high concentration of the drug in the blood plasma is quickly achieved (5-10 minutes after intravenous administration, 30-45 minutes after intramuscular administration). The maximum concentration in the blood is reached after 1 hour and remains in effective concentrations in the blood plasma for 8-12 hours. A significant part (60-80%) binds to plasma albumin. Easily penetrates into organs and body fluids, through the blood-brain barrier, through the placenta, into breast milk.

It is excreted mainly by the kidneys in the form of inactive metabolites, partly with bile.
