FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to antibacterial agents. Lantibiotic solution for bacterial infections contains an aqueous solvent, nisin Z, hydroxytyrosol and a water-soluble polymer component selected from a group comprising a polymer, and/or polymer mixtures, and/or copolymers of vinyl alcohol, vinylpyrrolidone, wherein the lantibiotic solution is a drug preparation. Concentration of the polymer component ranges from 1% to 30% by weight, the concentration of nisin Z ranges from 1 mM to 10 mM, and the concentration of hydroxytyrosol ranges from 1 mM to 100 mM.
EFFECT: lantibiotic solution is effective against both gram-positive and gram-negative bacteria.
