Clinical Pharmacology


Antimicrobial, 8-hydroxyquinoline derivative. It has a wide spectrum of action. Selectively inhibits the synthesis of bacterial DNA, forms complexes with metal-containing microbial cell enzymes.

Active in relation to:

Gram positive bacteria: Staphylococcus spp. (including Staphylococcus aureus); Streptococcus spp., Including: Beta-hemolytic streptococci; Streptococcus pneumoniae; Enterococcus faecalis; Corynebacterium spp; Bacillus subtilis.

Gram-negative bacteria: Escherichia coli; Proteus spp; Klebsiella spp; Salmonella spp; Shigella spp; Enterobacter spp; Haemophilus influenzae; Neisseria gonorrhoeae.

Other microorganisms: Ureaplasma urealyticum; Mycoplasma hominis; Mycobacterium tuberculosis; Trichomonas vaginalis.

Some types of mushrooms: candida, dermatophytes, mold fungi, some causative agents of deep mycoses.



Nitroxoline is well absorbed from the gastrointestinal tract (90%). WITHmax in plasma is reached in 1.5-2 hours after ingestion.

Metabolism and excretion

Metabolized in the liver. Excreted mainly by the kidneys unchanged and partially with bile. There is a high concentration of conjugated and unconjugated drug in the urine.


Treatment of acute, chronic and recurrent urinary tract infections caused by microorganisms sensitive to nitroxoline:

  • pyelonephritis;
  • cystitis;
  • urethritis;
  • epididymitis;
  • an infected prostate adenoma or carcinoma.

Prevention of infectious complications in the postoperative period:

  • in surgical interventions on the kidneys and urinary tract;
  • with diagnostic and therapeutic procedures: catheterization, cystoscopy.

Prevention of recurrent urinary tract infections.
