Pharmacological properties


After oral administration, nitroxoline is well and rapidly absorbed from the gastrointestinal tract. The maximum concentration (Cmax) in plasma is reached 1.5-2 hours after ingestion. The half-life (T1 / 2) is approximately 2 hours.

It is excreted mainly by the kidneys in unchanged form, while high concentrations are formed in the urine (100 μg / ml and above).


Nitroxoline has a bacteriostatic effect due to selective inhibition of the synthesis of bacterial deoxyribonucleic acid (DNA). Able to damage the cytoplasmic membrane and reduce the adhesion of uropathogenic strains to urinary tract epithelial cells.

Nitroxoline acts on both gram-positive and gram-negative microorganisms: Staphylococcus spp., Streptococcus spp., Enterococcus faecalis, Corynebacterium diphtheriae, Bacillus subtilis, Escherichia coli, Neisseria gonorrhoeae, Proteus spp., Klebsiella spp., Salmonella spp., Enterobacter spp. .

Active against Mycobacterium tuberculosis, Trichomonas vaginalis, certain types of fungi (Candida spp., dermatophytes, molds and some pathogens of deep mycoses).

Drug Interactions

With the combined use of nitroxoline with drugs of the tetracycline group, the summation of the effects of each drug is observed, with nystatin and levorin – potentiation of the action. It is impossible to combine nitroxoline with nitrofurans in order to avoid the summation of a negative neurotropic effect.


Special instructions

It should be used with caution in renal failure (under the control of the functional state of the kidneys) due to the possible cumulation of the drug.

During treatment, it is possible to stain the urine in a saffron-yellow color.
