Mechanism of action

Combined antibacterial drug, the action of which is due to the properties of the components included in its composition. Sulfamethoxazole has a bacteriostatic effect, which is associated with inhibition of the utilization of PABA and impaired synthesis of dihydrofolic acid in bacterial cells. Trimethoprim inhibits an enzyme that is involved in the metabolism of folic acid, converting dihydrofolate to tetrahydrofolate. Thus, Biseptol blocks 2 successive stages of the biosynthesis of purines and, therefore, nucleic acids, which are necessary for the growth and reproduction of bacteria.
Active against gram-positive bacteria: Streptococcus spp., Staphylococcus spp., Listeria monocytogenes, Nocardia asteroides; Gram-negative bacteria: Enterobacter spp., Salmonella spp., Shigella spp., Klebsiella spp., Some strains of Escherichia coli, Moraxella catarrhalis, Haemophilus ducreyi, some strains of Haemophilus influenzae, Brucella spp. A drug is also active in relation to Toxoplasma gondii, Pneumocystis carinii.

After taking the drug inside the active substances are quickly and completely absorbed from the gastrointestinal tract.
Cmax in blood plasma is achieved within 2-4 hours after ingestion.
T1/2 - 10-12 h. Both active substances are excreted in the urine.

Side effects are usually mild and reversible after discontinuation of the drug.


- severe liver dysfunction;
- pronounced impaired renal function (especially if the CC is less than 15 ml / min);

- Severe diseases of the cardiovascular system;
- deficiency of glucose-6-phosphate dehydrogenase;
- pregnancy;
- hypersensitivity to the drug.
The drug is not prescribed to newborns (children under 6 weeks).

Pregnancy and breastfeeding

Biseptol is contraindicated for use in pregnancy.

With the development of disorders on the part of the peripheral blood picture, the administration of folic acid is indicated (at a dose of 5-10 mg / day).


Symptoms: may increase the described side effects.

Drug Interactions

With the simultaneous use of Biseptol enhances the effect of indirect anticoagulants, hypoglycemic agents and Methotrexate.
When combined with phenytoin, barbiturates, PAS Biseptol increases the deficiency of folic acid.
With simultaneous use of barbiturates increase the risk of developing the toxic effects of Biseptolum.
With the simultaneous use of salicylic acid compounds enhance the effect of Biseptol.
