Combined antibacterial drug, contains sulfamethoxazole and trimethoprim.
Sulfamethoxazole, similar in structure to the PABA, It gives dihydrofolic acid synthesis in bacterial cells, preventing the inclusion of PABA in its molecule.
Trimethoprim-sulfamethoxazole enhances the action, нарушая восстановление дигидрофолиевой кислоты в тетрагидрофолиевую – активную форму фолиевой кислоты, responsible for protein metabolism and microbial cell division.

When the duration of a course of therapy 5 days and / or increasing the dose necessary to control the picture of peripheral blood; the appearance of pathological changes should be appointed at a dose of folic acid 5-10 mg / day.
In Patients with renal insufficiency with CC 15-30 ml / min standard dose Biseptol® must be reduced by 50%.
From the central and peripheral nervous system: headache, dizziness; в отдельных случаях – асептический менингит, depression, apathy, tremor, peripheral neuritis.
The respiratory system: bronchospasm, suffocation, cough, pulmonary infiltrates.
From the digestive system: nausea, vomiting, decreased appetite, diarrhea, gastritis, abdominal pain, glossitis, stomatitis, cholestasis, increase in liver transaminases, hepatitis, sometimes with cholestatic jaundice, gepatonekroz, pseudomembranous enterocolitis, pancreatitis.
From the hematopoietic system: leukopenia, neutropenia, thrombocytopenia, agranulocytosis, megaloblastnaya anemia, aplastic and hemolytic anemia, eozinofilija, gipoprotrombinemii, metgemoglobinemiâ.
From the urinary system: polyuria, interstitial nephritis, impairment of renal function, kristallurija, hematuria, increasing concentrations of urea, giperkreatininemiя, toksicheskaya nephropathy oliguriey and anuriey.
On the part of the musculoskeletal system: arthralgia, myalgia.
Allergic reactions: itch, photosensitivity, hives, drug fever, rash, erythema multiforme exudative (incl. Stevens-Johnson syndrome), toxic epidermal necrolysis (Lyell's syndrome), exfoliative dermatitis, allergic myocarditis, fever, angioedema, redness of the sclera.

Preparation, usually, well tolerated.
FROM caution prescribers deficiency of folic acid in the body, asthma, Thyroid diseases.
Bïseptol® contraindicated during pregnancy and lactation (breast-feeding).
With care prescribe a drug for allergic history.
At long (more than a month) courses of treatment requires regular blood tests, because there is the risk of hematological changes (often asymptomatic). These changes may be reversible when assigning folic acid (3-6 mg / day), that does not significantly impair the antimicrobial activity of the drug. Particular care is required when treating elderly patients or patients with suspected initial lack of folate. Purpose of folic acid is also advisable when chronic treatment drug at high doses.
To prevent crystalluria is recommended to maintain a sufficient volume of urine. Chance of toxic and allergic complications of sulfonamides substantially increases with a decrease in kidney filtration function.
It is inappropriate and against the background of the treatment consumed foods, containing large amounts of PABA, – зеленые части растений (cauliflower, spinach, pulse), carrot, tomatoes.
Avoid excessive sun and UV radiation.
The risk of side effects is considerably higher in AIDS patients.
Do not use the drug if tonsillitis and pharyngitis, caused by β-hemolytic streptococcus group A, because of widespread resistance strains.
Trimethoprim can change the results of the determination of serum levels of methotrexate, conducted by an enzymatic method, but does not affect the results when radioimmunoassay.
Co-trimoxazole may increase on 10% Results Jaffe reaction with picric acid for the quantitative determination of creatinine.
Symptoms: anorexia, kišečnaâ how, nausea, vomiting, dizziness, headache, drowsiness, loss of consciousness, It may also have a fever, hematuria, kristallurija. Later may develop bone marrow suppression, and jaundice.
After acute poisoning trimethoprim nausea, vomiting, dizziness, headache, depression, disturbance of consciousness, suppression of bone marrow function.
Unknown, what dose of co-trimoxazole can be life-threatening.
Chronic poisoning: co-trimoxazole at high doses for prolonged periods can lead to suppression of bone marrow function, manifested by thrombocytopenia, leucopenia or anemia megaloblastic.
Treatment: removal of the drug and taking action, aimed at removing it from the blood (to gastric lavage within 2 h after ingestion or vomit), excessive drinking, If urine output is insufficient, and preserved renal function. Enter calcium folinate (5-10 mg / day). The acidic environment accelerates the excretion of urine trimethoprim, but it may also increase the risk of kidney crystallization sulfonamide.
It should monitor the blood picture, Electrolyte composition in plasma and other biochemical parameters. Hemodialysis is moderately effective, and peritoneal dialysis are not effective.
In an application Biseptol® with thiazide diuretics are at risk of thrombocytopenia and bleeding (the combination is not recommended).
Co-trimoxazole increases the anticoagulant activity of indirect anticoagulants, and the action of hypoglycemic drugs and methotrexate.
Co-trimoxazole reduces the intensity of the hepatic metabolism of phenytoin (increases egoT1/2 on 39%) and warfarin, reinforcing their effects.
Rifampicin reduces T1/2 Trimethoprim.
With simultaneous use of pyrimethamine at doses, exceeding 25 mg / Sun., It increases the risk of megaloblastic anemia.
With simultaneous use of diuretics (often thiazides) increase the risk of thrombocytopenia.
Benzokain, prokayn, prokaynamyd (Like other drugs, by hydrolysis which is formed PABA) reduce the effectiveness of Biseptol®.
Between diuretics (incl. with thiazide, furosemidom) and oral hypoglycemic agents (sulfonylureas) one side, и антибактериальными средствами группы сульфаниламидов – с другой стороны, possible development of cross-allergic reaction.
Phenytoin, barbiturates, PAS increase the expression of folate deficiency while the use of Biseptol®.
Salicylic acid derivatives enhance the effect Biseptol®.
Vitamin C, geksametilentetramin (Like other drugs, acidifying the urine) increase the risk of crystalluria against application Biseptol®.
Cholestyramine reduces absorption when taken with other drugs, it should be taken over 1 h after or 4-6 hours prior to receiving co-trimoxazole.
In an application with drugs, suppress bone marrow hemopoiesis, increases the risk of myelosuppression.
In some cases Biseptolum® can increase the concentration of digoxin in the blood plasma of elderly patients.
Bïseptol® It may decrease the effectiveness of tricyclic antidepressants.
In patients following kidney transplantation, while the use of co-trimoxazole and cyclosporin, celebrated passing the transplanted kidney dysfunction, manifested by increased serum creatinine, which is probably caused by the action of trimethoprim.
Reduces the effectiveness of oral contraceptives (It inhibits the intestinal microflora and reduce enterohepatic circulation of hormonal agents).
The drug is released under the prescription.
