Septrin D.S.

Composition:

Each tablet contains:

Trimethoprim 160 mg

Sulfamethoxazole 800 mg

Auxiliary components:

potato starch, talc, magnesium stearate, polyvinyl alcohol.

Properties:

Combined antibacterial drug containing sulfamethoxazole and trimethoprim.

Sulfamethoxazole, similar in structure to PABA, disrupts the synthesis of dihydrofolic acid in bacterial cells, preventing the incorporation of PABA into its molecule.

Trimethoprim enhances the effect of sulfamethoxazole, disrupting the reduction of dihydrofolic acid to tetrahydrofolic acid, the active form of folic acid, which is responsible for protein metabolism and microbial cell division.

It is a broad-spectrum bactericidal drug.

Active against the following microorganisms: Streptococcus spp. (hemolytic strains are more sensitive to penicillin), Staphylococcus spp., Streptococcus pneumoniae, Neisseria meningitidis, Neisseria gonorrhoeae, Escherichia coli (including enterotoxigenic strains), Salmonella spp. (including Salmonella typhi and Salmonella paratyphi), Vibrio cholerae, Bacillus anthracis, Haemophilus influenzae (including ampicillin-resistant strains), Listeria spp., Nocardia asteroides, Bordetella pertussis, Enterococcus faecalis, Klebsiella spp. , Brucella spp., Mycobacterium spp. (including Mycobacterium leprae),

Citrobacter spp., Enterobacter spp., Legionella pneumopbila, Providencia, some Pseudomonas species (except Pseudomonas aeruginosa), Serratia marcescens, Shigella spp., Yersinia spp., Morganella spp., Pneumocystis carinii, Chlamydia spp. (including Chlamydia trachomatis, Chlamydia psittaci); protozoa Plasmodium spp., Toxoplasma gondii;

Actinomyces israelii; pathogenic fungi –

Coccidioides immitis, Histoplasma capsulatum; Leishmania spp.

Resistant to the drug: Corynebacterium spp.,

Pseudomonas aeruginosa, Mycobacterium

tuberculosis, Treponema spp., Leptospira spp., Viruses.

It inhibits the vital activity of Escherichia coli, which leads to a decrease in the synthesis of thiamine, riboflavin, niacin and other B vitamins in the intestine.

The duration of the therapeutic action is 7 hours.

Indications:

Treatment of infectious and inflammatory diseases caused by microorganisms sensitive to the drug:

• respiratory tract infections (including bronchitis, pneumonia, lung abscess, pleural empyema);

-otitis, sinusitis;

-infections of the genitourinary system (including pyelonephritis, urethritis, salpingi prostatitis);

-gonorrhea;

• gastrointestinal tract infections (including typhoid fever, paratyphoid fever, bacterial dysentery, cholera, diarrhea);
• infections of the skin and soft tissues (including furunculosis, pyoderma).

Method of administration and dosage:

The drug is taken orally after meals with a sufficient amount of liquid. The dose is set individually.

For adults and children over 12 years of age, the drug is prescribed at 960 mg 2 times / day, with long-term therapy – 480 mg 2 times / day.

The duration of the course of treatment is from 5 to 14 days. In severe cases of the disease and / or in chronic infections, a single dose may be increased by 30-50%.

If the duration of the course of therapy is more than 5 days and / or an increase in the dose of the drug, it is necessary to control the picture of peripheral blood; when pathological changes appear, folic acid should be prescribed at a dose of 5-10 mg / day.

Contraindications:

• an established diagnosis of damage to the liver parenchyma;
• severe renal dysfunction in the absence of the ability to control the concentration of the drug in the blood plasma;
• severe renal failure (CC less than 15 ml / min);

-severe blood diseases (aplastic anemia, B12deficiency anemia, agranulocytosis, leukopenia, megaloblastic anemia, anemia, hyperbilirubinemia in children associated with folic acid deficiency);

-deficiency of glucose-6-phosphate dehydrogenase (risk of hemolysis);

simultaneous use with dofetelide, paclitaxel and amiodarone;

• simultaneous use with clozapine due to the ability of the latter to cause agranulocytosis;

-pregnancy;

-lactation;

-Children up to 3 years old (for this dosage form);

-increased sensitivity to drug components;

hypersensitivity to co-trimoxazole, trimethoprim, sulfonamides.

The drug is prescribed with caution for folic acid deficiency in the body, bronchial asthma, thyroid diseases.

Precautions:

The drug should be prescribed only in case where the advantage of such combination therapy over other antibacterial

monopreparations outweighs the possible risk. Since the sensitivity of bacteria to antibacterial drugs in vitro varies in different geographic areas and over time, local characteristics of bacterial sensitivity should be taken into account when choosing a drug.

Hypersensitivity and allergic reactions

At the first appearance of a skin rash or any other severe adverse reaction, the drug should be discontinued. Patients with a tendency to allergic reactions and with bronchial asthma should be prescribed Septrin@ with caution.

Infiltrates in the lungs (like eosinophilic or allergic alveolitis) can present with symptoms such as coughing or shortness of breath. If these symptoms appear or suddenly worsen, it is necessary to re-examine the patient and consider stopping treatment with Septrin@.

apathy, tremor, peripheral neuritis.
