Release form and composition
The substance that provides Biseptolu therapeutic effect, called co-trimoxazole. This name combines two active compounds, the ratio of which in one tablet is 5 to 1. Depending on the number of such active substances, the preparation is represented by two dosages:
- 120 mg tablets, in which there is 100 mg of sulfamethoxazole, supplemented with 20 mg of trimethoprim.
- 480 mg tablets, of which the patient receives sulfamethoxazole in the amount of 400 mg, and trimethoprim in the dose of 80 mg.
Biseptol tablets are distinguished by a round flat shape, white (sometimes yellow) color, and the presence of risks and Bs engraving. They are packaged in blisters of 20 pieces and sold for 1 blister in a pack.
Biseptol (480, 120, and 240 mg) is a broad-spectrum antimicrobial drug that refers to sulfanilamide drugs. The combination of active substances prevents the synthesis of folic acid, which is responsible for metabolic processes in microbial cells, as well as their division.
Co-trimoxazole does not kill the causative agents of various diseases, but limits their reproduction, giving the immune system the ability to cope with pathogens on its own. This explains the absence of a strong toxic effect during Biseptol treatment.
The drug is able to cope with approximately 40 types of pathogenic microorganisms, including streptococcal and staphylococcal infections, Vibrio cholerae, Toxoplasma, Salmonella, Chlamydia, E. coli and others. Anaerobic and mycobacteria, as well as viruses, the drug has no effect.
It is also used for primary and secondary prevention of pneumocystosis and toxoplasmosis in HIV carriers.

The action of the drug due to the fact that it blocks the synthesis of folic acid, without which the microbial cell can not divide. Sulfamethoxazole and trimethoprim complement and reinforce each other in this mechanism.

We picked up some reviews of people about the drug Biseptol:
- Olga I consider “Biseptol” an old, reliable, proven drug that helps in solving the problems of not only the sick respiratory organs, but also of ulcers, barley, and diarrhea. She treated herself and her children with success. I know that it is bad for the liver, because it consumed it only after eating and drinking milk. In the battle with broncho-pulmonary diseases, it is obligatory to take 4 tablets per day, 2 times with an equal interval within 3-5 days, depending on the severity. For ulcers, one or two single intakes of 2 tablets are sufficient, and it saves diarrhea from one administration in the same number of tablets. Wonderful drug!
