Trimethoprim sulfamethoxazole enhances the action, violating recovery dihydrofolic acid to tetrahydrofolic – the active form of folic acid, which is responsible for protein metabolism and microbial cell division. Is a broad spectrum germicide action, is active against the following organisms: Streptococcus spp, Staphylococcus spp., Streptococcus pneumoniae, Neisseria meningitidis, Neisseria gonorrhoeae, Salmonella spp, Bordetella pertussis, Proteus spp., Pasteurella spp., Brucella spp., Mycobacterium spp., Legionella pneumophila, Morganella spp., Pneumocystis carinii; Chlamydia spp .; protozoa: Plasmodium spp., Leishmania spp. Drug resistance: Corynebacterium spp., Pseudomonas aeruginosa, Mycobacterium tuberculosis, Treponema spp., Leptospira spp., Viruses. Inhibits vital activity of Escherichia coli, which leads to reduced synthesis of thymine, riboflavin, nicotinic acid and other. B vitamins in the intestine.

It is desirable to determine the concentration of sulfamethoxazole in plasma every 2-3 days immediately before the next infusion. If the concentration exceeds sulfamethoxazole 150 mg / ml, treatment should be interrupted as long as it does not fall below 120 mcg / ml. During long-term (more than one month) courses of treatment need regular blood tests because there is the risk of hematological changes. Particular caution should be shown in the treatment of elderly patients or patients with suspected initial lack of folate. During treatment to use foods that contain large amounts of PABA – green parts of plants (cauliflower, spinach, bean), carrots, tomatoes. Avoid excessive solar and UV radiation.

PM, acidifying the urine) increase the risk of crystalluria. Cholestyramine reduces absorption, it should be taken 1 hour after 4-6 hours or until the reception of co-trimoxazole.
