Pharmacological action
Combined antimicrobial, consisting of sulfamethoxazole and trimethoprim. Sulfamethoxazole, similar in structure to para-aminobenzoic acid (PABA), It gives dihydrofolic acid synthesis in bacterial cells, preventing the inclusion of PABA in its molecule. Trimethoprim-sulfamethoxazole enhances the action, violating recovery digidrofolievoy tetrahydrofolic acid – the active form of folic acid, responsible for protein metabolism and microbial cell division.
It is a bactericidal broad-spectrum drugs, 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 strains enterotoksogennye), Salmonella spp. (including Salmonella typhi and Salmonella paratyphi), Vibrio cholerae, Bacillus anthracis, Haemophilus influenzae (including ampicillin resistance strains), Listeria spp., Nocardia asteroids, Bordetella pertussis, Enterococcus faecalis, Klebsiella spp., Proteus spp., Pasteurella spp., Francisella tularensis, Brucella spp., Mycobacterium spp. (incl. Mycobacterium leprae), Citrobacter, Enterobacter spp., Legionella pneumophila, Providence, some species Pseudomonas (other than Pseudomonas aeruginosa), Serratia wilting, Shigella spp., Yersinia spp., Morganella spp., Pneumocystis carinii; Chlamydia spp. (incl. Chlamydia trachomatis, Chlamydia psittaci); protozoa: Plasmodium spp., Toxoplasma gondii, pathogenic fungi, Actinomyces israelii, Merciless coccidioides, Histoplasma capsulatum, Leishmania spp.
Drug resistance: Corynebacterium spp., Pseudomonas aeruginosa, Mycobacterium tuberculosis, Treponema spp., Leptospira spp., viruses.
Inhibits E. coli livelihoods, which leads to reduced synthesis of thymine, riʙoflavina, nicotinic acid, etc.. B vitamins in the intestine.
Pharmacokinetics
In peroralynom accept absorption – 90%. TCmax – 1-4 no, therapeutic concentration level is maintained 7 h after a single dose. It is well distributed in the body. It penetrates through the BBB, the placenta and breast milk. The lungs and urine concentrations creates, excess plasma levels. To a lesser extent in the bronchial secretions accumulate, vaginal secretions, secretions and tissues of the prostate, middle ear fluid (when inflammation), cerebrospinal fluid, bile, bones, saliva, the aqueous humor of the eye, breast milk, interstitial fluid. Relationship to plasma proteins – 66% in sulfamethoxazole, trimethoprim in – 45%.
Mostly sulfamethoxazole is metabolised to produce acetylated derivatives. Metabolites possess an antimicrobial activity.
Excreted by the kidneys as metabolites (80% during 72 no) and unaltered (20% sulfamethoxazole, 50% Trimethoprim); negligible quantity – through the intestine. T1/2 sulfamethoxazole – 9-11 no, Trimethoprim – 10-12 no, children – significantly less, depending on the age: to 1 year – 7-8 no, 1-10 years – 5-6 no. In elderly and patients with impaired renal function T1/2 increases.

Cautions
It is advisable to determine the concentration of sulfamethoxazole in plasma every 2-3 days immediately before the next infusion. If the concentration exceeds sulfamethoxazole 150 ug / ml, treatment should be interrupted until, until it drops below 120 ug / ml.
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 caution should be shown in the treatment of elderly patients or patients with suspected initial lack of folate. Purpose of folic acid is also advisable when chronic treatment with 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, contain large quantities of PABA, – green parts of plants (cauliflower, spinach, pulse), carrot, tomatoes.
Avoid excessive sun and UV radiation.
The risk of side effects is significantly higher in patients with AIDS.
Not recommended for tonsillitis and pharyngitis, caused by beta-hemolytic streptococcus group A, because of widespread resistance strains.
